采用气相色谱法 ,以甲酸甲酯为内标物 ,对在所研制催化剂作用下氧化反应前后的醋酸丁酯、二甲苯和苯进行了一次定量分析。色谱条件为 10 % PEG- 2万 10 1白色硅烷化担体 ,2 m× 3 mm色谱柱 ,柱温 110℃ ,检测温度 130℃。得到苯、醋酸丁酯、二甲苯和内标物的保留时间分别为 1.13、3.45、4.47和 2 .5 2 (m in) ,方法回收率 97.4%～ 10 1.84% ,线性相关系数大于 0 .980。结果表明 ,方法简便、准确、快速 By gas chromatography, methyl formate as the internal standard, the catalyst under the action of the oxidation reaction before and after the butyl acetate, xylene and benzene were a quantitative analysis. The chromatographic conditions were 10% PEG-200 10 1 white silanized support, 2 m × 3 mm column, the column temperature was 110 ℃ and the detection temperature was 130 ℃. The retention times of benzene, butyl acetate, xylene and internal standard were 1.13,3.45,4.47 and 2.52 (m in) respectively, and the recoveries were 97.4% -10.104%. The linear correlation coefficients were greater than 0.980 . The results show that the method is simple, accurate and rapid
