摘要:
β-环糊精和辛烯基琥珀酸酐为主要原料,通过湿法制备工艺合成辛烯基琥珀酸糊精酯。本研究通过单因素试验、正交试验,探讨反应温度、pH值、反应时间、糊精乳质量分数等因素对辛烯基琥珀酸糊精酯取代度的影响。结果表明,辛烯基琥珀酸糊精酯最佳制备工艺条件为:反应温度35 ℃,pH值8.0,反应时间4 h,糊精乳质量分数35%。采用傅里叶红外光谱分析仪、热重分析仪对最佳工艺条件下合成的辛烯基琥珀酸糊精酯进行结构表征。红外光谱分析结果显示:辛烯基琥珀酸糊精酯在1 723、1 572 cm-1处均出现了新的吸收峰,分别由酯基、碳碳双键伸缩振动产生。热重分析结果表明:酯化反应形成的辛烯基琥珀酸糊精酯结构稳定性更强。
