Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A crystalline aluminosilicate zeolite having a composition, as synthesized and in anhydrous form, in terms of mole ratios of oxides as follows: (0.5-1.3)R 2 O: (0-0.15 Na 2 O) : (0.10-0.50) K 2 O : Al 2 O 3 : X SiO 2 where R is the organic nitrogen-containing cation derived from choline and X is 8 to 50, said zeolite being characterized by: (1) an X-ray powder diffraction pattern set forth in Table 1 of the specification; and (2) the capability, after calcination at 1000° F for at least a time to remove the organic cation, of sorbing at least 9.5 weight percent of n-hexane at ambient temperature and a n-hexane pressure of 20 mm.
