    摘要: This invention provides a novel process for the preparation of substituted derivatives of diphenyl amine. The special feature of this novel process is that low cost and recoverable phenolic salts are used as catalysts for molecular rearrangement and aminolysis to obtain substituted derivatives of diphenyl amine in high yield.
