Ammonium, alkylammonium, alkali metal, alkaline earth metal and groups IB, IIB, VIB, VIIB, VIII metal salts of aminoaryl sulfonic acid salts, and the salts of sulfanilic acid in particular, can be reacted with alkenyl or alkylsuccinic anhydride, acid or ester, in which the alkenyl or alkyl group may contain from 8 to about 500 carbon atoms, to yield the products of this invention. These products are understood to be novel. Suitable modifications of the aforementioned are the succinimides of di(aminoaryl sulfonic acid) salts, aniline disulfonic acid salts and corresponding aminonaphthalene sulfonate salts which are also useful in the compositions of this invention.

Abstract: As synthesized by previous methods, ZSM-5 or ZSM-11 zeolites are crystallized in the presence of substantial amounts of a nitrogen-containing compound. When synthesized in this way, they contain an organic ammonium cation as well as a metal cation such as sodium. To obtain a more active form, the sodium ion must be exchanged out. Such exchange, especially with ZSM-5 and ZSM-11, is difficult unless there is calcination of the zeolite to remove the obstructing organo compounds. By making these zeolites in the presence of (1) seeds of the desired zeolite, (2) mixtures of them with ammonium hydroxide and/or alcohol, (3) the alcohol per se or (4) mixtures of the alcohol with ammonium hydroxide, a product substantially deficient in organic ammonium cation is obtained. These products can be exchanged directly without any calcination.
