General description

The pure cis- and trans-isomers of 2,3-dichlorohexafluoro-2-butene were separated when 2,3-dichlorohexafluoro-2-butene (mixture of cis and trans) reacted with dry diglyme and sodium borohydride and was hydolyzed. The isomers were purified by preparative vapor phase chromatography technique.
