The present invention is directed to a method for producing amino acids by reacting halogenated carboxylic acid ester (haloacid esters) with a metal cyanate in the presence of an alcohol and by subsequent acidic saponification of the urethane carbonic acid formed. The method is characterized by the metal cyanate being placed at an elevated temperature in an organic solvent and the other reactants being continuously charged into the mixture over a defined time period.
本发明涉及一种生产氨基酸的方法,该方法通过卤代羧酸酯(卤代酸酯)与金属氰酸酯在醇的存在下反应,随后对形成的氨基甲烷碳酸进行酸性皂化。该方法的特点是将金属氰酸酯置于温度较高的有机溶剂中,其他反应物在规定的时间内连续加入混合物中。
