بيروكسيد التيرت بوتيل TBHP-70 CAS 75-91-2

Tert-butyl hydroperoxide TBHP-70 is Colourless, mobile liquid consisting of ca. 70 % tert.Butylhydroperoxide, de-sensitised with water. This alkyl-hydroperoxide is used as an initiator for the polymerisation of monomers, e.g. ethylene, vinyl acetate or (meth-) acrylates.Due to its oxidation potential TBHP-70-AQ is used as oxidizing agent in numerous chemical syntheses.
