HCl yields from irradiated chloroform are, for doses at least as high as 1.3 x 10/sup 2//sup 1/ ev per gram, greater at 70 plus or minus 4 deg than at 20 deg . The initial G-value at the higher temperature is 31 compared with an average of 11.9 at 20 deg . Chlorine yields from irradiated carbon tetrachloride are slightly smaller at 70 plus or minus 4 deg than at 20 deg . The corresponding G-values are 0.58 and 0.65. The addition of hexachloropthane to carbon tetrachloride prior to irradiation causes a nearly linear decrease in G(/ sub C//sub l//sub 2/) with per cent hexachlorothane. The addition of hexachloroethane to chloroform prior to irradiation causes, at low doses, an increase in G(/sub H//sub C//sub l/) above that in pure chloroform. G(/sub H// sub C//sub l/) in chlorofo rmhexachloroethane mixtures decreases with dose and above approximately 1 x 10/sup 2//sup 1/ ev per gram, becomes less than in pure chloroform. These results are discussed in terms of free radical mechanisms. (auth)
