Abstract:
1. A process for alkylating aromatic compounds comprising reacting under alkylation conditions and under at least partial liquid phase conditions an olefin with an alkylatable aromatic compound in the presence of a catalyst to provide an alkylated compound, the catalyst comprising a zeolite having a composition in the as synthesized form on an anhydrous basis in terms of mole ratios of the elements given by empirical formula: where M is at least one exchangeable cation selected from the group consisting of alkali and alkaline earth metals, “m” is the mole ratio of M to (Al+E) and varies from more than 0 to about 1.2, C is at least one organic nitrogen containing cation, having C/N>4 and characterized in that it is a charge density mismatch template, selected from the group consisting of quaternary ammonium ions, diquaternary ammonium ions, and quaternized alkanolammonium ions, “g” is the mole ratio of C to (Al+E) and varies from more than 0 to about 5, R is at least one crystallization-inducing organic cation which differs from C and is selected from the group consisting of quaternary ammonium ions, diquaternary ammonium ions, protonated amines, protonated diamines, protonated alkanolamines and quaternized alkanolammonium ions, “r” is the mole ratio of R to (Al+E) and has a value from more than 0 to about 3, where g+r>0.2, “n” is the weighted average valence of M and has a value of about 1 to about 2, “h” is the weighted average valence of C and has a value of about 1 to about 2, “p” is the weighted average valence of R and has a value of about 1 to about 2, E is an element selected from the group consisting of gallium, iron, boron, indium, chromium, titanium, zirconium, and mixtures thereof, “x” is the mole fraction of E and has a value from 0 to about 0.5, “y” is the mole ratio of Si to (Al+E) and varies from about 5 to about 12; “z” is the mole ratio of O to (Al+E) and has a value determined by the equation the zeolite having (i) at least two x-ray diffraction peaks, one at a d-spacing of 3.9±0.12 Å and one at a d-spacing 8.6±0.20 Å; (ii) a tetragonal unit cell; and (iii) a micropore volume ranging from about 0.11 cc/g to about 0.17 cc/g.
