Henan Sheng Taiyuan direct benzoyl peroxide

Formula: C14H10O4 Molecular Weight: 242.22 CASNo:. 94-36-0 Uses: analysis reagents, oxidants, bleach and plastic polymerization initiator properties: white crystalline powder Melting point 103-106 ℃ (decomposition), soluble in benzene, chloroform, benzene, carbon disulfide, slightly soluble in water and ethanol. Nature is very unstable, friction, impact, the case of Mingguang, high temperature, sulfur and reducing agents, has caused a risk of explosion. Storage should be 25-30% of the injected water. Preparation: make 30% caustic hydrogen peroxide reacts with the sodium peroxide solution, then reacted with benzoyl chloride derived. The reaction at 0 ℃, at temperatures too high to cause decomposition of hydrogen peroxide, benzoyl chloride acid hydrolysis is also easy to affect yield. The resultant precipitate benzoyl peroxide filtering, washing, drying derived products. Benzoyl peroxide content up to 99% of industrial products (two products), mp 102-106 ℃ material consumption fixed: benzoyl chloride (over 95%) 1000kg / t, hydrogen peroxide (30%) 800kg / t. If necessary purification, can be used as alcohols, ****, benzene and other suitable solvent recrystallization. Purposes: for flour improver, oil refining and fiber bleaching, etc., for PVC, polyacrylonitrile polymerization initiator and a crosslinking agent unsaturated polyester, acrylic esters. Used as silicone rubber and fluorine rubber crosslinking agent in the rubber industry. It can be used as a bleaching agent, oxidant, used in chemical production.
