Procedure
266 g of water and then 77.8 g of calcium hydroxide were introduced into a reactor with stirring. After homogenization of the suspension, a solution of 147.1 g of citric acid monohydrate in 266 g of water was introduced. A calcium citrate precipitate was thus obtained, which precipitate was subsequently filtered off and dried at 65° C. The final product thus obtained has a solubility in water of 1.0 g.l−1 and its calcium, assay is 24%.
