Tertiary butyl perbenzoate

Organic peroxides, like benzoyl peroxide, 2-4, dichlorobenzoyl peroxide, tertiary butyl-perbenzoate are used for natural and synthetic rubbers. 

A variety of dialkyl peroxides and tertiary butyl perbenzoate lead to high efficiency of cross-linking reactions in gum rubber, but only di-tertiary butyl and dicurnyl peroxides are capable of curing compounds containing reinforcing black fillers. Of these two, the former has the serious drawback of volatility, and hence very low efficiency. 

Catalyst (curing agent) Initiate the curing reaction at elevated temperature Benzoyl peroxide (e.g., tertiary butyl perbenzoate)... 

Thin layer chromatography has also been applied to reactive organic peroxide residues such as tertiary butyl perbenzoate and benzyl peroxide in polystyrene (Method 34). 

The second-stage cross-linking (cure) reaction is initiated by organic peroxides MEK peroxide for room-temperature cure, and benzoyl peroxide or t-butyl perbenzoate or other stabler peroxides for higher-temperature cure processes. Peroxide action may be speeded by heat and/or activators such as cobalt soaps and tertiary amines. (Nonchemists are apt to use the terms catalyst and activator ratber loosely, which can he confusing or even dangerous in practice.)... 

The oxidative epoxidation reactions of unsaturated siliconorganic compounds by perbenzoic acid in chloroform and tetrachloromethane proceeds significantly r idly than another solvents, though by using less active solvents (ether, tetrahydrofurane) is possible exception of secondary reactions. In addition it was shown [18] that oxidative epoxidation of vinyl containing sili-conoiganic compounds by tertiary-butyl aleohol in the presence of Mo(CO)g in benzene solution at 40°C epoxy deievatives is abot 60-70%. 

The reaction of peroxyesters, hydroperoxides or peroxides, which are more storage stable than BP, with tertiary amines is generally too slow to give a sufficiently rapid cure for acrylic resins. Composite mixes containing t-butyl perbenzoate, -butyl hydroperoxides or dicumyl peroxide-tertiary amines do not harden for days. Many other redox systems have been suggested for vinyl polymerizations, only a few have been employed in dental resins. Substitution of 2 toluene sulfinic acid or sulfinic acid derivatives for tertiary amines yields colorless products (38-42). Most of these compounds have poor shelf-life. They readily oxidize in air to sulfonic acids which do not activate polymerization. Lauroyl peroxide in conjunction with a metal mercaptide (such as the zinc hexadecyl mercaptide) and...
