Some effects of temperature and of various solutes (Cl/sub 2/, Br/sub 2/ , I/sub 2/, O/sub 2/ and C/sub 2/Cl/sub 4/) on the Co/sup 60/ gamma-ray -induced decomposition of liquid CCl/sub 4/ were investigated. Cl/sub 2/ and C/sub 2/Cl/ sub were the only detectable products in pure, air-free, dry CCl/sub 4/. O/sub 2/ accelerated and C/sub 2/Cl/sub 4/ inhibited the decompositi on. Scavenger studies indicated that an abundance of CCl/sub 3/ radtials were formed, most of which back-reacted to form CCl/sub 4/ at measurable Cl/sub 2/ concentrations. No other radicals were detected. A rapid initial reaction with a temperature coefficient of about 3%/ deg C was observed above room temperature. This reaction was strongly inhibited by Cl/sub 2/ to a terminal rate which was independent of temperature. A diffusion-limited free-radical mechanism involving thermal CCl/sub 3/-radicals and excited CCl/sub 3/-radicals is proposed to rationalize the effects of temperature and Cl/sub 2/. (auth)
