    Publication number: 20100210858
    Abstract: A process for preparing a catalyst by selecting an active catalyst and contacting the active catalyst with one or more fluids containing an organic solvent or mixture of organic solvents. In one embodiment, each organic solvent has a dielectric constant within a range of about 5 to about 55 when measured at a temperature of 20° C. to 25° C. The catalyst thus prepared may be used in a process for preparing maleic anhydride.
