Studies on the telomerization of ethylene with carbon tetrachloride : I. Kinetics of the telomerization initiated by azo-bis-isobutyronitrile

Abstract

The telomerization of ethylene with carbon tetrachloride initiated by AIBN (azo-bis-isobutyronilrile) has been investigated kinetically. Reactions were carried out continuously in a tubular coil reactor at temperatures between 85° and 100℃ at constant pressure of 150kg/cm^2. It has been shown that the reaction rate of ethylene follows the rate equation : -d[C_2H_4]/dt/=k'[C_2H_4][AIBN]^1/2. Chain transfer constants of the telomer radicals to carbon tetrachloride were calculated as follows: C_1=0.1, C_2=2.1, C_3=3.8 and C_4=5.2.
