Abstract:
Azeotropic or azeotrope-like mixtures of 1,3,3-trichloro-3-fluoroprop-1-ene (HCFO-1231zd) and hydrogen fluoride (HF). Such compositions are useful as a feed stock or intermediate in the production of 1,1,1,3,3-pentafluoropropane (HFC-245fa), 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), and 1,3,3,3-tetrafluoropropene (HFO-1234ze).
