Abstract

A procedure for the preparation of 5- (3-cyanopropyl) -hydantoin by conversion of 4-cyanobutyraldehyde, in liquid phase, by means of a cyanided reagent, an ammonium reagent and a carbon dioxide reagent, characterized in that during the reaction with the ammonium reagent, the number of moles of the ammonium reagent present, per mole of 4-cyanobutyraldehyde to be converted, is at least two more than double the number of moles of the carbon dioxide reagent present, and therefore minus 2 moles of the ammonium reagent are used in the form of ammonia and/or ammonium hydroxide.
