Abstract
Described is a process for producing a diarylamine, which comprises subjecting an arylamine to condensation reaction in the co-presence of anhydrous aluminum chloride and anhydrous calcium chloride. The process permits the production of a diarylamine in a high yield at a normal pressure while terminating the reaction in a short time; and also permits the production, at a low cost, of a diarylamine having a high purity to be usable sufficiently as an intermediate for the production of a raw material for an electronic material.
