Abstract
The invention relates to a process for isomerizing and transiodinating iodoaromatic compounds over a non-acid catalyst.
Claims13
A process for isomerizing or transiodinating a mono-, di-, or tri-iodoaromatic compound selected from the group consisting of benzene, biphenyl, naphthalene, anthracene, thiophene, benzothiophene, pyridine and benzopyridine, comprising contacting said iodoaromatic compound with a non-acid zeolite catalyst, wherein the iodine present in said iodoaromatic compound is redistributed among the molecules of said iodoaromatic compound to form an isomerized or transiodinated product.
A process for iodinating an aromatic compound comprising:
- (a) reacting iodine and an aromatic compound selected from the group consisting of benzene, biphenyl, naphthalene, anthracene, thiophene, benzothiophene, pyridine and benzopyridine in the presence of oxygen over a 13X type zeolite catalyst containing potassium, rubidium or cesium cations to produce a mono-, di- or tri-iodoaromatic compound and
- (b) contacting said iodoaromatic compound over said zeolite catalyst, wherein the iodine present in said iodoaromatic compound is redistributed among the molecules of said iodoaromatic compound to form an isomerized or transiodinated product.
