Abstract
A process for making a modified boehmite alumina comprising reacting at elevated temperatures a boehmite alumina with a compound having the formula: EQU X(SO.sub.3 M).sub.n wherein X is an organic moiety, M in a monovalent cation, and n is an integer reflecting the number of SO.sub.3 M groups bonded to said organic moiety to produce a reaction mixture containing modified boehmite alumina and recovering solid, modified boehmite alumina from the reaction mixture.
