摘要
本文报告了用对硝基甲苯为原料,经氧化还原反应合成对氨基苯甲醛,再经重氮化,与甲醛肟反应,合成对苯二甲醛的一种新方法,考察了影响产物产率的各种因素,得到了较为满意的结果。
In this paper, a new method of synthesis terrphthalaldehyde is reported. At first P-amino benzaldehyde has been prepared by the redox reastion of P-nitrotoluene which is used as raw material, then terrphthalaldehyde has been got by the diazotization and formaldehyde oxine reaction. Various factors affecting the yields of terphthaladehyde have been studied, the result was satisfactory.
