摘要: Process for the preparation of the (S)-enantiomers of optically active cyanohydrins, in which a reaction mixture of a) an aldehyde or ketone dissolved in an organic, water-immiscible or slightly miscible diluent, b) an aqueous (S)-hydroxynitrile lyase solution and c) a cyanide group donor is stirred in such a way that an emulsion is formed which is maintained up to the end of the reaction by stirring.
