Abstract

Method for preparing acrolein cyanohydrins The present invention relates to an improved method for preparing acrolein cyanohydrins from hydrocyanic acid and the corresponding acroleins. The method is characterized in that the acrolein cyanohydrins obtained have a very low hydrocyanic acid content or are free of hydrocyanic acid 5 and are therefore particularly well suited as intermediates for the synthesis of glufosinates.
