Abstract
A crystalline zeolite, SSZ-13, is prepared from organic nitrogen-containing cations derived from 1-adamantamine, 3-quinuclidinol, and 2-exo-aminonorbornane,
Claims10
A zeolite having a mole ratio of an oxide as synthesized selected from the group consisting of silicon oxide, germanium oxide and mixtures thereof to an oxide selected from the group consisting of aluminum oxide, gallium oxide, and mixtures thereof greater than 5:1, and having the X-ray diffraction pattern of Table 1.
A zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios of oxides as follows:
- (0.5 to 1.0)R.sub.2 O:(0 to 0.50)M.sub.2 O--W.sub.2 O.sub.3 :
- (greater than 5) YO.sub.2 wherein M is an alkali metal cation, W is selected from the group consisting of aluminum, gallium and mixtures thereof, Y is selected from the group consisting of silicon, germanium and mixtures thereof, R is a quaternary lower alkylammonium cation compound selected from the group consisting of N-alkyl-3-quinuclidinol, N,N,N-tri-alkyl-1-adamantammonium, and N,N,N-trialkyl-exoaminonorbornane, or mixtures thereof, and having the X-ray diffraction pattern of Table 1.
