| Zusammenfassung: | The invention discloses a method for synthesizing m-methylthio diphenylamine, which comprises the following steps: 1) Ullmann condensation: 3, 3'-dimethylthioacardite and halogeno-benzene are subjected to Ullmann condensation reaction under the action of a catalyst and an acid-binding agent to obtain a condensation product; and 2) hydrolysis: the condensation product is subjected to hydrolysis reaction in alkali solution to obtain a crude product of the m-methylthio diphenylamine. The method for synthesizing the m-methylthio diphenylamine has the characteristics of simple process, low cost, environmental protection and high yield. |
