Abstract
A method is provided for the synthesis of a zeolite of the offretite structure using cyclopropyltrimethylammonium cations as a structure directing agent.
Claims8
A method of preparing a zeolite of OFF framework type, the method 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 Group 2 metal (M);
- (4) a structure directing agent (Q) comprising cyclopropyltrimethylammonium 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 zeolite.
