1 by calcium lactate or sodium lactate solution with ferrous sulfate or ferrous chloride derived reaction. buffered lactic acid was added refined sugar and iron, direct response obtained after crystallization. In order to prevent oxidation, the reaction should be concentrated, crystallized and dried, sealed.
2, the calcium lactate or sodium lactate with ferrous sulfate (ferrous sulfate and the solvent water mass ratio of 2:1) in 45 ~ 50 ℃ and 2.5 ~ 3.0 Ph value 40min reaction conditions can be obtained products.
3, by the addition of ferrous sulfate or calcium lactate solution plus ferric chloride solution obtained, but also by Calcium lactate solution was added sucrose and refined iron reaction, and then crystallization derived ferrous lactate.
