Claim:
A process for alkylating aromatic hydrocarbons comprising contacting a hydrocarbon feedstock comprising at least one alkylatable aromatic and a stream comprising at least one olefin having from 2 to about 6 carbon atoms with a catalyst at alkylation conditions and producing an alkylated aromatic product wherein the catalyst comprises a UZM-37 microporous crystalline zeolite having a three-dimensional framework of at least AlO 2 and SiO 2 tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of: M m + R r Al 1-x E x Si y O z where M represents sodium or a combination of potassium and sodium exchangeable cations, “m” is the mole ratio of M to (Al+E) and varies from about 0.05 to about 2, R is a singly charged propyltrimethylammonium cation, “r” is the mole ratio of R to (Al+E) and has a value of about 0.25 to about 3.0, E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, “x” is the mole fraction of E and has a value from 0 to about 1.0, “y” is the mole ratio of Si to (Al+E) and varies from greater than 8 to about 40 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: z =( m+r+ 3+4 ·y )/2 and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A: TABLE A 2θ d (Å) I/Io % 3.22-3.48 25.35-27.44 m 6.62-6.92 12.76-13.34 m 7.12-7.39 11.93-12.4 s-vs 7.92-8.32 10.61-11.15 m 8.64-8.81 10.01-10.22 m 9.71-9.85 8.97-9.09 m 12.75-12.78 6.92-6.93 w 13.39-13.72 6.44-6.6 w 14.34-14.5 6.1-6.17 w 20.13-20.2 4.39-4.4 m 21.56-21.64 4.1-4.11 m 22.14-22.28 3.98-4.01 m 23.09-23.35 3.8-3.84 m 23.95-23.97 3.7-3.71 w-m 24.92-25.19 3.53-3.57 m 25.92-26.21 3.39-3.43 vs 26.7-26.77 3.32-26.7 m 28.99-29.32 3.04-3.07 w-m 31.51-31.64 2.82-2.83 w 33.3-33.69 2.65-2.68 w 37.68-37.94 2.36-2.38 w 46.05-46.29 1.95-1.96 w 48.78-48.94 1.85-1.86 w is thermally stable up to a temperature of at least 600° C. and has a BET surface area of less than about 420 m 2 /g.
