The rate constants of liquid‐phase hydrogen abstraction by chlorine atoms from 1,2‐C 2 H 4 Cl 2 relative to those of addition to C 2 HCl 3 and to C 2 Cl 4 and to that of hydrogen abstraction from cyclohexane have been measured between 250 and 345°K. Assuming a zero activation energy for the addition reactions permits one to calculate the corresponding values for the liquid‐phase hydrogen abstraction from the chlorinated ethanes. These values are discussed and compared with the gas‐phase data.
