(57) [Summary] [Structure] Fluorotrichloromethane and tetrafluoroethylene are reacted in the presence of a catalyst in a reaction solvent to give 1, 1,1,2,2-pentafluoro-3,3,3-trichloropropane and 1,1,2,2,3-pentafluoro-1,3, A method for producing 3-trichloropropane, characterized in that the concentration of fluorotrichloromethane in the reaction liquid during the reaction is kept at 3% by weight or less. According to the method of the present invention, R-215ca and cb can be obtained in high yield and high selectivity. Also, It is economical because it is possible to take a continuous reaction form. |
