Di-tert-butyl peroxide
Di-tert-butyl peroxide or DTBP is an organic compound consisting of a peroxide group bonded to two tert-butyl groups. It is one of the most stable organic peroxides, due to the tert-butyl groups being bulky. It is a colorless liquid.[1]
Reactions
The peroxide bond undergoes homolysis at temperatures above 100 °C. For this reason di-tert-butyl peroxide is commonly used as a radical initiator in organic synthesis and polymer chemistry. The decomposition reaction proceeds via the generation of methyl radicals.
- (CH3)3COOC(CH3)3 → 2 (CH3)3CO•
- (CH3)3CO• → (CH3)2CO + Template:Chem/link
- 2 Template:Chem/link → C2H6
DTBP can in principle be used in engines where oxygen is limited, since the molecule supplies both the oxidizer and the fuel.[2]
Safety
DTBP is an irritant to the nose, eyes, and skin. It is also flammable, and can explode unpredictably at high (≈150 °C) temperatures.[3]
