Patent ID: 8779219

Claim:
A process for preparing at least one chlorine-containing fluorocarbon compound selected from the group consisting of chlorine-containing fluoropropane compounds represented by Formula (1): CF n Cl 3-n CHClCH 2 Cl, wherein n is 1 or 2, and chlorine-containing fluoropropene compounds represented by Formula (2): CF n Cl 3-n CCl═CH 2 , wherein n is 1 or 2, the process comprising the step of contacting at least one chlorine-containing compound as a starting material selected from the group consisting of 1,1,1,2,3-pentachloropropane, 1,1,2,3-tetrachloropropene, and 2,3,3,3-tetrachloropropene with hydrogen fluoride in the absence of a catalyst while heating, wherein a molar ratio of the hydrogen fluoride to the chlorine-containing compound that serves as the starting material is 2 to 100, and wherein at least one chlorine-containing compound is contacted with the hydrogen fluoride in a gas phase.
