摘要: Disclosed is a reactor for producing a hydrofluorocarbon compound by reacting a chlorinated organic compound with hydrogen fluoride in liquid phase in the presence of an antimony chlorofluoride catalyst, comprising an inner wall B lined with a polytetrafluoroethylene (PTFE) resin, and an outer wall A. A space G of 2 to 10 mm is formed between the inner wall and the outer wall, and maintained by spiral baffles. Additionally, a plurality of vent holes with diameter of 2 to 5 mm are formed, at regular intervals of 150 to 300 mm, on the whole inner wall of the reactor. The reactor is advantageous in that the PTFE resin lined on the inner wall of the reactor is not degraded, thereby prolonging a reactor's life span and easily supplying heat to the reactor.

摘要: Disclosed is a method of producing difluoromethane (HFC-32), which comprises firstly reacting methylene chloride with hydrogen fluoride in gas phase at 280 to 340null C. in the presence of a fluorinated catalyst to produce chlorofluoro methane, and secondly reacting the chlorofluoro methane with hydrogen fluoride in liquid phase at 60 to 80null C. in the presence of an antimony chloride catalyst. The method is advantageous in that HFC-32 is produced in high yield under mild reaction conditions using a relatively small amount of energy.
