反応手順

40 g (0.2 mol) of 1,1,1,4,4,4-hexafluoro-2-chloro-2-butene were hydrogenated in 300 ml of ethanol in the presence of 12 g of potassium hydroxide and 24 g of Raney nickel in the pressure range of from 20 to 40 bar and at a temperature from 20 to 100° C. The solid components were filtered off, the solvent was extracted with water, and the organic phase was separated and purified by distillation to give 15.5 g (47% of theory) of 1,1,1,4,4,4-hexafluorobutane. The boiling point was 25 to 27° C. at 1013 mbar.
