Abstract
An aluminosilicate molecular sieve of STW framework type, designated herein as SSZ-110, and having a molar ratio of SiO2/Al2O3 of less than 100, is provided. SSZ-110 may be synthesized using an organic structure directing agent selected from one or more of 1,4-bis(2,3-dimethyl-1H-imidazolium)butane dications, 1,5-bis(2,3-dimethyl-1H-imidazolium)pentane dications, and 1,6-bis(2,3-dimethyl-1H-imidazolium)hexane dications. SSZ-110 may be used in organic compound conversion reactions and sorptive processes.
Claims10
A method of synthesizing an aluminosilicate molecular sieve of STW framework type, the method comprising:
- (a) providing a reaction mixture comprising:
- (1) a source of silicon oxide;
- (2) a source of aluminum oxide;
- (3) an organic structure directing agent (Q) comprising one or more of 1,4-bis(2,3-dimethyl-1H-imidazolium)butane dications, 1,5-bis(2,3-dimethyl-1H-imidazolium)pentane dications, and 1,6-bis(2,3-dimethyl-1H-imidazolium)hexane dications;
- (4) a source of fluoride ions;
- (5) water;
- and
- (b) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the molecular sieve.
An aluminosilicate molecular sieve of STW framework type and, in its as-synthesized form, comprising one or more of 1,4-bis(2,3-dimethyl-1H-imidazolium)butane dications, 1,5-bis(2,3-dimethyl-1H-imidazolium)pentane dications, and 1,6-bis(2,3-dimethyl-1H-imidazolium)hexane dications in its pores.
