Claims14
A process for mono- or di-iodinating an aromatic compound selected from the group consisting of biphenyl, naphthalene, anthracene, thiophene, benzothiophene, pyridine and benzopyridine which comprises reacting an iodine source with said aromatic compound in the presence of oxygen over a non-acid zeolite catalyst at a temperature from about 100.degree. C. to about 500.degree. C. wherein said non-acid zeolite catalyst contains an effective amount of an oxidation catalyst comprising at least one member selected from the group consisting of manganese, iron, copper, chromium, vanadium, molybdenum, arsenic, antimony, cobalt and boron in the oxide, salt or acid form.
A process for mono- or di-iodinating an aromatic compound selected from the group consisting of benzene, biphenyl, naphthalene, anthracene, thiophene, benzothiophene, pyridine and benzopyridine which comprises reacting an iodine source with said aromatic compound in the presence of oxygen over a non-acid catalyst selected from the group consisting of alkali or alkaline earth cations on an inert support at a temperature between about 100.degree. C. to about 500.degree. C., wherein said non-acid catalyst contains an effective amount of an oxidataion catalyst comprising at least one member selected from the group consisting of manganese, iron, copper, chromium, vandium, molybdenum, arsenic, antimony, cobalt and boron in the oxdde, salt or acid form.
