    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.

    Abstract: A process is described wherein otherwise unusable by-products from a process for the manufacture of trans HCFO-1233zd(E) are converted to a valuable product by introducing them into a process for the production of HFC-245fa. The process includes the catalytic hydrofluorination of a reaction mixture comprising the HCFO-1233zd production by-products.
