1,4-双(3,4-二羧基苯氧基)苯二酸酐的合成与表征
Synthesis and characterization of 1,4-bis(3,4-dicarboxylphenoxy) benene dianhydride
【摘要】 以4-硝基邻苯二甲酰亚胺为原料,经过五步反应,即氨解、脱水、取代、水解和脱水合成了一种双醚酐单体1,4-双(3,4-二羧基苯氧基)苯二酸酐。研究了反应条件对产率的影响。用IR,1H-NMR表征了1,4-双(3,4-二羧基苯氧基)苯二酸酐及其他中间体化合物的结构。
【Abstract】 A bis(ether anhydride) monomer,1,4-bis(3,4-dicarboxylphenoxy)benene dianhydride,was synthesized from 4-nitrophthalimide through 5 steps: aminolysis,dehydration,displacement,alkaline hydrolysis and dehydration.The effects of reaction conditions on yields were investigated.The structure of 1,4-bis(3,4dicarboxyphenoxy)benzene dianhydride and other intermediates were confirmed by IR,1H-NMR spectra.
