FIELD: updating of process of production of zinc oxalate dihydrate.
SUBSTANCE: product obtained by this method may be used as pigment for production of catalysts of synthesis of inorganic and organic substances, manufacture of ceramic articles and production of oxide and other compounds of zinc. Proposed method includes preparation of reaction solution containing zinc (II) and oxalate, crystallization of target product, separation of sediment from solution and drying the sediment; reaction solution is prepared by mixing the solution of zinc plating process and oxalate-containing reagent; use is made of used solution of zinc plating process and reaction solution containing zinc (II) and oxalate at mole ratio of 1.0: (0.8-3.0) is prepared.
EFFECT: low cost of process at retained purity; possibility of utilization of toxic waste of zinc plating process.
