Abstract

Official abstract text for this publication.

Crystalline molecular sieves and their synthesis using quaternary N-methyl-diisoalkylammonium cations as organic structure directing agents are disclosed. The structure directing agent has the following structure (1): in which R 1 is selected from hydrogen, a methyl group, an ethyl group, a propyl group, and a hydroxymethyl group; and R 2 , R 3 , R 4 and R 5 are independently selected from a methyl group, an ethyl group, and a propyl group.

First claim

Opening claim text (preview).

The invention claimed is: 1. A crystalline molecular sieve, wherein the molecular sieve has a framework type of SSZ-45 and a three-dimensional framework comprising oxides of silicon and aluminum, comprising within its pore structure N,N-dimethyl-di-sec-butylammonium cations.
