Process for the catalytic hydrogenation of methylolalkanals of the general formula where R<SUP>1 </SUP>and R<SUP>2 </SUP>are each, independently of one another, a further methylol group or an alkyl group having from 1 to 22 carbon atoms or an aryl or aralkyl group having from 6 to 33 carbon atoms, in the liquid phase by means of hydrogen over a hydrogenation catalyst, wherein hydrogen is used in a molar ratio to methylolalkanal of greater than 1.
