摘要
研究了萘在硝酸/醋酸酐体系下选择性硝化,以发烟硝酸(95%)为硝化试剂,乙酸酐作为反应溶剂。最佳反应条件是:萘0.51g(4mmol)、乙酸酐(5.00mL)、催化剂CdZSM-5 0.10g、发烟硝酸0.27mL(6mmol),冰浴下搅拌反应,～硝化物回收率73.84%,1-硝基萘与2-硝基萘异构体的比值为3.93。目标产物用红外光谱和核磁共振表征。
The selective synthesis of nitronaphthalene was studied in this article. In the nitration systems of fuming nitric acid and acetic anhydride, the optimum reaction conditions：fuming nitric acid （0. 27mL）, acetic anhydride （SmL）, CdZSM-5 （0. 10g） were stirred at 0℃, then naphthalene （0.51g） was added. The yield of mononitronaphthalene was 73.84% and the 1-： 2-nitronaphthalene isomer ratio is 3.93. The structure of the tar^zet product is characterized by ^1H-NMR,IR.
