Abstract
This disclosure relates to a ferrosilicate molecular sieve of MTW framework topology, its synthesis and use. Ferrosilicate MTW may be directly prepared using 1,3-diisobutylimidazolium cations as a structure directing agent. Ferrosilicate MTW may be used in organic compounds conversion and absorptive processes.
Claims14
A ferrosilicate molecular sieve of MTW framework topology having a d50 crystal size of 0.5 microns or less.
A method of making a ferrosilicate molecular sieve of MTW framework topology, the method comprising:
- (1) forming a reaction mixture comprising:
- (a) a source of iron;
- (b) a source of silicon;
- (c) a source of an alkali metal [M];
- (d) a structure directing agent [Q] comprising 1,3-diisobutylimidazolium cations;
- (e) a source of hydroxide ions;
- and
- (f) water;
- and
- (2) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the ferrosilicate molecular sieve.
