Patent ID: 7473807

Claim:
A method for performing an acylation reaction on an aromatic substrate ArH n to form a product ArH n-1 COR, the method comprising the steps of: a. providing the aromatic substrate, b. intimately mixing the substrate and an acylating agent, wherein the acylating agent is selected from the group consisting of a carboxylic acid derivative, a carboxylic acid, an acid anhydride, an ester, and an acyl halide, and c. exposing an intimate mixture thus formed to a catalyst comprising a crystalline molecular sieve having a mole ratio greater than about 15 of (1) an oxide of a first tetravalent element to (2) an oxide of a trivalent element, pentavalent element, second tetravalent element which is different from said first tetravalent element or mixture thereof and having, after calcination, the X-ray diffraction lines of Table II, as follows: TABLE II Calcined SSZ-74 Relative Integrated 2 Theta (a) d-spacing (Angstroms) Intensity (%) 7.98 11.07 M 8.70 10.16 VS 8.89 9.93 S 9.08 9.74 S 14.02 6.31 W 14.93 5.93 M 16.03 5.52 M 23.26 3.82 VS 23.95 3.71 W 24.08 3.69 M (a) ±0.1.
