AZEOTROPE AND AZEOTROPE-LIKE COMPOSITIONS USEFUL FOR THE PRODUCTION OF HALOOLEFINS

摘要

The present invention pertains to ternary azeotrope and azeotrope-like composition including 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), HF, and either 1,1,2,3-tetrachloropropene (TCP) or 1,1,1,2,2-pentafluoropropane (HFC-245cb). The present invention also relates to binary azeotropes of 2,3,3,3-tetrachloropropene and HF. Such azeotropic and azeotrope-like compositions are useful as intermediates in the production of 2,3,3,3- tetrafluoropropene (HFO-1234yf).
