Radical Induced Substitution Reaction between Aliphatic Ethers and Tetrachleroethylene

Abstract

Radiation- or erganic peroxide- induced reaetion of tetrachloroethylene with aliphatic ethers was investigated. Uusaturated 1: 1-substitution products were obtained as follows:
When di-t-butylperexide was used, the substitution product ef di-n-propyl ether was obtained with 29% yield. Yields of the substitution products were lowered as the structure of ether changed in the following order:
Di-n-propyl> Di-n-butyl, Ethyl n-butyl> Diethyl> Diisopropyl
When the reaction was initiated by r-ray, G-value of the formatien of substitution product of di-n-propyl ether was 57, and decreased in nearly the same order. Dependency on the dose-rate was not found in this reaction. Apparent activation energies were calculated for some ethers.
