Abstract
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 R1 is selected from hydrogen, a methyl group, an ethyl group, a propyl group, and a hydroxymethyl group; and R2, R3, R4 and R5 are independently selected from a methyl group, an ethyl group, and a propyl group.
Claims5
A crystalline molecular sieve, wherein the molecular sieve has a framework of SSZ-47 and the three-dimensional framework comprising oxides of silicon and aluminum, comprising within its pore structure N,N-dimethyl-di-sec-butylammonium cation.
