  • Patent number: 10752603
    Abstract: A process for the purification of an oxydiphthalic anhydride includes contacting a mixture of an oxydiphthalic anhydride and at least one of the corresponding oxydiphthalic diacid, a corresponding oxydiphthalic tetraacid, a halophthalic anhydride, and a catalyst with a solvent to provide a slurry. The solvent is capable of solubilizing the corresponding oxydiphthalic diacid, the corresponding oxydiphthalic tetraacid, the halophthalic anhydride, and the catalyst at a temperature of 15 to 50° C., and the oxydiphthalic anhydride is substantially insoluble in the solvent at this temperature. The oxydiphthalic anhydride can be isolated from the slurry. A purified oxydiphthalic anhydride and a polyetherimide prepared therefrom are also disclosed.
