| 摘 要： | 利用GC法建立了对羧基苯甲醛 ( 4CBA)的分析方法。试验发现 ,选用对苯二甲酸二甲酯为内标物 ,乙醇为溶剂 ,4CBA色谱峰面积与内标物色谱峰面积之比A( 4CBA) /A(内标物 )与 4CBA含量之间有很好的线性关系 ,得出了计算方程 ,相关系数达到 0 9982。同时 ,对反应体系中的 4CBA进行在线取样分析和回收试验 ,结果令人满意。并且对 4CBA的化学不稳定性用IR和GC方法进行了表征

| Abstract: | A new method has been developed to determine the content of 4CBA using GC.There is a good relationship between 4CBA content and its GC peak area when alcohol is used as solvent and terephthalic acid dimethyl ester as internal standard.Determination of 4CBA content in a specific reaction system is conducted to test Pd/C catalyst activity.Results including recovery are satisfactory.Initial study about 4CBA′s chemical instability using IR and GC has also been carried out. |
