FIELD: chemistry.
SUBSTANCE: invention relates to a process for the preparation of an asymmetric ethylenediamine-N,N-di(3-propionic acid) zinc complexate having the structural formula: 
as a starting compound, a zinc complex of asymmetric ethylenediamine-N,N-di(3-propionic acid) dichloride is used, to the aqueous solution of which, with stirring, silver(I) oxide is added at a molar ratio of reactants of 1:1, after which the reaction mass is stirred at room temperature for 3–5 hours, the precipitate of silver chloride is filtered off, the desired product is isolated by evaporation to dryness of the filtered solution, followed by drying at a temperature of 105–110 °C.
EFFECT: invention makes it possible to simplify the method of production and to increase the yield of the desired product.
