    摘要: The invention relates to azeotropic and azeotrope-like mixtures of 1,2,2-trichloro-1,3,3,3-tetrafluoropropane (commonly known as HCFC-224aa, and with the IUPAC name of 2,2,3-trichloro-1,1,1,3-tetrafluoropropane;registry number 139754-75-9) and hydrogen fluoride (hydrofluoric acid), which are useful as intermediates in the production of 1,1,3,3,3-pentafluoropropane (HFC-245-fa) and 1,1,1,2,2,3,3-heptafluoropropane (HFC-227ca).
