Methods to produce zeolites with the GME topology and compositions derived therefrom

A crystalline microporous aluminosilicate composition of GME topology comprising:

• (a) an oxide of silicon, and optionally an oxide of germanium;
• (b) an oxide of aluminum, and optionally one or more oxides of boron, gallium, hafnium, iron, tin, titanium, indium, vanadium, or zirconium, wherein the molar ratio of the metals of (a) to the metals of (b) is from 4 to 4.2;
• and which crystalline microporous aluminosilcate composition of GME topology exhibits a powder XRD pattern having peaks having 2-theta values at 7.5+0.10, 11.6+0.10, 14.9+0.10, 17.9+0.2°, 19.9+0.1°, 21.75+0.15°, 28.1+0.20°, and 30.1+0.10, wherein the crystalline microporous aluminosilicate composition has pores that contain at least one isomer of the quaternary piperidinium cation of Formula (I):
• wherein
• RA and RB are independently a C1-3 alkyl, or together with the N to which they are bound form a 5 or 6 membered saturated or unsaturated ring;
• and R2, R3, R4, R5, and R6 are independently H or C1-3 alkyl, provided at least two of R2, R3, R4, R5, and R6 are independently C1-3 alkyl;
• and the quaternary piperidinium cation has an associated bromide, chloride, fluoride, iodide nitrate, or hydroxide anion.
