FERROUS GLUCONATE DIHYDRATE Use and Manufacturing
Directly process calcium gluconate and ferrous sulfate in the presence of a small amount of iron powder, react at 90°C for 10 hours to obtain the product with a yield of 97.8%. The process of this method is simple, but the residual calcium sulfate is too high to be removed. (C6H11O6O)2Ca+FeSO4→(C6H11O6O)2Fe+CaSO4↓ acid method add 1.2mol/L of calcium gluconate to the same amount of sulfuric acid solution under stirring, and react at 90℃ for 1h; filter to remove the precipitated calcium sulfate After that, the column was passed through the column at a flow rate equivalent to the volume of the resin per minute to obtain about 35% gluconic acid solution with a yield of 97%. Add ferrous sulfate powder to sodium carbonate solution, stir to dissolve and react to form ferrous carbonate precipitate: FeSO4+Na2CO3→Na2SO4+FeCO3↓After the reaction is completed, filtered and washed to obtain ferrous carbonate (do not drain, leave a water layer on the surface to isolate Air), the yield is 98%. Then ferrous carbonate was added to the gluconic acid solution and stirred for 30 minutes, and the CO2 produced by the reaction was used as an inert gas to protect it. The product ferrous gluconate solution is put into a crystallization tank, and seed crystals are added, and the crystallization is completed in about 3 to 5 hours. Finally, it is filtered, washed with ethanol, and dried under vacuum at 50°C to obtain the finished product with a yield of 98%. C6HllO6OH+FeCO3→(C6H11O6O)2Fe+H2O+CO2↑
As a feed iron fortifier, its absorption effect is better than inorganic iron.
