采用Adler法合成了四苯基卟啉铁，应用于催化叔丁基过氧化氢（TBHP）分解反应。详细考察了温度、催化剂浓度及TBHP初始浓度等反应条件对分解速率、产物组成的影响。研究结果表明，TBHP分饵是由四苯基卟啉铁配位引发的直链型连锁反应，提高温度或催化剂浓度均能增大分解速率、提高反应对叔丁醇及丙酮的选择性；TBHP分解速率与其初始浓度成正比且在一定浓度范围内基本不变。

Meso- tetraphenylporphyrinatoiron（ Ⅲ ） chloride were prepared by Adler method and used in the catalytic decomposition of tert - butyl hydroperoxide （TBHP）. Including temperature, concentration of catalyst and the initial concentration of TBHP, a wide range of experimental conditions were invested to study their effects on the decomposition rate of TBHP and the composition of products. The results demonstrated that the decomposition were straight - chain reaction which was initiated by the coordination between porphyrin and TBHP. Selectivity of tert -butyl alcohol and acetone, as well as the decomposition rate, increased under a higher temperature or catalyst concentration. Moreover, the decomposition rate was proportional to the initial concentration of TBHP and stayed constant before TBHP reduced too much.
