多功能基和氮杂冠醚键合固定相的制备与鉴定

在全多孔微粒硅胶表面进行连续固－液相反应，制备氯丙基（ＣＰＳ）、乙二醇氨丙基（ＤＥＡＰ）、３－［氮杂１８－冠－６］－丙基（ＢＣＰ）键合固定相。采用有机元素分析、功能基分析、热分析、红外光谱和金属离子络合容量测定等对键合相进行鉴定和表征。化学和仪器分析结果表明，键合反应按预定路线进行。键合固定相具有各种色谱性能，其极性效应对分离选择性起重要作用。

Preparation and Charaterization of Multifunctional and Azacrown Ether Bonded Phases

hree polar phases,3-chloropropyl,3-(dihydrodiethylamino)propyl,3-(aza-18-c-6)propyl bondedphases were prepared via solid-liquid phase reaction on the surface of porous silica. Organic element and func-tional group analysis,infrared spectroscopy,thermal analysis and determination of complexing capacity formetal ion,etc. were used for identification and characterization of bonded phases. The results of chemicaland instrumental analysis showed that the bonded reaction was accomplished according to the pathway pre-scribed.The bonded phases have various chromatographic behaviors. The important effect of polar interac-tion on the retention and separation selectivity for the solutes in HPLC was observed.
