含环己烯基脂环族二元酸酐的制备与性能研究

摘要

以四氢苯酐与氯化偏苯三酸酐为反应物,通过加氢还原和酯化反应两步法合成了一种新型含环己烯基脂环族二元酸酐,并对其进行了结构表征和溶解性研究.红外光谱(FT-IR)与核磁共振(1H-NMR)均证实了目标产物被成功合成,且该二元酸酐在常规有机溶剂中具有良好的溶解性.%A new cyclohexenyl-containing alicyclic dianhydride,cyclohex-4-ene-1,2-diylbis(methylene)bis(1, 3-dioxo-1,3-dihydroisobenzofuran-5-carboxylate)was synthesized by reduction and esterification,starting from tetrahydrophthalic anhydride and trimellitic anhydride acid chloride.FT-IR and 1 H-NMR spectra indicated that the new cyclohexenyl-containing alicyclic dianhydride was successfully performed,and it showed good solubility in several organic solvents.
