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-diazabicyclo2.2.2!octane cations and N-benzyl-1-azabicyclo2.2.2!octane cations.
Claims7
A method of preparing a crystalline material having a mole ratio of a first oxide selected from silicon oxide, germanium oxide and mixtures thereof to a second oxide selected from aluminum oxide, gallium oxide, iron oxide, titanium oxide, boron oxide and mixtures thereof greater than about 10 and wherein at least 50% of the second oxide is boron oxide, said method comprising contacting under crystallization conditions sources of said oxides and a templating agent comprising cations selected from the group consisting of N-benzyl-1-azabicyclo2.2.2!octane cations having the structure ##STR3## where R is --OH or --NH.sub.2, and N-benzyl-1,4-diazabicyclo2.2.2!octane cations.
