SYNTHESIS OF MSE -FRAMEWORK TYPE MOLECULAR SIEVES

摘要

An aspect of the invention relates to 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 but preferably a source of a trivalent element ,X , a source of an alkali or alkaline earth metal , M , a source of a tetraethylammonium cation , Q1, and optionally a source of a second organic cation Q2 which can include a cyclic- nitrogen containing ammonium cation.
