摘要
本文对间苯二胺的重氮化方法进行了系统的研究，通过实验得出了两种较理想的间苯二胺双重氮化方法。按本文提供的方法用间苯二胺经重氮化反应制备二氟硼酸间苯二重氮盐其收率可达９０％。
In this paper,two fine technology processes have been provided for preparation of m phenylenediazonium difluoborate.m Phenylenediazonium difluoborate can be obtained in 90% yield by diazotization of m phenylenediamine according to these two technology processes. Thermal decomposition of the above diazo solt gives m difluorobenzene in 80% yield.
