Abstract
Cyanohydrin acylates of aldehydes are manufactured by reacting aldehydes with aqueous solutions of cyanides and organic acid chlorides or anhydrides in the molar ratio of aldehyde:cyanide:acid chloride or anhydride of 1:1:1 with deviations of at most only about 10%, optionally in the presence of an inert organic solvent immiscible with water in a one-stage process. The process products are intermediates mainly in the fields of pharmaceuticals and plant protection.
