PROCESS FOR CATALYTIC CONVERSION OF MIXTURES OF HCFO-1233zd(Z) AND HCFC-244fa INTO HCFO-1233zd(E)

PROCESS FOR CATALYTIC CONVERSION OF MIXTURES OF HCFO-1233zd(Z) AND HCFC-244fa INTO HCFO-1233zd(E)

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 presenceof a catalyst to simultaneously isomerize HCFO-1233zd(Z) to form HCFO-1233zd(E) and dehydrohalogenate...

Zusammenfassung: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 presenceof 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 chromiumtrifluoride, chromium oxyfluoride, or chromium oxide, for example. 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。
