Characteristics and uses of tert butyl hydrogen peroxide, a chemical product

Tert butyl hydroperoxide (TBHP) is the most commonly used tert alkyl hydroperoxide used as a catalyst for polymerization reactions and as an introduction agent for peroxide groups in substituent reactions. It is a primary organic oxidant (easily explosive at high temperatures). Molecular formula C4H1002 relative molecular weight:, pure product is five color transparent boiling point: about (760mmHg), flash point: (closed blood), (open blood), theoretical active liquid; Melting point:, oxygen content 17.75%, half-life decomposition temperature: (1min), (10h), solubility in water about 12%, weakly acidic, miscible with common organic solvents, tert butyl hydroperoxide TBHP is the most commonly used initiator for free radical reaction, which is characterized by good thermal stability, safe use, easy control, no significant change in its activity within three months, and no need for costly frozen storage. It can be used for lotion polymerization, aqueous phase polymerization In many fields such as curing and grafting polymerization, the performance is superior to that of persulfate, cumene hydroperoxide, and benzoyl peroxide in many aspects.

The decomposition products of TBHP are mainly tert butanol and a small amount of acetone, which are non corrosive and do not require high equipment requirements. Most other initiators will form acidic byproducts. TBHP is also widely used as a polymerization initiator for styrene, acrylic acid, and methacrylic acid. It is a vulcanizing agent of natural rubber and can be used to improve the cetane number of diesel oil. At the same time, it is also a very important intermediate for organic synthesis, especially for its special selectivity and high yield for epoxidation. It is an important intermediate for the production of epoxy propane by the Hakon method. TBHP is also a very useful oxidant. In addition, it can also be used to manufacture adhesives and drying agents for unsaturated melamine tree vinegar coatings.
