TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The SiC is in the beta-form (beta-SiC) and has BET specific surface area 10-600 (preferably 10-100) m2/g. The carrier is especially foamed SiC. The zeolite is an aluminosilicate, metallosilicate, silico-aluminophosphate, metallo-aluminophosphate, aluminophosphate or metallophosphate, preferably having the AEL, BEA, CHA, CLO, ERJ, EUO, FAU, FER, HEU, LTA, LTL, MAZ, MEI, MEL, MFI, MOR, MTT, MTW, MWW, OFF, PHI, SOD or TON structure. In particular the zeolite is zeolite ZSM-5, zeolite-beta or silicalite. The carrier is calcined before the deposition of the zeolite, preferably under conditions such that a silica layer having a thickness of 1-10 (preferably 1.5-5) nm (measured by XPS spectroscopy) is formed. EXAMPLE - A composite containing zeolite-beta (structural type BEA) was prepared by hydrothermal synthesis starting from a gel containing the necessary reactants. The gel comprised water, Aerosil 200 (RTM: silica), aluminum and tetraethylammonium hydroxide (TEAOH), and had a molar composition in oxide form of 100 SiO2: 1 Al2O3 : 14 TEA2O : 740 H2O. 3.87 g of Aerosil 200 (RTM) were dissolved in a solution of 10.213 g TEAOH in 7.70 g water at 50 degrees C; and 5.65 g of aluminum was separately dissolved in 5.65 g TEAOH at 50 degrees C. The solutions were mixed under stirring at 50 degrees C, and the obtained gel was matured under the same conditions for 50 minutes. 10 g of beta-silicon carbide (as 250-425 micron particles; previously calcined at 900 degrees C for 2 hours) were added. After maturing for 10 minutes, the mixture was heated at 140 degrees C in an autoclave for 24 hours. The obtained zeolite-beta/SiC composite was washed with water, recovered by filtration, sonicated in ethanol for 10 minutes, calcined in air for 12 hours at 550 degrees C, converted into the ammonium form by cation exchange with 1M aqueous ammonium chloride solution and further calcined in air for 12 hours at 550 degrees C to give the acid form H-zeolite-beta/SiC composite (Ia), containing 10 wt. % zeolite.    When (Ia) was used to catalyze the acetylation of anisole with acetic anhydride, methoxyacetophenone was obtained with 100% selectivity to the para-isomer.
