Abstract
A method is provided for synthesizing *MRE molecular sieves using an organic structure directing agent which comprises a 1-ethylpyridinium cation.
Claims4
A method of synthesizing an aluminosilicate molecular sieve of *MRE framework, the method comprising:
- (1) preparing a reaction mixture comprising:
- (a) a silicon atom source;
- (b) an aluminum atom source;
- (c) an organic structure directing agent [Q] which comprises a 1-ethylpyridinium cation;
- (d) a source of an alkali metal [M];
- (e) a source of hydroxide ions;
- and
- (f) water;
- and
- (2) subjecting the reaction mixture to crystallization conditions-sufficient to form crystals of the aluminosilicate molecular sieve of *MRE framework;
- wherein the source of both the silicon atom and the aluminum atom is a Y-zeolite.
