The hydrolysis of tert-butyl peroxypivalate in different aqueous buffer solutions (pH = 4, 7 and 9) at 15, 37 and 50 °C was investigated using HPLC-UV. Measurements revealed a fast hydrolysis of  tert-butyl peroxypivalate (half-live: 4 hours) at pH = 4 and 50 °C.  The degradation products of the hydrolysis of tert-butyl peroxypivalate are tert-butyl hydroperoxide and pivalic acid.
