摘要： A process for producing glycine by the reaction of glycolonitrile with carbon dioxide and ammonia in the presence of water, which comprises the steps of conducting a preliminary reaction of glycolonitrile, with carbon dioxide, ammonia and water at 80 to 120 °C for 0.5 to 1 hr, conducting a main reaction at 150 to 200 °C, separating glycine thus formed from the reaction mixture, and recycling the remaining mother liquor to the reaction system comprising glycolonitrile, carbon dioxide, ammonia and water to conduct the preliminary and/or main reaction.
