Process for the manufacture of alpha -hydroxycarboxylic acid amides

摘要

Process for the manufacture of alpha -hydroxycarboxylic acid amides by adding water onto cyanohydrins in an aqueous medium containing 10-60% by weight of the oxo compound on which the cyanohydrin is based, with the aid of a catalyst dissolved in the reaction medium and selected from the group consisting of alkali metal-, alkaline earth metal- and alkylammonium salts of boric acid, at a pH from 7-11.
