2170-08-3, also known as di-tert-butyl peroxide, is an organic peroxide widely used as an initiator for free radical polymerization and copolymerization of a variety of monomers. The chemical formula for 2170-08-3 is (C4H9)2O2 and its molecular weight is 221.20 g/mol. It is a white to light yellow crystal or powder with a faint pungent odor.
2170-08-3 is a strong oxidizing agent and is highly reactive, thus it is usually sold in solution form. It is combustible and should be kept in cool, dry, dark and well-ventilated areas at temperatures below 40°C. Transportation of 2170-08-3 requires special care to ensure it is not exposed to light or heat.
2170-08-3 is used as an initiator for the polymerization of a variety of monomers including styrene, acrylonitrile, ethylene, propylene, butadiene, and other vinyl monomers. Its primary application is in the production of styrene-acrylonitrile (SAN) copolymers. It is also used in the production of polyvinylchloride (PVC), ethylene-vinyl acetate (EVA) and polyethylene (PE).
2170-08-3 has a low solubility in water and is soluble in many organic solvents such as acetone, dioxane and toluene. It is relatively stable when stored in the absence of light and heat. However, it is highly sensitive to shock and can be explosive when heated or subjected to flame. It should be handled with extreme care and protective clothing should be worn when handling this substance.
2170-08-3 is an important industrial chemical and has numerous applications in the plastics and rubber industry. It is used as a catalyst in the production of polyurethanes and other polymers and is also used as a curing agent for epoxy resins. It is used as a bleaching and oxidizing agent in the textile and dye industries. It is also used to produce explosives and other pyrotechnic materials.
