Abstract
A method of synthesizing a crystalline molecular sieve having an MSE framework type comprises crystallizing a reaction mixture comprising a source of water, a source of an oxide of a tetravalent element, Y, selected from at least one of silicon, tin, titanium, vanadium and germanium, a source of an alkali or alkaline earth metal, M, and a source of organic cations, Q, having the following general structure: in which R1 is hydrogen or an alkyl group, and R2 and R3 are alkyl groups.

A method of synthesizing a crystalline molecular sieve having an MSE framework type, the method comprising crystallizing a reaction mixture comprising a source of water, a source of an oxide of a tetravalent element, Y, selected from at least one of silicon, tin, titanium, vanadium and germanium, optionally a source of a trivalent element, X, a source of an alkali or alkaline earth metal, M, and a source of organic cations, Q, having the following general structure:
- in which R1 is hydrogen or an alkyl group, and R2 and R3 are alkyl groups.
A crystalline molecular sieve having an MSE framework type and containing within its pore structure 1,1-dialkyl-4-cyclohexylpiperazin-1-ium cations and/or 1,1-dialkyl-4-alkylcyclohexylpiperazin-1-ium cations.
