Conclusions
-
1.
The dielectric constant of the medium and the solvating ability of the solvents (n-C6H14, C6H6, t-C4H9OH, i-C3H7OH, CH3OH) have little effect upon the total rate and rati of telomerization products of ethylene and propylene with CCl4 at 100–105‡.
-
2.
The sharp increase in the yield of tetrachloropropane and the total rate of the process, observed in certain cases when the telomerization of ethylene with CCl4 is conducted in autoclaves in the presence of alcohols with labile α-hydrogen, is always accompanied by the appearance of Fe compounds in the reaction mixture. The basic cause of such effects is the joint accelerating influence of alcohol and iron compounds formed in its presence as a result of corrosion upon chain transfer with CCl4.
