Abstract

1. A process for the preparation of alpha-hydroxycarboxylic acid amides from cyanohydrins by catalytic addition reaction with water, characterised in that the addition reaction with water is carried out in an aqueous reaction medium, which contains between 10 and 60% by weight of the oxo compound on which the cyanohydrin is based, in the presence of a catalyst which is dissolved in the reaction mixture and consists of oxygen-containing boron compounds, at a pH value of 7 to 11.
