摘　　要：建立了以正癸烷为内标物,采用气相色谱法对离子液体催化合成环己基苯的反应液进行定量分析方法.分别绘制了苯和环己基苯的标准曲线,相关系数均在0.999以上.分析结果表明：苯和环己基苯含量测定的相对误差不超过5.2%,回收率在97.96%~105.13%之间,苯和环己基苯的精密度分别为1.60%和1.62%.该定量分析方法稳定可靠,符合检测要求.A qualitative method to determine cyclohexylbenzene content in alkylation reaction solution cata- lyzed by ionic liquid was developed, with gas chromatogram and n-decane as internal standard material. The correlation coefficient of standard curves of benzene and cyclohexylbenzene are both more than 0. 999. The analysis result shows that the relative deviations between real values and measured values of benzene and cycly- hexylbenzene are less than 5.2%, recoveries range from 97.96 % to 105.13% , and precision are 1.60% and 1.62% , respectively, which shows high stability and reliability.
