Abstract

PURPOSE: To obtain glycollonitrile, the discolocation and decomposition of which at higher pH range are remarkably suppressed, at relatively lower reaction temperature in higher product yield by reacting formaldehyde with hydrogen cyanide in the presence of a small amount of acid phosphite ion in an aq. medium.
