PROCESS FOR CATALYTIC CONVERSION OF A MIXTURE OF 1233zd (Z) AND 244fa TO 1233zd (E)

The present application relates to a process for the catalytic conversion of a mixture of 1233zd (Z) and 244fa to 1233zd (E). The present invention provides a process for converting a composition comprising HCFO-1233zd (Z) and HCFC-244fa to form HCFO-1233zd (Z) by reacting a mixture comprising HCFO-1233zd (Z) and HCFC-244fa in the gas phase in the presence of a catalyst to simultaneously isomerize the HCFO-1233zd (Z) to form HCFO-1233zd (E) and dehydrohalogenate the HCFC-244fa to form HCFO-1233zd (E). The catalyst may be a chromium-based catalyst, such as chromium trifluoride, chromium oxyfluoride, or chromium oxide. 本申请涉及用于将1233zd(Z)和244fa的混合物催化转化为1233zd(E)的方法。本发明提供了一种用于通过在催化剂的存在下使包含HCFO-1233zd(Z)和HCFC-244fa的混合物在气相中反应以同时使HCFO-1233zd(Z)异构化以形成HCFO-1233zd(E)并使HCFC-244fa脱氢卤化以形成HCFO-1233zd(E)，从而转化包含HCFO-1233zd(Z)和HCFC-244fa的组合物以形成HCFO-1233zd(E)的方法。该催化剂可以是基于铬的催化剂，诸如三氟化铬、氟氧化铬或氧化铬。
