Abstract: There is disclosed a process for the production of unsymmetrical, substituted diarylamines by the reaction of a primary aromatic amine and a substituted phenol wherein the phenol is held in excess of the primary aromatic amine thereby minimizing by-product formation as a result of self-condensation of the primary arylamine. The desired secondary amine is produced in high yield and purity by recycling the unreacted phenol.

Abstract: A process for the production of symmetrical and unsymmetrical substituted diarylamines is disclosed. The process provides said diarylamines in high yield and purity by the reaction of a salt of an arylsulfonic acid and an alkali metal salt of a primary arylamine in the presence of an inorganic alkali metal salt.

Abstract: There is disclosed a process for the direct iodination of polyarylidene compounds to provide highly pure para-substituted diiodo derivatives. The polyarylidene compound is reacted with iodine in the presence of an oxidant, unreactive with the aromatic nucleus, in a reaction medium containing a solvent for the polyarylidene compound, a catalyst and water. The reaction medium is recovered for reuse in subsequent reactions by the removal of spent oxidant which, in the preferred embodiment, is based upon the temperature dependent differences in solubility between the diiodo derivative and the spent oxidant.
