| 摘 要： | 利用乙酰丙酸和苯酚缩合反应制取双酚酸（DPA）,并采用红外光谱及核磁光谱对其结构进行了表征。研究了DPA在水、乙腈、甲醇和环己烷4种溶剂中的紫外光谱。结果发现,在这4种溶剂中,DPA溶液的紫外光谱主要在210nm左右及260nm左右有两个强吸收峰。210nm左右的吸收峰对溶剂的极性及溶液的浓度敏感。而260nm左右的吸收峰在各种极性不同的溶剂中的位置变化不明显,对溶液浓度也不敏感。因此,DPA在260nm吸收峰可以用于DPA的定量分析,而210nm吸收峰可用于研究DPA与其他分子的相互作用。另外,溶剂极性对两个吸收峰强度的影响也不相同。

| Abstract: | Diphenolic acid was prepared by condensation reaction of levulinic acid and phenol,and was characterized by IR and NMR.Moreover diphenolic acid solutions in four different solvents(water,acetonitrile,methanol,cyclohexane) were studied by ultraviolet spectra.There were two strong absorption peaks around 210nm and 260nm,respectively.The absorption peak around 210nm was sensitive to the polarity and concentration of the solvent.However,the absorption peak around 260nm remained basically stable when the polarit... |
