在强碱条件下合成2－硝基－2′－羟基－3′，5′－二叔丁基偶氮苯

THE HIGH CAUSTIC COUPLING PROCESS OF 2-NITRO-2′-OHYDROXY-3′,5′-DI-(TERT-BUTYL)AZOBENZENE

本文通过实验论述了在强碱条件下合成２－硝基－２′－羟基－３′，５′－二叔丁基偶氮苯的过程。ｐＨ＞１３，Ｔ＝－２℃可得到最佳收率。

This paper expounds through experiment the high caustic coupling process of 2-nitro-2′-ohydroxy-3′,5′-di-(tert-butyl)azobenzene. For pH >13 and T=-2℃,the optimum recovery ratio can be obtained.
