    • A process for the hydrogenation of a reactant selected from: (a) a 5- or 6-membered lactone that is substituted at the ring-closing carbon atom and has a proton at a carbon atom adjacent to the ring-closing carbon atom; (b) an ester of a carboxylic acid having a gamma- carbonyl group and a proton at a carbon atom adjacent to the carbon atom of the carbonyl group; and (c) a carboxylic acid having a gamma-carbonyl group and a proton at a carbon atom adjacent to the carbon atom of the carbonyl group, which process involves contacting the reactant with a catalyst in the presence of hydrogen, at a temperature from 100 to 3500C and a pressure from 1 to 150 bar (absolute), provided the pressure is low enough to avoid condensation of the heaviest feed component at the temperature chosen, and wherein the catalyst is a weakly acidic heterogeneous catalyst comprising a hydrogenating metal.
