Abstract:
1. 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:
