PROCESS FOR THE ISOMERISATION OF C3-7 (HYDRO)(HALO)FLUOROALKENES

摘要

The present invention relates to a process for isomerising a C3-7 (hydro)(halo)fluoroalkene comprising (a) providing a reactor feed stream comprising the C3-7 (hydro)(halo)fluoroalkene; and (b) contacting the C3-7 (hydro)(halo)fluoroalkene with a catalyst comprising alumina to isomerise the C3-7 (hydro)(halo)fluoroalkene, wherein the catalyst has a sodium content of less than about 800 ppm.
