An efficient flow process for the degradation of Freon-114 to carbon tetrafluoride has been developed. Various operating variables were studied under laboratory conditions, and fluorination of Freon-114 was found to proceed exclusively by substitution at temperatures below 450 deg C and by degradation at temperatures above 500 deg C. The difference in mechanism is explained on the basis of greater temperature dependence for the degradation process than for the substitution reaction. lndirect evidence for a free radical reaction mechanism, based on kinetic studies of the substitution reaction between 400 and 450 deg C, was obtained. Low-temperature (225 to 250 deg C) Freon-115--fluorine substitution appears to involve surface reactions. (auth)
