Di-tert-butyl peroxide, chemical formula [(CH3) 3CO] 2, is a Organic peroxides. Colorless to yellow transparent liquid with strong oxidizing properties. It is insoluble in water and miscible with benzene and Petroleum ether. The refractive index is 1.3890. The half-life at 100 ° C is 218 hours, 115 ° C 34 hours, and 130 ° C 0.15 hours. Flammable, vapor, and air form explosive mixtures. Irritating to skin, eyes, and respiratory tract.
Tert butyl peroxide (TBHP) and di tert butyl peroxide (DTBP) are important initiators in polymer compositions and are also widely used in organic compositions.
There are many methods for synthesizing tert butyl peroxide and tert butyl peroxide. The synthesis method of Tert-Butyl hydroperoxide includes: oxygen autoxidation; Hydrogen peroxide method; Ozone reaction method, etc. The synthesis methods of Di-tert-butyl peroxide include: alkali catalytic synthesis; Acid catalyzed synthesis method; Metal ion catalysis; Self oxidation method, etc.
In response to the shortcomings of complex operation, long reaction time, and low yield of this method, discussions and improvements were made. The effects of reactant mixing and addition, reaction temperature, reaction time, raw material molar ratio, and reactant concentration on yield were discussed, and more ideal reaction conditions were found. Through the discussion and improvement of the method of preparing Tert-Butyl hydroperoxide and di tert butyl peroxide with Tert-Butyl alcohol and hydrogen peroxide as raw materials and acid as catalyst, the more ideal reaction conditions were found, the operation was simplified, the reaction time was shortened, and the raw materials were saved
