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.
描述了一种制备二芳基胺的过程,包括在无水氯化铝和无水氯化钙共存下,将芳基胺进行缩合反应。该过程可以在常压下,在短时间内停止反应,高产率地制备二芳基胺;并且可以以低成本制备高纯度的二芳基胺,足以用作电子材料原材料的中间体。
