摘要
建立了反相键合相液相色谱分析离子液体咪唑类离子液体[bmim]PF6[、bmim]BF4、吡啶类离子液体[bupy]BF4的纯度及其中高沸点有机物的方法.以缓冲溶液控制流动相pH值,显著改善了峰形.保留时间定性,外标法定量.
The reversed--phase high performance liquid chromatographic method for analysis of ionic liquids [bmim] BF4.[bmim] PF6, [bupy] BF4 ＆ high boiling point organics naphthalene, phenanthrene, diphenyl.DBT.Diphenyldisulfide in them. Peak shape was improved by adjusting pH of mobile phase with buffer solutiom. The nature is qualitatively measured by retentive time, and quantitative analysis is carried out by external standard. The series of methods is significant to determine the solubility of high B. P.organics in ionic liquids.
