Abstract
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 9 carbon atoms in the alkyl portion. The method produces a zeolite having a very low percentage, i.e. less than about 0.14 weight percent, generally less than about 0.1 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.
