N,N,N′,N′-四苯基联苯胺的合成新方法

A new synthesis method of N,N,N′,N′-tetraphenylbenzidine

以联苯胺和二苯胺为原料 ,经两步反应合成了 N,N,N′,N′-四苯基联苯胺 (TPB)。与已报道的方法相比较 ,该方法具有产率高、操作简单。

A new synthesis method of N,N,N′,N′ tetraphenylbenzidine(TPB),which uses commercial benzidine and diphenylamine as the raw materials,was developed Compared with previous TPB′s synthesis method,the new one has the advantages of high yield,easy handling and cheap raw material
