| titleOfInvention | Method for stabilizing 1,1-dichloro-2,2,2-trifluoroethane |
| abstract | PURPOSE: To stabilize the title compound by adding styrene or a derivative thereof to the title compound, thereby suppressing the generation of 1- chloro-2,2,2-trifluoroethane which is a decomposition product of the title compound. n CONSTITUTION: A compound such as styrene, vinyltoluene, α-methylstyrene, p-isopropenyltoluene or p-isopropenyl-o-xylene, expressed by the formula (R 1 to R 4 are H or 1-3C hydrocarbon group) is added to 1,1-dichloro-2,2,2- trifluoroethane (R123) at an amount of ≥0.001wt.%, preferably 0.01-5wt.% based on R123. Thereby, generation of 1-chloro-2,2,2-trifluoroethane which is a decomposition product of R123 and is suspected as a carcinogenic substance is suppressed to provide a stabilized R123 which is usable for foaming agent, refrigeration medium, aerosol, and solvent, etc., as a substitute for trichlorofluoromethane. n COPYRIGHT: (C)1992,JPO&Japio |
