MANUFACTURING METHOD OF 4,4-DINITRODIPHENYLAMINES AND A MANUFACTURING METHOD OF 4,4-BIS(ALKYLAMINO)DIPHENYLAMINES FROM EXCESS AMOUNT OF NITROBENZENE AND 4-NITROANILINE WITH HIGH PURITY AND HIGH YIELD BY USING A NASH REACTION

摘要

PURPOSE: A manufacturing method of 4,4-dinitrodiphenylamines and a manufacturing method of 4,4-bis(alkylamino)diphenylamines are provided to simplify manufacturing process and reducing raw material cost.;CONSTITUTION: A manufacturing method of 4,4-dinitrodiphenylamines comprises a step of reacting 4-nitroaniline and nitrobenzene under presence of base and polar organic solvent. A manufacturing method of 4,4'-bis(alkyl amino) diphenylamine comprises the following steps: a step of manufacturing 4,4'-dinitrodiphenylamines by reacting 4- nitroaniline and nitrobenzene under presence of base and polar organic solvent; and a step of manufacturing 4,4'- bis (alkyl amino) diphenylamine by hydrocracking 4,4'-dinitrodiphenylamine and ketone under hydrogenation catalyst.;COPYRIGHT KIPO 2012
