马来酸衍生物的合成及其凝胶性能的研究

Synthesize of Maleic Acid Derivatives and their Gelation Ability

以马来酸酐和十二胺为原料,利用酸酐的氨解反应,合成了马来酸衍生物,这种衍生物是同时具有羧基和酰胺基团的长链有机小分子凝胶因子,利用1 H-NMR和13 C-NMR对其进行了表征,结果表明,产物结构与理论结构相符合。通过加热溶解-冷却静置以及倒置法测试了其凝胶性能。实验结果表明,有机小分子凝胶因子可在多种有机溶剂中形成凝胶,并且具有热可逆性。同时研究了有机小分子凝胶因子在凝胶中可能的自组装形式,初步提出了有机小分子凝胶因子在胶凝化过程中的机理。

Low-molecular-mass organic gelator（LMOG）N-octadecyl succinic acid was synthesized from succinic anhydride and octadecylamine by ring-open reaction.The structure of gelator was confirmed by ^1H-NMR and ^13C-NMR.The gelation ability was inspected by a typical experiment including heating-cooling to form gel and inverting the test tube without deformation of the gel.The results indicate that the N-octadecylcotadecylamine can form the oreticalorganogels in different organic solvents.The self-assemble in the organogel was studied and a preliminary gelation mechanism was proposed.
