Tert-Butyl Perxoy Benzoate TBPB
Tert-Butyl peroxybenzoate CAS NO. 614-45-9 is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes.
Tert-Butyl peroxybenzoate (TBPB) a chemical compound from the group of peresters. It is often used as a radical initiator in polymerization reactions, such as the production of LDPE from ethylene, and for crosslinking, such as for unsaturated polyester resins.
TBPB is a clear light yellow liquid, which is little soluble in water but well in many organic solvents such as ethanol or phthalate.
As peroxo compound, TBPB contains about 8.16 wt% of active oxygen and has a self accelerating decomposition temperature (SADT) of about 60 °C. The SADT is the lowest temperature at which self-accelerating decomposition in the transport packaging can occur within a week, and which should not be exceeded while storage or transportation.TBPB should therefore be stored between minimum 10 °C (below solidification) an…
