摘要
用一步微量萃取法预处理对甲酚氧化制对羟基苯甲醛反应液样品,然后进行气相色谱分析,考察了色谱分析条件和影响因素。
A onestep microextraction method was developed for pretreatment of reactant liquor of p-cresol oxidation process for preparing p-hydroxybenzoldehyde,and the treated sample was analysed by gas chromatagraphy.The corditions for gas chromatagraphic analysis and effect factors were investigated.
