一般描述

乙醇钠（乙酸钠）是一种醇钠。它是由钠与乙醇反应合成的。在水存在下发生分解，生成乙醇和氢氧化钠。它被广泛用作有机合成研究的强碱。

应用


  • 木质素解聚过程中的有机溶剂分馏：研究重点关注如何采用二元非质子溶剂体系提高木质素解聚过程中单酚类物质的产率，以及采用乙氧化钠进行有效的有机溶剂分离。该方法强调了乙氧化钠在复杂有机合成和生物质加工中的多功能性（Xu et al., 2024）。

  • 固态抗自淬硫点：硫点的研究采用溶剂型钝化策略来控制固态抗自淬特性，其中乙氧化钠在合成过程中起着至关重要的作用。该研究说明了乙氧二钠在先进材料合成中的实用性，特别是在光电应用方面（Wu et al., 2022）。

  • 缓蚀剂的合成：乙氧基钠已用于高效合成6,7-二氢- 5h -环戊[b]吡啶-3-碳腈化合物，证明了其作为碱在合成钢合金缓蚀剂中的适用性。该应用程序结合了计算和实际方法，突出了乙氧基钠在材料科学和防腐中的作用（Abd El-Lateef et al., 2022）。

  • 结肠靶向给药系统：采用乙氧化钠设计合成了噻吩[2,3-b]吡啶-壳聚糖结肠靶向纳米复合材料。该研究展示了乙氧二钠在靶向给药系统制备中的应用，重点关注提高药物治疗的疗效和特异性（Mansour et al., 2020）。

  • 抗菌化合物的合成：乙氧基钠是合成新型双α、β -不饱和酮和烟腈衍生物中不可或缺的一部分，旨在抗菌应用。该研究强调了化合物在开发新的抗菌剂中的关键作用，证明了其在药物化学中的效用（Altalbawy, 2013）。
