一种新型气相色谱固定液的制备及应用

Study and Apply of a New GC Stationary Liquid

以柠檬酸、OP-10和二乙醇胺为原料合成了柠檬酸壬基酚聚氧乙烯醚单酯二乙醇酰胺。用红外光谱法表征了结构,热分析技术考察了热稳定性。以此产物作为气相色谱固定液,对一些混和组分进行分离,效果良好。

The citric acid polyethyleneoxide ether amber diehylene glycol dinitrate diglycollic amid was synthesized by the citric acid and the polyoxyethylene nonyl phenyl ether and the diethanolamine. The structure of the product was determined by IR spectrum. The thermal stability was investigated via thermogravimetry analysis（TG）. The surfactants could be used as gas chromatographic stationary liquid, the good behavior of the stationary liquid was showed by separation efficiency to some component in mixture samples.
