Brief introduction:
TBHP is a volatile, yellowish transparent liquid, which is the most commonly used initiator of free radical reaction. It is characterized by its good thermal stability, safe use and easy control. Its activity does not change significantly within three months under 50 degrees Celsius, and does not require higher cost of cryopreservation. It can be used in many fields such as emulsion polymerization, water phase polymerization, curing and polymerization. It is superior to over two sulfate in many aspects. Cumene, hydrogen peroxide and benzoyl peroxide. The decomposition products of TBHP are mainly tert butyl alcohol and a small amount of acetone, which are non corrosive and have low requirements for equipment. Most of the other initiators will form acidic by-products. TBHP is also widely used as polymerization initiator of polystyrene, acrylic acid and meth-acrylic acid. TBHP is the vulcanizing agent of natural rubber. It can be used to improve the cetane number of diesel oil. At the same time, it is also a very important intermediate in organic synthesis. It has special selectivity and high yield for epoxidation. It is a very important oxidant.
