Claim 0:
1. A microporous aluminotitanosilicate crystalline zeolite having a three-dimensional framework of A1O2, SiO2 and TiO2 tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of:

TipMmn+AlxSiOy, wherein:
p is the mole ratio of Ti to Si and has a value from 0.005 to about 0.1,
M represents a potassium ion and/or sodium ion, or their exchangeable cations,
m is the mole ratio of M to Si and varies from about 0.001 to about 0.05,
n is the valence of M,
x is the mole ratio of Al to Si and varies from 0.0025 to about 0.1; and
y has a value determined by the equation:

y=(4·p+m·n+3·x+4)/2

and is characterized in that it has the x-ray diffraction pattern having at least the intensities set forth in Table A:, TABLE A
