    • PURPOSE: A manufacturing method for 1,1,1,3,3-pentafluoropropane is provided to substitute for CFC and HCFC and to be used for a foaming agent, a coolant, and a detergent not destroying ozone in ozone layer. CONSTITUTION: A process for preparing 1,1,1,3,3-pentafluoropropane by reacting at least one member selected among chlorofluoropropanes and chloropropanes represented by the general formula CX3CH2CHX2 (wherein X represents a fluorine atom or a chlorine atom, provided that not all the X's simultaneously represent fluorine atoms), with antimony chloride fluoride. The 1,1,1,3,3-pentafluoropropane which substitutes for CFC and HCFC and is industrially important as a foaming agent, a refrigerant, a detergent and a propellant which do not destroy ozone in the ozone sphere can be economically prepared in a high yield.
    • 目的:提供1,1,1,3,3-五氟丙烷的制造方法代替CFC和HCFC,并用于发泡剂,冷却剂和不破坏臭氧层臭氧的洗涤剂。 构成:通过使由通式CX3CH2CHX2(其中X表示氟原子或氯原子)表示的氯氟丙烷和氯丙烷中的至少一种使至少一种成分反应制备1,1,1,3,3-五氟丙烷的方法,条件是不是全部 X同时表示氟原子),与氟化锑。 代替CFC和HCFC的作为发泡剂的工业上重要的1,1,1,3,3-五氟丙烷,在臭氧球中不会破坏臭氧的制冷剂,洗涤剂和推进剂可以经济地制备在 高产。
