Hexafluoro-2-butene (HFO-1336) is a blowing, cooling and solvent agent with low global warming potential. This invention provides the methods for manufacturing the compound, as well as the cis isomer, from readily available raw materials, carbon tetrachloride and ethylene. The trans isomer that is formed in the process can be isomerized to the cis isomer by using a catalyst for isomerization. |
