摘要
采用气相色谱对双氧水氧化苯制苯酚反应体系中苯、苯酚的含量进行测定。给出了含量测定的具体方法。由于同一检测器对不同物质具有不同的响应值,采用校正面积归一法。以苯为参考峰,测得苯酚的相对校正因子为1.4625。同时,给出了反应过程中苯转换率及苯酚选择性的计算方法。
The fraction of benzene and phenol in the direct oxidation of benzene using hydrogen peroxide was determined by GC. Because of the different response value between benzene and phenol, the method of correction area was used. With benzene as the reference, relative correction factor of phenol was 1. 4625. The methods of calculating the turn- over of benzene and the selectivity of phenol were also elaborated.
