| | Benzoyl peroxide Usage And Synthesis |
| Chemical Properties | white powder or crystals | | Usage | vitamin B complex | | Usage | Benzoyl Peroxide is a widely used organic compound of the peroxide family. Benzoyl Peroxide is often used in acne treatments , bleaching and polymerizing polyester and many other uses. | | General Description | White, odorless powder, moderately toxic. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | BENZOYL PEROXIDE is most dangerous when Benzoyl peroxide contains less then 1% water. A moisture content of 3% allowed slow burning only, and at 5% ignition did not occur [McCloskey, C. M. et al., Chem. Abs., 1967, 66, 12613c]. Mixed with a large surplus of water (30% or more) Benzoyl peroxide is relatively safe. In dry form Benzoyl peroxide is a very dangerous material; Benzoyl peroxide will explode spontaneously when heated above melting point (103° C). An explosion which occurred when a screw-capped bottle of the peroxide was opened was attributed to friction initiating a mixture of peroxide Ind organic dust in the cap threads [Lappin, G. R., Chem. Eng. News, 1948, 26, p.3518]. A violent explosion occurred during purification of the peroxide by Soxhlet extraction with hot chloroform [Anon., Sichere Chemiearb., 1976, 28, p. 49]. Benzoyl peroxide is a powerful oxidizer, Benzoyl peroxide ignites readily and burns rapidly. In contact with reducing agents Benzoyl peroxide may ignite by spontaneous chemical reaction. Benzoyl peroxide must be kept in a cool place in isolation, out of the sunlight or sources of heat, avoid shock or friction. Benzoyl peroxide reacts violently with inorganic or organic acids, alcohols, amines, metallic naphthenates and polymerization accelerators (e.g., N,N-dimethylaniline). Explosive or violent reaction on contact with dimethyl sulfide, lithium aluminum hydride or aniline [Bretherick, 5th ed., 1995, p. 1140]. Mixture with carbon tetrachloride and ethylene explodes when exposed to heat [Bolt, R. O. et al., Chem. Eng. News, 1947, 25, p. 1866]. Ignition occurred on contact with methyl methacrylate [MCA Case History No. 996], polymerization of vinyl acetate in ethyl acetate accelerated out of control leading to ignition and explosion [Vervalin, 1973, p. 81]. At 50° C a mixture of dibenzoyl peroxide and charcoal reacts violently producing dense white smoke of benzoic acid, benzene, phenyls and carbon dioxide [Leleu, Cahiers, 1980, 99, p. 279]. |
