Summary: | 1322614 Halogenated methanes FARBWERKE HOECHST AG 2 Aug 1971 [3 Aug 1970] 36258/71 Heading C2C Compounds of formula CF 3 Cl, CF 2 Cl 2 , CFCl 3 and CCl 4 , are prepared by reacting one or more aromatic hydrocarbons and/or chloro-substitution products thereof, with Cl 2 and HF, at a temperature of 400-800‹ C. and a pressure of 50-800 atm. gauge. Exemplified hydrocarbons are benzene and monochlorobenzene. The reactor may have a preliminary reaction zone, at a temperature less than 400‹ C., containing a liquid sump of hexachlorobenzene, into which the reactants are pumped, preferably in the liquid state. |
