A comparative CIDNP study of the thermal and photochemical decomposition of acyl benzoyl peroxides PhCO2O2CR (R = methyl and isobutyl) has provided an explanation of the effect of the mode of initiation on the course of the decomposition of this class of peroxides and on the product distribution. The observed variations result from an important decrease (from 10−8 sec to less than 10−10 sec) in the
对酰基苯甲酰过氧化物PhCO 2 O 2 CR(R =甲基和异丁基)的热和光化学分解的比较CIDNP研究提供了引发方式对这类过氧化物和关于产品分销。观察到的变化是由于从热引发转变为光化学引发时,苯甲酰氧基的寿命显着减少(从10 -8秒降至小于10 -10秒)。
