Abstract
Provided is a method for producing glycine, in which on synthesizing glycine from glycinonitrile, glycine can be obtained in a higher yield than that in the conventional method. The present invention relates to a method for producing glycine, including allowing glycinonitrile and water to react with each other in the presence of a cerium compound, optionally adding ammonia thereto, to obtain glycine.
