Abstract
This invention is directed to novel benzyl quaternary ammonium compounds and their synthesis. The compounds have valuable utility as organic directing agents in the crystallization of a silicate structure which, in turn, is useful as a catalyst component, sorbent, and/or ion-exchanger. More particularly, this invention is concerned with benzyl quaternary ammonium compounds synthesized by selective alkylation of the bridgehead nitrogen of tropane or quinuclidine with a benzyl salt.
