Beschreibung
Zusammenfassung:	The present invention provides a novel process for producing an aminocarboxylic acid salt which is useful as a material for agricultural chemicals and drugs, a chelating agent, a food additive, etc. The process produces an aminocarboxylic acid salt from an aminoalcohol by subjecting the aminoalcohol to an oxida- tive dehydrogenation reaction in the coexistence of an alkali metal hydroxide and/or an alkaline earth metal hydroxide, a copper-containing catalyst and water, and is characterized by performing the reaction while maintain- ing the nickel concentration in the reaction mixture at 40 ppm or less.
