Abstract

The invention relates to the synthesis of hydrogenperfluoroalkanes R.sub.F H, R.sub.F denoting a perfluoroalkyl radical containing 2 to 20 carbon atoms, by reaction of the corresponding perfluoroalkyl iodide R.sub.F I with an alkali metal hydroxide. The use of methanol as solvent allows the formation of tars to be avoided, an almost total conversion of R.sub.F I and an R.sub.F H of excellent purity to be obtained, and the alkali metal iodide by-product to be recovered easily.
