Title:
PROCESS FOR CATALYTIC CONVERSION OF MIXTURES OF HCFO-1233zd(Z) AND HCFC-244fa INTO HCFO-1233zd(E)
Document Type and Number:
Japanese Patent JP2023159369
Kind Code:
A
Abstract:
To provide a method for producing mixtures containing HCFO-1233zd(Z) and HCFC-244fa that improves overall yields and reduces production cost.SOLUTION: There is provided a method for simultaneous conversion of a composition containing HCFO-1233zd(Z) and HCFC-244fa to form HCFO-1233zd(E), the method including the steps of: providing a composition including HCFO-1233zd(Z) and HCFC-244fa; and reacting the composition in a vapor phase in a reactor in presence of a chromium oxyfluoride catalyst to simultaneously isomerize HCFO-1233zd(Z) to form HCFO-1233zd(E) and dehydrohalogenate HCFC-244fa to form HCFO- 1233zd(E), wherein the reacting step is conducted at a temperature between 200°C and 250°C.SELECTED DRAWING: Figure 2
