| | 2,3-DICHLOROHEXAFLUORO-2-BUTENE Usage And Synthesis |
| Chemical Properties | clear colorless liquid | | 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. |
