Chemical properties
Dibenzoyl peroxide is a strong oxidant and is flammable. The nature is extremely unstable, friction, impact, exposure to bright light, high temperature, sulfur and reducing agents, etc., all have the danger of causing fire and explosion. When sulfuric acid is added, it can also cause combustion. In order to prevent explosion, it is generally used when it is diluted to about 20% with insoluble salts such as calcium carbonate, calcium phosphate, calcium sulfate, or talc, bentonite, etc. Or 25-30% water should be injected during storage.
Application
Dibenzoyl peroxide is the most widely used initiator for polymerization, mainly used for solvent polymerization of PVC, polyacrylonitrile, acrylate, vinyl acetate, and graft polymerization of neoprene, SBS and methyl methacrylate. Unsaturated polyester resin curing, initiator and crosslinking agent for plexiglass adhesives, etc. In the rubber industry, it is used as a vulcanizing agent and cross-linking agent for silicone rubber and fluororubber. It can also be used as bleaching agent and oxidizing agent in chemical production. Dibenzoyl peroxide has a whitening effect on wheat flour.
Packaging, storage and transportation
Dried dibenzoyl peroxide commodity is packed in polyethylene-lined paper bags or fiber drums or in polyethylene-lined metal drums. Store in a cool, ventilated, dry, light-proof, independent warehouse composed of non-combustible materials. Set explosion-proof ventilators (explosion-proof holes) in a safe direction. It is strictly forbidden to install electrical equipment or heating facilities indoors. It must be stored and used in the original packaging container, and must not be modified to avoid danger. 30% water should be added during storage to ensure safety. Shading, sealed preservation, must keep a certain amount of moisture during storage. When transporting, the container must be marked with the mark of "organic peroxide", handle it with care, and it is strictly forbidden to knock or bump it, and it is strictly forbidden to store and transport it together with reducing agents and flammable organic substances.
