CL4 C07c 59/105 C25B 3/12 Inventors: Zbigniew Ratajewioz, Józef Sawa The holder of the patent: Lublin University of Technology, Lublin (Poland) METHOD OF OBTAINING IRON GLUCONIAFLUE OF IRON No. 140 484 is a method of obtaining ferrous gluconate. It consists in conducting an electrochemical reaction with the use of iron or low-carbon steel electrodes in a solution of gluconic acid and passing an electric current in an alternating way * As an electrolyte, a mixture of water with an organic solvent, especially acetone, in the amount of 0.5 - 50% by weight of organic solvent and 2 - 50% by weight of gluconic acid, and the density of the anode current maintained in the process is 0.2 - 4 amps / dm. The process is carried out at an elevated temperature in a non-oxidizing atmosphere, especially made of COp, H2 and / or, for example, in the course of further research on the preparation of ferrous gluconate, it was found that the use of an organic solvent in an aqueous-organic solution of gluconic acid in anodic digestion Ferrous methanol and / or its mixture with acetone or ethanol has the advantage of significantly accelerating the process and obtaining ferrous gluconate of considerable purity in one operation. Two metallic iron electrodes and 0.5 dm3 of a 1 molar gluconic acid solution in a water-aethanol-tanol solvent with a methanol content of 10% were introduced into a closed electrolyser with a capacity of 0.6 dm3, through which the nitrogen stream flows. ethanol 10%. Anodic digestion of iron was carried out at the temperature of 323 K with a constant current of 1 A / dm. After 14 hours, the concentrated ferric gluconate solution was filtered and allowed to crystallize. The obtained ferric gluconate was separated from the post-crystalline liquors, washed with acetone and dried. The crystalline liquors, after replenishing the gluconic acid content, were returned to the electrolyser. The finished product contained 97% of ferrous gluconate in quantity and no appreciable amounts of calcium, sulphate and chloride ions. The content of iron ions Fe +, H "did not exceed 0.2%» Anodic proof runs with 75% current efficiency • 146 8962 146 898 PL
