METHOD FOR PRODUCTION OF 1,1,1,3,3-PENTAFLUOROPROPANE Russian patent published in 1996 - IPC

Abstract RU 2065430 C1

FIELD: production of cooling agent. SUBSTANCE: method is carried out by interaction of 1,1,1,3,3-pentachloropropane with hydrogen fluoride. The process takes place at 50-160 C and pressure 5-25 kgf/cm2 in the presence of catalyst. Said catalyst contains antimony pentachloride and hydrogen fluoride, their molar ratio SbCL5/HF being (1:70)-(1:1.8). Capacity of said catalyst is 0.08-1 kg of 1,1,1,3,3-pentachloropropane per 1 kg of SbCL5 per hour. EFFECT: increases yield of desired product, simplifies the process. 2 tbl
