METHOD FOR PREPARING BASIC ALUMINUM CHLOROSULFATE

摘要

A process for preparing basic aluminum chlorosulfate comprising: 1) forming a reaction mixture in an aqueous medium of aluminum chloride and aluminum sulfate in a molar ratio of aluminum chloride: aluminum sulfate ranging from about 0.75:1 to about 1:3 to 1 followed by 2) basifying the product by reacting the product of step 1) with a source of calcium sufficient and under conditions sufficient to form a polymer.
