A process for preparing perfluoroalkanols by hydrogenation of the corresponding aliphatic perfluoroacids. An acid of the formula: CnF2n+1COOH in which n is greater than or equal to 1, is reacted with hydrogen, in the presence of a catalyst based on ruthenium, rhodium, iridium or platinum, under a total pressure of between 1 and 50 bar and in the presence of at least one additive chosen from the group comprising the halide anions and the metal cations of columns IB, IIB, IVA, VA and VB of the periodic table of the elements. |
