摘要
研究了β-环糊精与苄基甲基酮主、客体分子的包合反应。通过红外、热重-差热、X-射线衍射、核磁共振及元素分析方法确定了包合物的形成与组成。包合物明显改变了主、客体的晶相、光谱及热学性质。核磁共振及元素分析结果表明:β-环糊精与苄基甲基酮形成了包合比(主、客体的物质的量之比)为2∶1的包合物,苄基甲基酮的苄基及甲基分别嵌入了两个β-环糊精的空腔。
An inclusion compound of benzyl methyl ketone （BMK） with β-cyclodextrin （β-CD） was synthesized and characterized by FT-IR, XRD, TG-DTA, elemental analysis and ^1HNMR spectra. The experimental results showed that β-CD formed 2 ： 1 host-guest compound with BMK. The molecular structure of the inclusion compound suggested that the benzyl and methyl parts of BMK molecule penetrated into two hydrophobic cavity of β-CD respectively.
