ABSTRACT:
Aluminum salts of a carboxylic acid selected from the group consisting of ascorbic acid, acetic acid, and citric acid are formed by contacting the carboxylic acid with activated aluminum. The activated aluminum is formed by combining highly pure aluminum with another metal which has an affinity for hydrogen in the presence of a proton source. Typically, the other metal can be gallium and the proton source can be hydrochloric acid. Included in the aluminum salts which can be formed are polymeric aluminum salts.
