Abstract

Optically active cyanohydrins are produced by the reaction of an aldehyde with hydrocyanic acid in the presence of D-oxynitrilase (E.C.4.1.2.10). The reaction takes place in an organic solvent which is not miscible with water, but which is saturated with water or an aqueous buffer solution.
