ABSTRACT:
A stable monolithic gel produced by reacting an alumina hydrate sol with an organic reactant selected from the group consisting of polycarboxylic acids having esterified acid groups, anhydrides of polycarboxylic acids, and water-soluble cationic or neutral polyacrylamides. A particularly preferred gel is made by reacting an alumina monohydrate sol with dimethyl oxalate. The preferred monolithic gel remains transparent or slightly cloudy upon storage with little syneresis.
