METHOD FOR OBTAINING COMPLEX MICROELEMENTAL ADDITIVE TO FEED BASED ON ORGANIC COMPOUNDS OF IRON, MANGANESE, ZINC, COPPER, COBALT

摘要

The invention relates to the field of the chemical industry, in particular to the synthesis of chemical compounds, and concerns the improvement of a method for producing biologically active forms of mixtures of complex compounds of essential trace elements with aspartic acid for use as feed additives for animals, in particular for farm animals. A method of obtaining a composition of complex compounds of trace elements iron (II), manganese (II), zinc (II), copper (II) and cobalt (II) with L-aspartic acid in the molar ratio of the corresponding metal and aspartic acid - 1: 2 and ammonium sulfate for use as an additive in animal feed includes the following stages: the stage of sequential interaction in an aqueous solution of the mono-ammonium salt of L-aspartic acid with zinc, copper, cobalt, iron, manganese sulfate and the stage of water removal.
