Abstract
The hydrogen abstraction from the chlorinated ethanes by chlorine atoms has been investigated in the liquid phase. Rate constants relative to that for hydrogen abstraction from chloroform have been measured between 267ยฐ and 333ยฐK using a competition technique. The results are compared with gasโphase data.

## Abstract The hydrogen abstraction from asymmetrically fluorinated and chlorofluorinated ethanes by chlorine atoms has been investigated in the gas phase between 264 and 333ยฐK using the competition method. Arrhenius parameters for the reaction on both sites of the molecules are discussed.
The kinetics of chlorine atom abstraction from the chloromethanes (CM)CC14, CHCl3, and CHBCl2 by radiolytically generated cyclohexyl radicals has been studied in the liquid phase by a competitive method. The halogen abstraction data have been put on an absolute basis by comparing the rates of the me

The kinetic isotope effect for the abstraction of hydrogenideuterium from dimethylnitramine and dimethylnitramine-ds by chlorine atoms has been studied in the temperature range 273-353 K. The rate constant ratio k H / k D is given by the Arrhenius expression, k H / k o = (0.92 t-0.07)exp(286 ? 250/R
