Description and Uses
Tert-Butyl peroxybenzoate (TBPB) is an organic compound with the formula C6H5CO3CMe3 (Me = CH3). TBPB, a pale yellow, is exclusively encountered as a solution in solvents such as ethanol or phthalate. It is an ester of peroxybenzoic acid and the most widely produced perester.
Tert-Butyl peroxybenzoate is used for elevated temperature curing of polyesters and to initiate polymerization reactions. It could used as a Polymerization initiator for polyethylene, polystyrene, polyacrylates, and polyesters. It is also used as a chemical intermediate.
