METHOD FOR PRODUCING ISOMERS OF 1,2-CHLORO-2,3,3-TRIFLUORO-1-PROPENE (HCFO-1233yd)

Abstract

Production of HCFO-1233yd blends with broad range of Z-isomer and/or E-isomer is achieved through isomerization reactions under suitable reaction conditions. Methods of producing cis-HCFO-1233yd(Z) may include providing a reactant stream containing at least 50% HCFO-1233yd(E), vaporizing at least a portion of HCFO-1233yd(E) in the reactant stream, converting at least a portion of HCFO-1233yd(E) to HCFO-1233yd(Z) in a reactor, and separating and recovering a composition comprising HCFO-1233yd(Z) or a mixture of HCFO-1233yd(E) and HCFO-1233yd(Z). The reaction may be conducted in the presence of a catalyst.
