摘    要:甘脲具有双环双脲结构,既是质子给体,又是质子受体,能与溶质产生氢键作用等多种作用力。本文制备了以甘脲作为固定相的填充柱,并对它的色谱性能进行了研究。结果表明:甘脲固定相热稳定性高、柱性能稳定,是一种良好的气相色谱固定相。该固定相对烷烃、卤代烃、芳烃、醇、酯、酮、酸、胺等类物质具有良好的分离能力,尤其是对位置异构体(如二取代苯位置异构体)有较好的分离选择性。本文还初步探讨了甘脲固定相的分离机理。

关 键 词:甘脲  葫芦脲  填充柱  气相色谱  固定相

Abstract:Glycoluril possess two annuli diurea structure,can provide various binding sites for analytes such as hydrogen-bonding interaction etc.In this paper,Glycoluril was used as stationary phase in packed column gas chromatography for the first time.Its chromatographic properties were studied by using different probes.The results showed that the glycoluril was a good GC stationary phase with wide operational temperature,outstanding thermostability and good separation ability for alkanes,halohydrocarbons,aromatic hydrocarbons,alcohols,esters,ketones,carboxylic acids and amines,etc.It was also found that some positional isomers such as disubstituted benzene can be well separated on the column.The mechanism of the GC-separation was preliminary discussed.
Keywords:Glycoluril  Cucurbituril  Packed column  Gas chromatography  Stationary phase
