进行了过氧化月桂酰(1)在脱氧的苯中的分解动力学研究,当起始浓度0.1～0.2克分子·升-1,温度30℃、40℃时,1不是严格地按一级反应分解的.在50℃下起始浓度0.04～0.34克分子·升-1时,实验结果符合一级加二分之三级的反应规律:-(da/dt)=k1a+k1a3/2.求出的自发分解速率常数k1=0.0115小时-1,诱导分解速率常数k1=0.014克分子-1.2·升1/2·小时-1.

We have investigated the decomposition of lanroyl peroxide, 1 in benzene at 30℃, 40℃ and 50℃ and followed the iodometrioally. With an initial concentration of 1 between 0.1 to 0.2 M and at to ature of 30℃ or 40℃, a first-order plot could be obtained, but the slope inorea,sed with the increase of initial concentration (Fig. 1) indicating that some induced decomposition was involved.
