A process for preparing the zeolite SSZ-36 which comprises: (a) preparing an aqueous solution containing sources of an alkali metal oxide, an oxide selected from the oxides of aluminum, boron, iron, gallium, or titanium, an oxide selected from silicon or germanium oxide, and at least one conformatio
A process for preparing the zeolite SSZ-36 which comprises: (a) preparing an aqueous solution containing sources of an alkali metal oxide, an oxide selected from the oxides of aluminum, boron, iron, gallium, or titanium, an oxide selected from silicon or germanium oxide, and at least one conformationally constrained water-soluble 1,3,3,8,8-pentamethyl-3-azoniabicyclo[3.2.1]octane salt having an anion which is not detrimental to the formation of the molecular sieve; (b) maintaining the aqueous solution under conditions sufficient to form crystals of molecular sieve; and (c) recovering the crystals of molecular sieve. A crystalline material composition, as synthesized and in the anhydrous state, whose general formula, in terms of oxide mole ratios, is (from about 0.5 to about 10)Q: (from about 0.1 to about 5.0)M2O:W2O3:(greater than about 15)YO2 wherein: Q is the 1,3,3,8,8-pentamethyl-3-azoniabicyclo[3.2.1]octane ring system templating agent described above; M is one or a combination of alkali metal cations and/or alkaline earth metal cations; W is one or a combination of elements selected from aluminum, boron, gallium, iron, titanium, and mixtures thereof; and Y is one or a combination of elements selected from silicon, germanium, and mixtures thereof.
