A METHOD OF PREPARING A CRYSTALLINE ALUMINOSILICATE ZEOLITE ABSTRACT OF THE DISCLOSURE A method is disclosed for synthesizing a crystalline aluminosilicate zeolite containing an organic nitrogen cation in the presence of a primary monoalkylamine having 2 to 10 carbon atoms in the alkyl portion. The method produces a zeolite having a very low percentage, i.e. no more than about 0.2 weight percent, of alkali metal, e.g. sodium, in the as-synthesized form. The product can be used directly as a catalyst without intermediate precalcination and cation exchange. This is not possible with zeolites such as those of the ZSM-5 type synthesized by the methods of the art.
