실험 절차

960 g of 1,2-dichloro-1,1,4,4,4-pentafluorobutane were added dropwise to a mixture of 3 1 of distilled tetramethylene sulphone and 830 g of dried potassium fluoride at 190° C. and 1,1,1,4,4,4-hexafluorobut-2-ene was distilled off as it was formed. The product thus obtained was redistilled to give 650 g of 1,1,1,4,4,4-hexafluorobut-2-ene having a boiling point of 8° C at atmospheric pressure.
