ABSTRACT An improved process for synthesizing an improved crystalline aluminosilicate zeolite is provided. The improved process comprises forming a reaction mixture containing one or more sources of alkali metal oxide, organic nitrogen-containing cations, acid ions, an oxide of silicon, an oxide of aluminum and water wherein the mole ratio of hydroxide ions/silica in said reaction mixture is at most about 10-2 and the acid ions are present in said reaction mixture in amount less than the equivalents of organic nitrogen present therein, and wherein the pH of said reaction mixture is at least about 7, and maintaining the reaction mixture at a temperature and pressure for a time necessary to crystallize therefrom said crystalline aluminosilicate zeolite. Improvement in the present synthesis process resides, for example, in reduced crystallization time and reduced organic nitrogen- containing cation source requirement. Improvement in zeolite produce from the present improved process resides, for example, in enhanced purity.
