    摘要: A process for separating cis-1,1,1,4,4,4-hexafluoro-2-butene from a first mixture comprising cis-1,1,1,4,4,4-hexafluoro-2-butene and at least one chlorofluoroolefin is disclosed. The process involves the steps of contacting the mixture with at least one extractive agent, to form another mixture, distilling the mixture; and recovering cis-1,1,1,4,4,4-hexafluoro-2-butene substantially free of chlorofluoroolefin.
