PROCESS FOR PRODUCING STABLE MAGNESIUM CITRATE TRIHYDRATE AND COMPOSITION CONTAINING THE SAME

摘要

1)controlling the mole ratio of citric acid monohydrate and magnesium carbonate to 1:1.25; 2)adding purified water as much as 2.5 times the above mixture; 3)adding 0.1-0.5% talc and mixing for 10 min.; 4)filtering and controlling the pH of the filtered solution by sodium or potassium hydroxide; 5)making powder phase compd.. using a high temp. spray dryer. The temp of inlet of dryer is 200-250 deg.C; and that of outlet is 100-150deg.C.
