ABSTRACT:
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):in-line-formulae description="In-line Formulae" end="lead"?R1R2M1-R-M2R3R4  (I)in-line-formulae description="In-line Formulae" end="tail"?wherein M1and M2are independently P, As or Sb;R1and R2together represent a bivalent substituted or unsubstituted cyclic aliphatic group whereby the two free valencies are linked to M1; R3and R4independently 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; andR represents a bivalent aliphatic bridging group; and(iii) an acid having a pKaof 3 or less which is in excess over the Group VIII metal.
