Abstract

Polyols are prepared by the catalytic hydrogenation of hydroxyaldehydes in an aqueous liquid in a reactor, the aldehyde concentration in the reaction mixture being maintained below 0.05 gram-equivalents per kg. of reaction mixture at all times during the reaction. The aldehyde concentration is preferably maintained below the amount detectable by the hydroxylamine-hydrogen chloride test throughout the reaction and the pH of the reaction mixture is preferably maintained below 6.5. Numerous suitable hydrogenation catalysts are specified. Examples are given.
