Benzoyl Peroxide Powder Usage and Synthesis.

Benzoyl peroxide is a strong oxidizing agent, which can be used to bleach organic matter, such as flour, vegetable oil, etc. However, it has a strong destructive effect on β-carotene, vitamin A, vitamin E and vitamin B1 in flour, and the maximum use amount is 0.25-0.3g/kg flour;

it is easily decomposed into free radicals when heated to 70-90℃, and is widely used as an initiator for the polymerization of alkene monomers (vinyl chloride, acrylonitrile, etc.) and photochemical reactions.

It is widely used as an initiator for the polymerization reaction of alkene monomer (vinyl chloride, acrylonitrile, etc.) and photochemical reaction, and the excessive amount will cause the polymer to change color and become yellow. Benzoyl peroxide can decompose rapidly when heated to about 100℃ and can cause explosion in sealed containers, so it should be treated as dangerous goods.

Benzoyl Peroxide Powder is an organic compound with the chemical formula C_14H_10O_4. It is a white crystal, soluble in benzene and ethanol, insoluble in benzoyl peroxide CAS 94-36-0 is a commonly used free radical initiator in organic synthesis reactions.

Benzoyl Peroxide Raw Materials is a strong oxidizing agent, which can be used to bleach organic materials Benzoyl Peroxide is a strong oxidizing agent, which can be used to bleach organic materials, such as flour, vegetable oils and fats, but has a strong destructive effect on β-carotene, vitamin A, vitamin E and vitamin B1 in flour.

Benzoyl peroxide is sensitive to impact and friction and has a high risk of explosion. Contact with metallic powders, activated carbon and reducing agents should be avoided and the safety precautions on the container label should be observed.

To prevent the danger of fire and explosion, it is usually used after diluting to about 20% with 3 or more substances such as calcium carbonate, calcium phosphate, calcium sulfate, magnesium carbonate, alum and starch (diluted benzoyl peroxide). 

Application/Function of Benzoyl Peroxide Powder.

Benzoyl peroxide gel is an oxidizing agent for external use on the skin in concentrations of 2.5%, 5% and 10%. It may be bactericidal by slowly releasing neo-oxygen oxidizing bacterial proteins and has antibacterial effects on Propionibacterium acnes and is also effective against anaerobic infections. It also has mild keratolytic and desquamative effects and reduces free fatty acids in the sebaceous glands of hair follicles.

In addition this drug stimulates epidermal proliferation and granulation tissue formation in the treatment of bedsores and bruised ulcers. Benzoyl peroxide is absorbed through the skin and metabolized to benzoic acid, which is then excreted in the urine as benzoate.

Mechanism of action of Benzoyl Peroxide Powder:

Benzoyl peroxide is also known as benzoyl peroxide, benzoyl peroxide, Acetoxyl, Acnegel, Benoxyl, Lucidol, Nericur, Xerac, BP5. white rhombohedral crystals or crystalline powder. Slight benzaldehyde odor.

Has a bitter kernel taste. Relative molecular mass 242.23. Relative density 1.3440(25℃). Melting point 103～106℃(decomposition and, explosion). Refractive index 1.545. flash point 125℃. Strong oxidizer, easy to burn, easy to explode. Very slightly soluble in water, slightly soluble in methanol, isopropanol, soluble in ethanol (1.2g/100g), acetone (18.5g/100g), chloroform (26.8g/100g), ethyl acetate (14.4g/100g), benzene (18.6g/100g), ether (8.6g/100g).

Half-life in solution is 2.1h (85℃), 10h (72℃). Decomposes slowly in alkali solution. Stable at room temperature, easy to explode in dry state due to friction, impact or heating. Add sulfuric acid can burn. Because it is a strong oxidizing agent, it can cause skin and mucous membrane inflammation. Oral LD503949mg/kg in mice.

Preparation process of Benzoyl Peroxide Powder.

Used as initiator of monomer polymerization of polyvinyl chloride, unsaturated polyester, polyacrylate, etc. It can also be used as cross-linking agent of polyethylene, and as vulcanizing agent of rubber.

Used as analytical reagent, oxidizing agent, bleaching agent and initiator of plastic polymerization.

The powder type products are mainly used as polymerization initiators for acrylic resins, MMA resins, etc. In recent years, it is being promoted as a fast binder for highway engineering, etc. The paste type is used as a curing catalyst for polyester resin molding process.

The liquid type is used as a polymerization catalyst for the preparation of polystyrene resins.
