    摘要: A process for producing primary alcohols from secondary alcohols and/or tertiary alcohols and/or ketones, wherein the process comprises reacting a compound selected from a secondary alcohol, a tertiary alcohol, a ketone, or mixtures thereof, with carbon monoxide and hydrogen in the presence of a catalyst based on: (i) a source of Group VIII metal, (ii) a bidentate ligand having the general formula (I): R1R2M1-R-M2R3R4  (I) wherein M1 and M2 are independently P, As or Sb; R1 and R2 together represent a bivalent substituted or unsubstituted cyclic aliphatic group whereby the two free valencies are linked to M1; R3 and R4 independently represent a substituted or unsubstituted hydrocarbyl group, or together represent a bivalent or non-substituted cyclic group whereby the two free valencies are linked to M2; and R represents a bivalent aliphatic bridging group; and (iii) an acid having a pKa of 3 or less which is in excess over the Group VIII metal.
