General description
柠檬酸酐是马来酸酐的衍生物，也称为2-甲基马来酸酐。由于酸酐基团的存在，它具有高活性，可以进行水解、酯化、酰胺化和加成反应。 它可以作为交联剂，在聚合物链之间形成共价键，提高聚合物网络的机械强度和热稳定性。它们是生物偶联和生物活性分子固定的潜在工具。
Application
柠檬酸酐可作为：
- 高温袋式锂离子电池的电解质添加剂。柠檬酸酐降低了袋状电池在高温贮存过程中的界面阻抗，提高了袋状电池的稳定性。
- 作为一种pH敏感连接剂，用于药物输送系统生物分子的表面功能化。柠檬酸酸酐偶联物的高pH敏感性是由于其双键的存在限制了酰胺和羧基之间的分离。
- 作为试剂，通过杂-Diels–Alder反应合成新的硫代吡喃[2,3-d][1,3]噻唑衍生物。这些硫代吡喃衍生物具有多种生物活性，如抗癌、抗病毒和抗锥虫。
- 作为共聚单体与d-木糖3,5-无水糖衍生物开环聚合，形成新型糖源聚酯，可再生含量高达100%。 可以作为聚合物合成的可持续原料。
