Abstract
A method for conversion of a composition containing HCFO-1233zd(Z) and HCFC-244fa to form HCFO-1233zd(E) by reacting a mixture including HCFO-1233zd(Z) and HCFC-244fa in a vapor phase in the presence of a catalyst to simultaneously isomerize HCFO-1233zd(Z) to form HCFO-1233zd(E) and dehydrohalogenate HCFC-244fa to form HCFO-1233zd(E). The catalyst may be a chromium-based catalyst such as chromium trifluoride, chromium oxyfluoride, or chromium oxide, for example.
