In this work we found that there were five decomposition products of di-t-butyl peroxide at 320 degrees C by GC-MS. The peak area of acetone as a chief product in the thermal decomposition was related to di-t-butyl peroxide concentration in a linear manner. The range was from 22.91 to 114.93 ug (r=0.9997, n=4).
