  • Patent number: 9926244
    Abstract: The present disclosure provides separation processes that use azeotropic or azeotropic-like compositions of 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) that allow for improved recovery rates of 1-chloro-3,3,3-trifluoropropene during or after manufacturing processes. Such recovery or separation processes can utilize the unique properties of azeotropic or azeotropic-like composition with various combinations of separation techniques (e.g., distillation and decanting) that yield highly pure compositions of 1-chloro-3,3,3-trifluoropropene and simultaneously offer high yields of 1-chloro-3,3,3-trifluoropropene. Such highly pure compositions of 1-chloro-3,3,3-trifluoropropene may find useful applications in polymer technology as monomers or comonomers.
