Abstract

Chloroethanes react with aqueous caustic to yield either elimination or substitution products. The reaction rates were measured for the dichloroethanes, trichloroethanes, tetrachloroethanes, and pentachloroethane between 283 and 353Β°K. The constants of HCl eleminations referring to the rate equation

are given by

all rate constants being in 1./moleΒ·s and R in cal/moleΒ· deg.

With ethyl chloride, 1,1‐dichloroethane, and 1,1,l‐trichloroethane, the elimination is not observed and a slow substitution takes place. The influence of chlorine substituents on both sides of the molecule on mechanism and rate parameters is discussed.

## Abstract HCl elimination from chloroform is shown to be the lowest energy channel for initiation in the thermal conversion of chloroform to CCl~4~, with chlorine gas in the temperature range of 573–635 K. Literature data on this reaction is surveyed and we further estimate its kinetic parameters
