| 摘 要： | 采用间苯二酚为原料,经过磺化、硝化、水解合成2-硝基-1,3-苯二酚,再用硫酸二甲酯进行甲基化,得到2-硝基-1,3-苯二甲醚。重点讨论了2-硝基1,3-苯二酚及其甲醚化工艺条件,结果表明,使用质量分数20%发烟硫酸可使1,3-苯二酚全部二磺化从而使2-硝基1,3-苯二酚收率增至63.5%,色谱纯度达98.5%以上;在反应温度80℃,反应时间4 h,n(M e2SO4)∶n(2-硝基1,3-苯二酚)=2.2∶1.0时,2-硝基-1,3-苯二酚甲基化收率高达75.6%。

| Abstract: | 2-Nitrobenzene-1,3-diol was obtained through a series of physical and chemical processes containing sulfonation,nitration,and hydrolysis etc.and treated with dimethyl sulfate to give 1,3-dimethoxy-2-nitrobenzene.It has been shown by investigating various technological conditions mentioned above that resorcinol can be completely two-sulfonated and finally resulting in 2-nitrobenzene-1,3-diol with the yield of 63.5% and the contents over 98.5% when 20% of oleum used as sulfonation reagents and 1,3-dimethoxy-2... |
