276 g (1 mol) of 2,2,3,3,4,4-hexafluorocyclopentyl cyclohexyl ether from Step 2 are added dropwise to 300 ml of concentrated sulphuric acid until the evolution of gas has ceased, and the cleavage product is distilled off at 130°-140° C. The mixture of the desired alcohol and cyclohexene is redistilled. In this manner, distillation gives 2,2,3,3,4,4-hexafluorocyclopentanol.
