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 gasโ€phase data.

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
