Abstract: This disclosure relates to the use of 1-methyl-6,7-dihydro-5H-cyclopenta[b]pyridine-1-ium cation as structure directing agent (SDA) for the preparation of zeolites. This disclosure also relates to compositions of matter, designated as EMM-64 and EMM-65, obtainably by using this SDA, as well as a method of making the same and uses thereof. This disclosure further relates to a method of making an aluminosilicate molecular sieve of RTH framework type using said SDA, aluminosilicate molecular sieves of RTH framework type obtainable by said method, and uses thereof.

Abstract: Various zeolites may be produced under hydrothermal synthesis conditions in the presence of a silicon atom source and a bis-pyridinium compound having a structure represented by formula (I). Q is an optionally substituted C1-C10 hydrocarbyl group and two Q may join to form a carbocyclic ring; n is an integer ranging from 0 to 5; m is an integer ranging from 0 to 5; n+m is greater than or equal to 1; and A is a spacer group containing 2 to about 10 atoms.

Abstract: A method can include heating an aqueous reaction mixture comprising a silicon source and a boron source and/or an aluminum source in the presence of a quaternary structure directing agent to a temperature of at least 75° C. to produce a zeolite. A composition can include a borosilicate zeolite, an aluminosilicate zeolite, or an aluminoborosilicate zeolite having a framework symmetry of C2/m and a unit cell with measurements of a of 3.5 Å to 4.5 Å, b of 20.1 Å to 21.1 Å, c of 15.5 to 16.5 Å, and β of 97° to 98°.
