Abstract
The present invention is directed to a method for making a new crystalline molecular sieve designated SSZ-83 using a 1,4-bis(N-butylpiperidinium)butane dication or a 1,4-bis(N-butylpyrrolidinium)butane dication as a structure directing agent.
Claims14
A method for preparing a molecular sieve comprising contacting under crystallization conditions:
- (1) at least one source of an oxide of a first tetravalent element;
- (2) optionally, one or more sources of an oxide selected from the group consisting of oxides of a trivalent element, a pentavalent element, a second tetravalent element which is different from the first tetravalent element, and mixtures thereof;
- (3) fluoride ions;
- and (4) a structure directing agent selected from the group consisting of 1,4-bis(N-butylpiperidinium)butane dications and 1,4-bis(N-butylpyrrolidinium)butane dications.
