Abstract
The present invention relates to new crystalline zeolite SSZ-42 prepared by processes for preparing crystalline molecular sieves, particularly large pore zeolites, using an organic templating agent selected from the group consisting of N-benzyl-1,4-diazabicyclo[2.2.2]octane cations and N-benzyl-1-azabicyclo[2.2.2]octane cations.
Claims7
A zeolite having a composition, as-synthesized and in the anhydrous state, in terms of mole ratios as follows:
- ##STR3## wherein Q is comprised of cations selected from the group consisting of N-benzyl-1-azabicyclo[2.2,2]octane cations having the structure ##STR4## where R is --OH or --NH.sub.2, and N-benzyl-1,4-diazabicyclo[2.2.2]octane cations, M is an alkali metal cation or alkaline earth metal cation, x is 1 or 2, W is an atom selected from the group consisting of boron, aluminum, gallium, iron, titanium, and mixtures thereof wherein at least 50% of W is boron, and Y is selected from the group consisting of silicon, germanium, and mixtures thereof, said zeolite having the X-ray diffraction lines of Table I.
