实验步骤: 200 g of 2-chloro-1,1,1,4,4,4-hexafluorobutane were added dropwise to a mixture of 195 ml of distilled tetramethylene sulphone and 87 g of dried potassium fluoride at 190° C. and the 1,1,1,4,4,4-hexafluorobut-2-ene which formed was continuously distilled off. 135 g of 1,1,1,4,4,4-hexafluorobut-2-ene were obtained.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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. 1,1,1,4,4,4-hexafluorobut-2-ene was distilled off as it was formed The product thus obtained was redistilled

实验步骤: In a 20 1 stainless steel autoclave, which had previously been conditioned using 10% strength nitric acid and was equipped with closed circuit heating and an anchor stirrer, 10.0 kg of 1,1,1,4,4,4-hexafluorobutene were heated from 0 to 30 C. over a period of 10 minutes in the presence of 250 g of catalyst (5% by weight of metallic palladium on activated carbon) at a pressure of 20 bar of hydrogen. After reaching this temperature, the hydrogen consumption was compensated for by repeated pressurization with fresh hydrogen at pressures between 20 and 30 bar. After about 2.5 hours the conversion was 87%. 1,1,1,4,4,4-Hexafluorobutane had been formed in a yield of greater than 99% of theory. was equipped with closed circuit heating the hydrogen consumption
