催化氟化合成1,1,1,2—四氟乙烷

论述了三氯乙烯路线气相催化氟化合成１，１，１，２－四氟乙烷的催化剂、载体的制备方法以及氟化氢与三氟乙烯、ＨＣＦＣ－１３３ａ反应的特点，认为控制生成ＨＣＦＣ－１３３ａ的反应热、提高ＨＦＣ－１３４ａ的选择性是反应研究的关键。建议开发具有高活性、高选择性的氟化物载体负载的低铬或无铬催化剂。

Synthesis of 1,1,1,2-tetrafluoroethane by Gasous Phase Catalytic Fluorination

Research on preparation of catalysts and carriers.characteristic of HF reaction with trichloroethylene and HCFC-133a for synthesis of HCF-134a from the route of trichloroethylene by gasous phase catalytic fluorination were reviewed.We propose that controlling the reaction heat of producing HCFC-133a and improving the selectivity to HFC-134a is a key to investigation of the reaction.It is suggested that fluoride compounds supported metal catalysts containing less Cr~(3+) or other metals with higher activity and selectivity should be developed.
