| Title: | METHODS FOR GENERATING AND RECYCLING METAL HALIDE CATALYST COMPOSITIONS FOR AROMATIC RING ALOGENATION | |||||
| Abstract: | A method for recovering and reusing a ring-halogenation catalyst comprises: (A) contacting an aromatic compound with chlorine or bromine in the presence of a catalyst composition, where the catalyst composition comprises at least one salt comprising a Group 4 - 13 metal, a lanthanide metal, or an actinide metal; and at least one organic counterion derived from an organic acid having a pKa relative to water of 0 or greater; and at least one organic sulfur compound; to form a first product mixture comprising a monochloro or a monobromo aromatic compound and a Group 4 - 13 metal halide, a lanthanide metal halide or an actinide metal halide; (B) separating the metal halide from the first product mixture; and (C) contacting at least a portion of the metal halide and an aromatic compound with chlorine or bromine, and at least one organic sulfur compound; to form a second product mixture comprising a monochloro or a monobromo aromatic compound and a Group 4 - 13 metal halide, a lanthanide metal halide or an actinide metal halide.ving a pKa relative to water of 0 or greater; and at least one organic sulfur compound. | |||||
