Titanium-containing molecular sieves

Crystalline molecular sieves comprising pores having nominal diameters of greater than about 3 Angstroms and whose chemical composition in the as-synthesized and anhydrous form is represented by the unit empirical formula:

• mR:(Ti.sub.x Al.sub.y P.sub.z)O.sub.2
• wherein "R" represents at least one organic templating agent present in the intracrystalline pore system;
• "m" represents the moles of "R" present per mole of (Ti.sub.x Al.sub.y P.sub.z)O.sub.2 has a value of between zero and about 5.0;
• and "x", "y" and "z" represent the mole fractions of titanium, aluminum and phosphorus, respectively, present as tetrahedral oxides, said mole fractions being such that they are within the pentagonal compositional area defined by points A, B, C, D and E of the ternary diagram which is FIG. 1 of the drawings, said points A, B, C, D and E representing the following values for "x", "y" and "z":
• ______________________________________ Mole Fraction Point x y z ______________________________________ A 0.001 0.45 0.549 B 0.88 0.01 0.11 C 0.98 0.01 0.01 D 0.29 0.70 0.01 E 0.001 0.70 0.299. ______________________________________
