摘要
在1,2-二氯乙烷溶剂体系下对萘硝酸硝化制备二硝基萘的工艺进行改进。优化实验表明,1,2-二氯乙烷作溶剂,n(萘)∶n(硝酸)为1∶6,硝酸的质量分数为95%,反应时间达到2.0h,反应温度为40℃,可获得高选择性的1,8-二硝基萘混合物,含量达到64%。
The improved synthetic processes of dinitronaphthalene in 1,2-dichloroethane solvent were discussed in the present paper.Under the optimization nitrification condition such as using 1,2-dichloroethane as solvent,the1∶6of the mole ratio of naphthalene to nitric acid（95%,w）,and the 40℃ of reaction temperature,the 2hof reaction time,the contenet of 1,8-dinitronaphthalene is as high as 64%.
