Abstract
A method is provided for synthesizing a molecular sieve having the framework structure of SSZ-109 using N1,N6-diisopropyl-N1,N1,N6,N6-tetramethylhexane-1,6-diaminium cations as a structure directing agent.
Claims10
A method of synthesizing a molecular sieve having the structure of SSZ-109, the method comprising:
- (a) providing a reaction mixture comprising:
- (1) a source of silicon oxide;
- (2) a source of an oxide of a trivalent element (X);
- (3) optionally, a source of a Group 1 or Group 2 metal (M);
- (4) a structure directing agent (Q) comprising N1,N6-diisopropyl-N1,N1,N6,N6-tetramethylhexane-1,6-diaminium cations;
- (5) a source of hydroxide ions;
- and
- (6) water;
- and
- (b) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the molecular sieve.
