<p>Novel crystalline molecular sieves of the formula aX2O:bM2O3:cSiO2 where X is a monovalent cation selected from alkali metals, ammonium and hydrogen or a mixture thereof, M is a trivalent metal selected from A1, B, Fe, Ga or Cr or a mixture thereof, a = 0.0 to 1.0, b = 0.0 to 1.0, and c = 20 or above are made by heating together sources of the cation X, the trivalent metal M and silicon in the presence of a nitrogen-containing organic compound until the product crystallizes. The structure of molecular sieves prepared by the process of the present invention are characterized by the x-ray diffraction pattern given in the following Table: <IMAGE></p> |
