Abstract
A method is provided for synthesizing zeolite SSZ-31 using 2-ethyl-N,N,N-trimethylbutan-1-aminium cations as a structure directing agent.
Claims7
A method of synthesizing a zeolite having the structure of SSZ-31, the method comprising:
- (a) preparing a reaction mixture comprising:
- (1) a source of silicon oxide;
- (2) optionally, a source of aluminum oxide;
- (3) a structure directing agent (Q) comprising 2-ethyl-N,N,N-trimethylbutan-1-aminium cations;
- (4) hydroxide ions;
- and
- (5) water;
- and
- (b) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the zeolite.
