ditertbüülperoksid

Ditertbutyl peroxide, often abbreviated as DTBP, is an organic compound with the chemical formula (CH3)3COOC(CH3)3. It is a peroxide, meaning it contains an oxygen-oxygen single bond, which is a relatively weak and reactive functional group. DTBP is a colorless liquid at room temperature. It is synthesized through the reaction of tert-butyl alcohol with hydrogen peroxide in the presence of an acid catalyst.

The primary use of ditertbutyl peroxide is as a radical initiator in polymer chemistry. When heated, the O-O bond in DTBP breaks homolytically, forming two tert-butoxy radicals. These radicals can then initiate the polymerization of various monomers, such as styrene and acrylates, leading to the formation of polymers. DTBP is favored in some applications due to its relatively low decomposition temperature compared to other initiators, allowing for polymerization at milder conditions. It is also used as a crosslinking agent for certain polymers, improving their mechanical properties.

Distertbutyl peroxide is considered a hazardous substance. It is flammable and can decompose explosively if heated rapidly or subjected to shock. It is also an irritant to skin and eyes. Proper handling and storage procedures are essential to prevent accidents. Due to its reactive nature, it is typically stored in cool, well-ventilated areas away from heat sources and incompatible materials.
