Synthesis of MSE-framework type molecular sieves

摘要

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, optionally a source of a trivalent element, X, a source of an alkali or alkaline earth metal, M, and a source of organic dications, Q, such as 3-hydroxy-1-(4-(1-methylpiperidin-1-ium-1-yl)butyl)quinuclidin-1-ium, 3-hydroxy-1-(5-(1-methylpiperidin-1-ium-1-yl)pentyl)quinuclidin-1-ium, 1,1′-(butane-1,4-diyl)bis(1-methylpiperidin-1-ium), 1,1′-(pentane-1,5-diyl)bis(1-methylpiperidin-1-ium), 1,1′-(hexane-1,6-diyl)bis(1-methylpiperidin-1-ium), and 1,1′-((3as,6as)-octahydropentalene-2,5-diyl)bis(1-methylpiperidin-1-ium).

1. 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:
R1—R3—R2 where R1 and R2 are the same or different, and where R1 or R2 or both R1 and R2 are an N-alkylpiperidinium group of the formulaor where R1 or R2 or both R1 and R2 are a quinuclidinium group of the formulawhere R3 is an polymethylene group of the formula (CH2)n, where n is from 4 to 6, or where R3 is a cylcoalkylene group having from 5 to 8 carbon atoms, andwhere R4 is an alkyl group having 1 to 4 carbon atoms.
