A method of synthesizing a zeolite comprising the steps of: a. preparing an admixture containing (i) at least one source of alumina, (ii) at least one source of silica, and (iii) at least one structure directing agent (SDA) in hydroxide form, wherein the admixture is essentially free of alkali metals, wherein the at least one structure directing agent (SDA) in hydroxide form is N,N-diethyl-2,6-dimethylpiperidinium; and b. heating the admixture under autogenous pressure at a temperature and with stirring or mixing for a sufficient time to crystalize hydrogen-form zeolite crystals having an AEI framework. |
