METHOD FOR MAKING HEXAFLUORO-2-BUTENE

摘要

Hexafluoro-2-butene (HFO-1336) is a low global warming potential blowing agent, refrigerant and solvent. This invention provides a method for making the compound, including the cis-isomer, from the readily available raw materials, carbon tetrachloride and 3,3,3-trifluoropropene. The trans-isomer formed in the process can be isomerized into cis-isomer by the use of an isomerization catalyst.
