摘要: 用β-环糊精对月见草油进行包络,对包络物作了红外光谱、紫外光谱和差热分析。考察了包络物对重金属离子种类和浓度以及不同温度作用的稳定性。结果表明:随温度的升高和金属离子浓度的增大,油和包络物的吸光度都增加。在120℃温度下反应2.5h,月见草油的ΔA/A0值增加1.69倍,包络物的ΔA/A0值增加1.2倍。0.08mol/LPb2+作用下反应8h,油的ΔA/A0值增加2.29倍,包络物的ΔA/A0值增加0.49倍,由此说明包络物对温度和金属离子作用的稳定性大大提高。

Abstract: The structure of the inclusion complex of Oneothera Biennis oil by β-cyclodextrin was characterized with IR, UV- Vis and differential thermal analysis technique.The influence of the type, concentration of the heavy metal cation and the temperature on the stability of β-cyclodextrin inclusion complex was investigated. The results showed that the absorbance of Oneothera Biennis oil and its inclusion complex by β-cyclodextrin increased with the concentration of metal cation and the temperature. When the reaction was carried out for 2 .5h at 120℃, ΔA/A0 for the two substrates increased to 1.69 and 1.2 times of the original values, respectively. When reacted for 8h at 0.08mol/L Pb2+,ΔA/A0 for the two substrates became 2.29 and 0.49 times of the original values, respectively, indicating a greatly increased stability of the inclusion complex to the variation of the metal cation concentration and the temperature relative to the Oneothera Biennis oil.
