Abstract
A method is disclosed for synthesizing molecular sieve SSZ-98 using a structure directing agent selected from one or more of 1,1-diethylpyrrolidinium cations, 1-butyl-1-methylpiperidinium cations, 1,1-diethyl-4-methylpiperidinium cations, and 8-(pyridin-2-yl)-5,8-diazaspiro[4.5]decan-5-ium cations.
Claims8
A method of synthesizing molecular sieve SSZ-98, comprising:
- (a) preparing a reaction mixture comprising:
- (1) a source of silicon oxide;
- (2) a source of aluminum oxide;
- (3) a source of a Group 1 or 2 metal (M);
- (4) a structure directing agent (Q) selected from one or more of 1,1-diethylpyrrolidinium cations, 1-butyl-1-methylpiperidinium cations, 1,1-diethyl-4-methylpiperidinium cations, and 8-(pyridin-2-yl)-5,8-diazaspiro[4.5]decan-5-ium cations;
- (5) hydroxide ions;
- and
- (6) water;
- and
- (b) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the molecular sieve.
An SSZ-98 molecular sieve comprising within its pores a structure directing agent (Q) selected from one or more of 1,1-diethylpyrrolidinium cations, 1-butyl-1-methylpiperidinium cations, 1,1-diethyl-4-methylpiperidinium cations, and 8-(pyridin-2-yl)-5,8-diazaspiro[4.5]decan-5-ium cations.
