摘　　要：介绍了以对硝基乙苯为原料 ,经三氯异氰脲酸氯化反应、碱解反应和酸化反应 ,高纯度 (大于 99% )、较高收率和较低成本地合成了目的产物的方法。Dichloro-3-ethyl-6-nitrophenol which is the important intermediate to form developer in color photograph was prepared, using p-nitroethylbenzene as the start material .Through TCIA chlorination ,alkalization, and acidification reaction, the target product was gain with high purity(99%), high yield, and low costs. The amount of the chlorination agent charged into the reaction and preparation process can be controlled easily.
