Acylation using molecular sieve ssz-70

A method for performing an acylation reaction on an aromatic substrate ArHn to form a product ArHn-1COR, the method comprising the steps of:

• providing the aromatic substrate,
• 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
• exposing an intimate mixture thus formed to a catalyst comprising a molecular sieve having a mole ratio greater than about 15 of (1) silicon oxide to (2) an oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide, titanium oxide, vanadium oxide and mixtures thereof and having, after calcination, the X-ray diffraction lines of Table II.
