Abstract

1427254 1,1-Dihydro-perfluoroalkanols HOECHST AG 9 May 1973 [9 May 1972] 22032/73 Heading C2C 1,1-Dihydro-perfluoroalkanols of the general formula wherein n is an integer of 6 to 12, are prepared by hydrogenation of a perfluoroalkanoic acid of general formula in a container of "stainless steel" i.e. an iron alloy containing Cr and/or Ni generally with small amounts of C, e.g. up to 1À7 wt. per cent based on Fe, in the presence of a ruthenium catalyst and 1À2-2 moles of a compound of general formula wherein m is an integer of 6 to 12, x is an integer from 1 to 4 per mole of perfluoroalkanoic acid of Formula II, at a hydrogen pressure of 5 to 300 atmospheres and at 100‹ to 250‹ C. Preferably 1 to 10% by weight of Ru based on the weight of carbon and on the weight of perfluoroalkanoic acid is present. In the examples 1,1-dihydroperfluoro - octanol - 1 and 1,1 - dihydroperfluoro-(7-methyl-octanol) are prepared.
