    • A process for dehydrating a hydrofluorocarbon or hydrochlorofluorocarbon, which can be done by simple equipment, and a continuous process of producing 1,3,3,3-tetrafluoropropene using the dehydration process. The dehydration process includes cooling the hydrofluorocarbon or hydrochlorofluorocarbon in gaseous form containing water with a heat exchanger, thereby condensing and liquefying the hydrofluorocarbon or hydrochlorofluorocarbon while freezing and solidifying the water. The 1,3,3,3-tetrafluoropropene production method includes a first step for fluorinating 1-chloro-3,3,3-trifluoropropene with hydrogen fluoride to obtain a mixture of 1,3,3,3-tetrafluoropropene, unreacted 1-chloro-3,3,3-trifluoropropene, hydrogen fluoride, hydrogen chloride and by-products, or dehydrofluorinating 1,1,1,3,3-pentafluoropropane to obtain a mixture of 1,3,3,3-tetrafluoropropene, unreacted 1,1,1,3,3-pentafluoropropane and by-products, a second step for removing acidic components, a third step for dehydrating the 1,3,3,3-tetrafluoropropene by the above dehydration process, and a fourth step for purifying the 1,3,3,3-tetrafluoropropene by distillation.

    • The invention relates to a method for purifying a crude 1,1,1,3,3-pentafluoropropane (HFC-245fa) containing HFC-245fa and 1-chloro-3,3,3-trifluoro-trans-1-propene (HCFC-1233zd(t)), by distillation. This method is characterized in that the distillation is conducted in the presence of a solvent having a boiling point which is higher than that of HCFC-1233zd(t), thereby to substantially remove HCFC-1233zd(t) from the crude HFC-245fa. This solvent may be selected from carbon chlorides, chlorohydrocarbons, fluorochlorohydrocarbons, saturated hydrocarbons, and mixtures thereof. With the use of this solvent, it becomes possible to substantially easily separate HFC-245fa from HCFC-1233zd(t).
    • 本发明涉及一种纯化含有HFC-245fa和1-氯-3,3,3-三氟 - 反-1-丙烯(HCFC)的粗制1,1,1,3,3-五氟丙烷(HFC-245fa)的方法 -1233zd(t))。 该方法的特征在于在沸点高于HCFC-1233zd(t)的溶剂的存在下进行蒸馏,从而从粗HFC-245fa基本上除去HCFC-1233zd(t)。 该溶剂可以选自氯化碳,氯代烃,氟氯烃,饱和烃及其混合物。 通过使用该溶剂,可以基本上容易地将HFC-245fa与HCFC-1233zd(t)分离。
