Chitin benzoic acid esters were prepared using a phosphoryl mixed anhydride method. The products were characterized by 1H-NMR and FT-IR spectroscopy. FT-IR analysis revealed that the degree of O-acyl substitution of the products was in a range of 1.17-1.83. Morphological surface changes in the parent molecule due to the introduction of benzoic acid moieties were observed by scanning electron microscopy. The surface of the products was porous, in contrast to the sheet-shape of the parent molecules. The solubility of the products, which improved with increased degree of acid substitution, was tested in various organic solvents.
采用磷酰混合酸酐法制备了几丁质苯甲酸酯。通过 1H-NMR 和 FT-IR 光谱对产物进行了表征。FT-IR 分析表明，产物的 O-酰基取代度在 1.17-1.83 范围内。通过扫描电子显微镜观察到由于引入苯甲酸基团而导致母体分子的形态表面变化。与母体分子的片状形状相比，产物的表面是多孔的。测试了产物在各种有机溶剂中的溶解度，随着酸取代度的增加而提高。
