Abstract
Abstract A new and useful improvement in the method for preparing synthetic crystalline aluminosilicate zeolite ZSM-35 is provided. The improved method comprises synthesizing zeolite ZSM-35 in the presence of butanediamine as template rather than the conventional template of ethylenediamine or pyrrolidine. Not only is synthesis of zeolite ZSM-35 facilitated by the present improved method, but the zeolite product is substantially more pure than that obtained by the conventional method of synthesis. Further, catalysts made with the zeolite ZSM-35 synthesized in accordance hereto are much more catalytically active than those obtained by the conventional synthesis method.
