ABSTRACT:
A process for producing glycinonitrile under substantially adiabatic reaction conditions by reacting in a tubular reactor hydrogen cyanide, formaldehyde and ammonia. The excess ammonia is flashed off and the remaining solution volatiles are evaporated and condensed to product. The resulting glycinonitrile can be saponified to the alkali metal glycinate, from which glycine can be prepared.
