Liquid‐phase hydrogen abstraction from chlorinated ethanes by chlorine atoms

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 2 6 7 O and 333OK using a competition technique. The results are compared with gas-phase data.

Radiation‐induced dechlorination of carbon tetrachloride in cyclohexane Solutions. The kinetics of liquid‐phase reactions of trichloromethyl radicals

“…The a values were adjusted to take into account changes in solvent density at the different temperatures. In order to minimize experimental errors in the derivation of the temperature dependence of the k3/(k4)l12 rate constant ratio, expressions (6) and (7) were combined and eq. (8) was used for the least squares treatment of all the experimental data in Table I:…”

“…The C1 atom studies indicate that the activation parameters are different for reactions in the gas and liquid phases [4,6,7]. However, comparative studies on C H 3 radicals, carried out by Mayo [8] and Pryor and coworkers [9], show that the relative reactivities of methyl radicals toward different substrates are the same in the gas phase as in solutions.…”

Gas‐phase hydrogen abstraction from asymmetrically halogenated ethanes by chlorine atoms

“…I t should be noted that while abundant results are available on the gas [ l ] and liquid [9] phase chlorinations of chlorinated ethanes, the corresponding data for the fluorinated compounds are scanty and even contradictory.…”
