실험 절차

Until HCFC-225cb becomes available in commercial quantities, HCFC-225cb may be prepared by a standard and well-known organic synthesis technique. For example, to prepare 1,3-dichloro-1,1,2,2,3-pentafluoropropane, 2,2,3,3-tetrafluoropropanol, tosyl chloride, and water are reacted together to form 2,2,3,3-tetrafluoropropyl p-toluenesulfonate. Then, N-methylpyrrolidone, potassium fluoride, and the 2,2,3,3-tetrafluoropropyl p-toluenesulfonate are reacted together to form 1,1,2,2,3-pentafluoropropane. Then, chlorine and the 1,1,2,2,3-pentafluoropropane are reacted to form 1,1,3-trichloro-1,2,2,3,2-pentafluoropropane. Finally, isopropanol and the 1,1,3-trichloro-1,2,2,3,2-pentafluoropropane are reacted to form 1,3-dichloro-1,1,2,2,3-pentafluoropropane. A detailed synthesis is set forth below.
