Claims12
A process for producing a reaction product of a calcium compound selected from the group consisting of calcium hydroxide, calcium oxide and calcium carbonate with citric acid wherein the reaction product has a mole ratio of calcium to citric acid from 2.50:2 to 2.95:2 and a pH value in a 1% water slurry of said reaction product about 4 to below 7 at 25.degree. C. which comprises:
- (a) reacting a mixture of an aqueous slurry of said calcium compound and an aqueous solution of said citric acid at mole ratios of said calcium compound to citric acid of less than 3:2 at a rate to avoid temperatures of heat of reaction exceeding 60.degree. C. and maintaining a pH of said mixtures during the reaction in the range from about 4 to about 7 to obtain a solids level of said reaction mixture from about 20 to about 26% by weight;
- and
- (b) cooling said reaction mixture of (a) below about 100.degree. F.
