ABSTRACT:
A basic aluminum hydroxycarbonate hydrate, usable as an antacid, is prepared by simultaneously adding aqueous solutions of aluminum sulfate and alkali hydrogen carbonate or alkali carbonate to water while maintaining a neutral or weakly alkaline pH and adjusting the pH-value of the reaction mixture, after completed precipitation, to about 6.0 by adding an aluminum salt of a strong acid.
