Abstract

The invention relates to a method for production of polyvalent alcohols with low acetal content by catalytic hydrogenation of methylolalkanals of general formula (I), where R1 and R2 independently = a further methylol or C1 - 22 alkyl group or C6 - C33 aryl or aralkyl group in the liquid phase on a hydrogenation catalyst, characterised in that at least one tertiary amine, inorganic base or inorganic or organic acid is added to the hydrogenation feed to adjust the pH value of the hydrogenation product to 7.0 to 9.0.
