ABSTRACT:
A zeolite composition CIT-1 is provided, the composition having a mole ratio greater than about 20:1 of a first oxide selected from silicon oxide, germanium oxide, or mixtures thereof to a second oxide comprising boron oxide; which zeolite composition has a specific X-ray powder diffraction pattern in accordance with Table 1 of the disclosure. In one embodiment, the second oxide may comprise mixtures of boron oxide with one or more of aluminum oxide, gallium oxide, iron oxide, titanium oxide and vanadium oxide. Also disclosed is a method for making CIT-1 zeolites comprising the preparation of an aqueous mixture containing sources of a N,N,N-trimethyl cis-myrtanyl ammonium ion, boron oxide or mixtures of boron oxide with one or more of aluminum oxide, gallium oxide, iron oxide, titanium oxide and vanadium oxide, and an oxide selected from silicon oxide, germanium oxide, and mixtures thereof. The mixture is maintained under sufficient crystallization conditions, preferably at a temperature of at least 100.degree. C., in an autoclave and under autogenous pressure until the crystals of the zeolite are formed.
