    • A process is provided for the preparation of a novel polyaluminum calcium hydroxychloride composition of enhanced efficiency for water treatment, paper sizing, and antiperspirant applications. The polyaluminum calcium hydroxychloride compositions are prepared via the acidification of higher basicity reaction products to form mid-to-high basicity final products. Two methods are provided for the preparation of higher basicity products, contemplated in the first, and an aqueous acid solution, such as hydrochloric acid, aluminum chloride, or a mixture thereof, is mixed with a strong alkaline calcium salt such as calcium oxide or calcium carbonate and aluminum powder at temperatures greater than 60°C. In a second method, bauxite, aluminum hydrate, or aluminum metal, and calcium aluminate are mixed with hydrochloric acid and are reacted at high temperatures and/or elevated pressures for a certain period of time whereby, when the reaction is complete, the mixtures are filtered to obtain clear solutions. The final PAC-Ca solutions may be dried to powder to have a wide range of basicities from about 40% to about 80%. At lower basicities, the polyaluminum calcium hydroxychloride sales are used preferably as antiperspirants, while at higher basicities, the solutions are used preferably as water treatment chemicals.
