What Is Boric Acid Used For?

 Boric Acid Suppliers will share this article with you.

Boric acid is a water-soluble white compound that occurs naturally. It is composed of oxygen, boron and hydrogen. It is said to have antifungal and antibacterial properties. Before applying boric acid to any part of the body, be sure to consult your healthcare provider. It irritates the skin and may cause severe reactions.

Uses can include:

Boric acid is usually part of homeopathic medicine and is used to treat vaginal discharge and itching. This medicine is a combination of beneficial bacteria, vitamin E and a small amount of boric acid.

It is usually diluted to treat diaper rash, insect bites and sunburn.

Boric acid is an effective pesticide for killing cockroaches, mice and flies.

Boric acid is called a swimming pool chemical because it has proven to be very useful for maintenance. It can help stabilize the pH of the water and prevent algae problems. This product reduces the chlorine required in swimming pools. This compound can help keep the water clear and sparkling. It can also be used to remove fungi in pool water.

It also helps treat various ear infections in humans and pets. It is not recommended for children to use boric acid.

It also helps treat foot odor. People who suffer from foot odor can mix boric acid powder and talcum powder on the inside of their shoes.

Boric acid can be used as a wound spray after mixing with distilled water. This solution contains bactericidal ingredients that help treat small wounds such as cuts and burns. This cannot be used too frequently.

When washing clothes, adding boric acid to ordinary detergents can help remove stubborn stains on clothes.

They are used to remove dust and odors from kitchens and bathrooms.

Due to its flame retardant properties, boric acid is widely used in the manufacture of furniture, mattresses and insulating materials. Boric acid helps protect the wood from fungi and insects.

Industrially used to manufacture fiberglass, household glass products, and liquid crystal display (LCD) glass. In order to produce glass with better chemical resistance and high temperature resistance, boric acid is used in glass products.

Boric acid is a good cleaning agent that can remove all kinds of molds and insects, such as ants, cockroaches, silverfish, fleas, etc.

Boric acid is also used in leather manufacturing, and it is used in the jewelry industry along with denatured alcohol.

Boric acid is also used as a flux by blacksmiths.

Its mixture with petroleum or vegetable oil is an excellent lubricant that can be used on ceramic or metal surfaces.

Manufacturers use boric acid in various products such as enamels, pesticides, glazes and paints.

Boric acid is widely used to treat boron deficiency in plants.

It is naturally found in vegetables, most fruits, grains and nuts. However, we cannot tell because boric acid crystals are odorless and tasteless. In nature, it is very toxic. However, boric acid is toxic if swallowed or inhaled in large quantities. High concentrations of boric acid may cause reproductive problems, kidney damage, endocrine disorders, increased liver enzymes, abdominal pain, allergic reactions, burning sensation, irritation, central nervous system (CNS) irritation, central nervous system depression, diarrhea, skin rash, and vomiting.

Crown Ether

 Crown ether is a newly developed compound with special complexing properties after the 1970s. Because of its crown-like shape, it is also called "crown compound". It is a type of [CH2CH2Y] n (n>Crown ether in a narrow sense refers to the macrocyclic polyether Y is O, such as 18-crown-6 and dicyclohexyl-18-crown-6. They are named after the order of non-ring substituents, number of ring atoms, class name (crown) and number of ring hetero atoms are named according to common nomenclature, such as dibenzo-18-crown-6. Saturated crown ether is a colorless viscous liquid or low melting solid while aromatic ring-containing crown ether is colorless crystal. Crown ethers containing aromatic rings are insoluble in water, alcohol and common organic solvents at room temperature, but are more soluble in dichloromethane, chloroform, pyridine and formic acid. Crown ethers containing cyclohexyl groups are more soluble in water, alcohols, aromatic hydrocarbons and petroleum ethers than the corresponding benzo crown ethers.

Crown ethers

Crown ethers generally have good thermal stability. However, its ether bonds are easily oxidized when melted or at high temperatures. The aromatic ring in the molecule can participate in bromination, nitration, esterification and ozonation, and can also form a polymer with formaldehyde during condensation. Crown ether can form a complex substance called cryptoester, which makes many salts soluble in non-polar organic solvents, so many difficult reactions can be carried out easily. The stronger the lipophilicity, the stronger the catalytic activity. In addition, the reaction is selective because its fixed space can only accommodate ions of the corresponding size. The stability of the polyether ring formed by the crown ether and the positive ion mainly depends on the relative size of the polyether ring and the positive ion; because the compound is formed by electrostatic interaction, the stability constant is generally small. What makes the reaction convenient is that the complex is easily decomposed by adding water, dilute acid or thermal decomposition.

Preparation method: generally use Williamson (Williamson) ether synthesis. But in order to prevent chain polymerization, it is recommended to use high dilution method, hierarchical condensation and template reaction.

At present, the most widely used and easily available crown ethers are 18-crown-6, dibenzo-18-crown-6 and dicyclohexyl-18-crown-6. The formation of complexes between crown ethers and metal cations is an important feature of crown ethers, which can be used for phase transfer catalysis in organic synthesis.

Key Difference-Enols vs Enolates vs Enamines

Enols, enolates and enamines are three different types of organic compounds. Enol is also called olefin alcohol. This is because enols are formed by combining olefins and alcohols. It is a reactive structure because the enol appears as an intermediate compound in a chemical reaction. Enolates are derived from enols. Enolates are conjugate bases of enols. This means that the enolate is formed by removing a hydrogen atom from the hydroxyl group of the enol. Enamine is an amine compound that contains an amine group near the double bond. The chemical reactivity of enolates and enamines are almost similar. The key difference between enol, enolate and enamine is that the enol contains a hydroxyl group with an adjacent C=C double bond and enolates contain a negative charge on the oxygen atom of an enol whereas the enamines contain an amine group adjacent to the C=C double bond.

What is enol?

Enol is an organic compound that contains a hydroxyl group (C=C double bond) adjacent to the alkene group. Enol is formed by the combination of alcohol and olefin. The name of this compound is derived from the original compound it was formed; "en" comes from alkene, and "ol" comes from alcohol.

Compared with enolates and enamines of the same molar mass, enols have the lowest nucleophilic activity. This means that the enol has poor nucleophilicity. However, its nucleophilicity is controlled by the electron-rich pi bond, which consists of the extra electron density from the oxygen atom of the hydroxyl group.

Enols are usually obtained by removing a hydrogen atom from the alpha carbon of the carbonyl compound. Carbon is the carbon atom close to the carbonyl group. This is a deprotonation reaction because it involves the removal of protons. If this proton does not return, an enol acid ion is formed.

Enol

What are enolates?

Enolates are conjugate bases of enols. Therefore, the enolate is formed by removing a hydrogen atom from the hydroxyl group of the enol. Enolate is the anionic form of enol. The enolate has a negative charge on the oxygen atom, which is located near the C=C double bond. The hydrogen atom in the hydroxyl group of the enol can be removed and react with the base to form the enolate. Aldehydes or ketones react with appropriate bases to obtain enolate.

Enolates have high nucleophilicity and can react effectively with electrophiles. The nucleophilic activity of enolates is higher than enols and enamines. The nucleophilicity of enolate anions is caused by several reasons.

The atomic radius of the oxygen atom is very small

Enolates are formally negatively charged

Compared with enamine, the oxygen in enolate has higher electronegativity than the nitrogen atom in enamine

What is enamine?

Enamines are organic compounds composed of amine groups adjacent to C=C double bonds. Enamine is formed by the condensation of aldehydes or ketones with secondary amines. Enamines are considered to be the nitrogen analogues of enols.

Can Boric Acid Help Treat Yeast Infections?

Boric acid is an effective way to treat yeast infections. When other antifungal drugs do not work, doctors recommend using it as a second-line treatment.

Boric acid can prevent the growth of Candida. This acid can be used as a vaginal suppository.

A small amount of yeast on the skin, mouth, throat, and vagina is healthy. In some cases, such as when the immune system is weak or hormones change during pregnancy, yeast may multiply and cause infection.

The medical term for yeast infections is candidiasis. Yeast infections are common and often occur in the vagina. They are usually caused by C. albicans or C. glabrata fungi.

Boric acid is a white powder or crystalline solid, which acts as a powerful antiviral and antifungal agent in the body. Studies have shown that boric acid inhibits the growth of Candida albicans and Candida glabrata. It interferes with the natural life cycle of yeast and prevents it from growing and becoming infectious.

According to trusted sources from the Centers for Disease Control and Prevention (CDC), if other antifungal drugs or ointments cannot treat yeast infections or recurrences, people should use boric acid as a secondary treatment.

Boric acid may be able to treat infections that are resistant to first-line treatment. This is usually an antifungal medication and may include a single oral fluconazole or topical antifungal cream. If none of these work, the doctor may recommend boric acid or other treatments such as nystatin or flucytosine.

People can use gelatin capsules as vaginal suppositories. The US Centers for Disease Control and Prevention recommends taking capsules containing 600 mg of boric acid once a day for two weeks.

Boric acid medications are usually affordable. You can buy them over the counter in pharmacies or online.

If symptoms persist after taking boric acid, please consult your general practitioner or gynecologist.

Boric acid vaginal suppositories are available. They are an oval-shaped solid capsule that people can insert into the vagina. When they heat up to the temperature of the body, they become liquid.

To treat Candida infections, CDC recommends vaginal suppositories containing 600 mg of boric acid. People should use it once a day for two weeks.

Be sure to take the medicine according to the instructions on the medicine label.

Before using vaginal suppositories, make sure your hands and vaginal area are clean and dry to prevent bacteria from entering your body.

To use suppositories, a person should:

Fill up the applicator, lie on your back with your knees bent, or stand with one foot raised on a chair.

Gently insert the applicator into the vagina.

Press the plunger to release the capsule.

Gently remove the applicator.

Some instructions suggest using suppositories before going to bed. This is because lying down can reduce the risk of medicine leakage.

It is safe to use suppositories during menstruation. Use menstrual pads instead of tampons, because tampons will absorb some medications.

Is Silane Harmful?

Silane is a kind of fire at normal temperature and pressure; it will explode in air or halogen gas. Its fire and explosion are the result of reaction with oxygen. Silane is very sensitive to oxygen and air, that is, if the concentration is not low enough, it is diluted with other gases. When silane contains 2% in argon, 2.5% in nitrogen and 1% in hydrogen, it can still catch fire. Silane concentration is non-flammable when it is less than 1%, spontaneously ignited when greater than 3%, and combustible when 1% to 3%. As long as it has a certain concentration of silane, it will react explosively with oxygen at a temperature of -180°C.

Silane is a colorless gas that reacts with air and may cause suffocation. This gas usually burns when in contact with air, releasing dense white amorphous silica fumes. Its main health hazard is that its spontaneous flame can cause severe thermal burns, which can even be fatal if it is severe. If flame or high temperature acts on a certain part of the silane cylinder, the cylinder will explode before the safety valve is activated. If the pressure is too high or the speed is too fast when the silane is discharged, it will cause a hysteresis explosion. If the leaked silane does not ignite spontaneously, it will be very dangerous. Personnel dealing with emergency situations must have personal protective equipment and fire-fighting facilities adapted to the situation. Don't try to put out the fire before the gas supply is cut off.

The most important hazards and effects:

Eye contact: Diphenylsilane can irritate the eyes. The decomposition of silane produces amorphous silica. Eye contact with amorphous silica particles can cause irritation.

1. Inhalation of high concentrations of silane can cause headache, nausea, dizziness and irritation of the upper respiratory tract.

2. Silane can irritate the respiratory system and mucous membranes. Due to the presence of silicon crystals, excessive inhalation of silane can cause pneumonia and kidney disease.

Eye contact: Immediately rinse with clean water for at least 15 minutes, not too quickly, while opening the eyelids. Make the victim's eyes a "0" shape, and immediately seek ophthalmological treatment.

3. Exposure to high concentrations of gas can also cause spontaneous heat burns. Ingestion is unlikely to be a way of exposure to silane.

Skin contact: Silane can irritate the skin. The decomposition of silane produces amorphous silica. Skin contact with amorphous silica particles can cause irritation.

Three Ways You Can Use Boric Acid Today

Boric acid manufacturer will share this article with you.

Boric acid is a white or colorless, odorless and tasteless compound.

It is a mild acid, relatively non-toxic to the human body, non-carcinogenic, and widely used in households.

It is also used in cosmetics and pharmaceutical products, pest control, and even in manufacturing.

Below are the three most common uses of boric acid in the home we have found.

Use scorched earth to control pests at home

Boric acid is considered to be one of the most effective and natural ways to get rid of those nasty pests at home. It is used to kill cockroaches, ants, fleas, termites, silverfish, beetles, wood borers and other parasites.

When boric acid is ingested, it produces stomach poison, which makes the insect's body dry. It can also decompose the wax on insect shells and be absorbed into the body. But unlike other toxins, insects have no immunity to boric acid. More importantly, it is not an insect repellent, so they will not avoid the place where you applied it, but keep coming back and then getting poisoned.

You have two options: you can buy a pesticide with boric acid as the main ingredient, or you can make it yourself. Mix equal parts of boric acid, flour and dust all over the house, especially in cracks and corners. However, when doing this, you must open the window to minimize the chance of inhaling this substance. Don't forget to vacuum after.

The insecticidal ability of boric acid can also be extended to furniture. A mixture of boric acid and water can be sprayed on the wood to prevent harmful insects such as termites or beetles, wood rot and fungi. Another option is to drill a hole in the wood and insert into it a pellet or water-soluble capsule containing boric acid.

An easy choice for skin care and first aid

Boric acid is a natural preservative, antifungal and astringent. Adding a teaspoon of boric acid to four ounces of distilled water can clean wounds, rashes, minor burns, or treat acne. It also relieves the itching caused by mosquito bites. A teaspoon of water in four cups of water can be used to treat eye pain, irritation, or strange eye discharge.

Due to its antifungal properties, it is also used to treat external fungal infections. Sprinkling a small amount in your shoes can treat athlete’s foot. Boric acid dissolved in water is also an effective way to treat ear infections caused by fungi for swimming pools. The infection must disappear within two to three days.

Use this cleaning agent to make your laundry full of vitality

Boric acid can also be used as a cleanser, detergent, disinfectant, deodorant and mildew removal agent. To remove stains and odors from clothes, just add half a cup to the daily laundry. You can also use it to clean your sink, floor, bathroom and windows. Pour half a cup of boric acid into the toilet and let for 30 minutes. It not only removes stains, but also removes odors. To deodorise a refrigerator, sprinkle a thin layer of powder on it and leave for 15 minutes. Then, wash off the powder and wipe dry.

The mixture of water, hydrogen peroxide and boric acid can remove mould very effectively. Spray on the affected area and scrub it clean. Make sure to do this when the mould is wet, otherwise the spores will spread through the air and cause disease, or move to other places.

Boric Acid

Boric acid, with the chemical formula H₃BO₃, is a white powdery crystal or a scaly shiny crystal with a triclinic axis. It feels slippery and has no taste. It is soluble in water, alcohol, glycerin, ether and essential oils, and the aqueous solution is weakly acidic. It is widely used in glass (optical glass, acid-resistant glass, heat-resistant glass, glass fiber as insulating material) industry to improve the heat resistance and transparency of glass products, increase mechanical strength, and shorten melting time.

Boric acid and borax are illegal food additives , but there are still unscrupulous players who illegally use the two to increase the elasticity and toughness of food, extend the shelf life or keep the color beautiful, even in addition to alkaline dumplings, other foods, such as rice cakes, oil Noodles, dumplings, fish dishes, shrimps, often seeking "taste" are also often affected.

Although boric acid itself is not very toxic, it has a "cumulative effect" in the body. Although it is not taken every time, it will accumulate in the body after continuous intake. It may also damage the central and digestive system, hinder the function of digestive enzymes, cause loss of appetite, inhibit nutrient absorption, promote fat decomposition, and cause weight loss and other symptoms. In addition, in the study of boric acid ingestion in mice, mice and dogs, it has also been observed that long-term or short-term intake of large amounts of boric acid or borax can affect the male reproductive system, such as testicular atrophy. However, boric acid has not been observed to have a significant carcinogenic effect or cause genetic mutations, and no International Cancer Research Center (IARC) has classified it as a carcinogen.

In terms of dosage, adults taking 1 to 3 grams of boric acid will cause symptoms of "boric acid poisoning", including vomiting, diarrhea, skin erythema, and even risk of shock or coma; oral lethal dose is 15 to 20 grams for adults and 5-6 for babies Grams, 2-3 grams for babies.

If the laboratory is splashed by strong alkali, in addition to washing with a lot of water, it should also be coated with boric acid solution. Neutralize the residual strong base. This is the most basic and a recent usage. (If there is no boric acid solution around and it is splashed by strong alkalis, carbonic acid can be used in an emergency, but it is best to use boric acid, because boric acid is also an acid, which is weaker than the carbonic acid in cola.)

Boric acid is also one of the basic raw materials for the production of other borides. The boron compounds produced are widely used in national defense and other industrial departments and scientific research units. Used as a pH regulator, antibacterial preservative.
