Process for preparing chlorine-containing fluorocarbon compound |
摘要 |
The present invention provides 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): CFnCl3-nCHClCH2Cl, wherein n is 1 or 2, and chlorine-containing fluoropropene compounds represented by Formula (2): CFnCl3-nCCl═CH2, wherein n is 1 or 2, wherein the process includes the step of contacting at least one chlorine-containing compound 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. According to the present invention, the chlorine-containing propane and propene compounds having 1 or 2 fluorine atoms can be prepared by an industrially applicable, simple and effective process. |

1. 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): CFnCl3-nCHClCH2Cl, wherein n is 1 or 2, and chlorine-containing fluoropropene compounds represented by Formula (2): CFnCl3-nCCl═CH2, 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 the molar ratio of 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 liquid phase. |
