摘要:
以赤藓糖醇为原料,利用绿色硝化剂五氧化二氮(N2O5)在硝酸(HNO3)介质中硝解制得1,2,3,4-丁四醇四硝酸酯(ETN)。与现有混酸法相比,该反应可在无硫酸(H2SO4)环境下进行,后处理简单,废酸污染小。试验探讨了投料比、反应温度和反应时间对ETN产率的影响,用扫描电镜SEM、红外光谱IR等对不同ETN晶体的形态进行了表征。结果表明,投料比m(赤藓糖醇):m(N2O5):V(HNO3)=2.5 g :4.0 g :20.0 mL、反应温度为20 ℃、反应时间为2 h时,ETN的产率最高,达76.6%。同时,3种不同晶体形态的ETN具有相同的特征峰。
Abstract:
Erythritol tetranitrate was synthesized from erythritol by nitration in nitric acid (HNO3) medium with green nitrating agent nitrogen pentoxide (N2O5). Compared with the existing mixed acid method, the reaction can be carried out in a sulfuric acid-free environment, with simple posttreatment and less pollution of waste acid. The effects of feed ratio, reaction temperature and reaction time on the yield of erythritol tetranitrate were investigated. The different crystal morphologies were characterized by SEM and IR. The results show that the yield of erythritol tetranitrate reached 76.6% when the ratio of m(C4H10O4):m(N2O5):V(HNO3)=2.5 g:4.0 g:20.0 mL at the reaction temperature of 20 ℃ and the reaction time of 2 h. At the same time, three kinds of erythritol tetranitrate with different crystal morphology have the same characteristic peaks.
