摘　　要：利用衍生化气相色谱法对黄磷诱发氧化苯酚降解产物进行了研究 在磷酸存在下.以甲醇作酯类衍生化试剂,分别用SE-52和HP-17石英毛细管双柱结合GC-MS进行分离定性定量.黄磷诱发氧化苯酚降解产物以羧酸为主.在反应温度50℃时.表现为一级反应特征.速率常数(K):0.077min^(-1),半衰期(t_(12)):9.0min.The products of phenol by the yellow phosphorus (P4) -oxygen induced oxidation were derivatized by using methanol with phosphoric acid as catalyst ,then were separated and analysed by gas chromatography with two fused-silica capillary columns coated with SE-52 and HP-17 respectively and identified by GC-MS. The main products of the induced oxidation of phenol are primarily carboxylic acids. The oxidation reaction was found to be of first order with respect to phenol, and the reaction rate constant is 0. 077min-1 with half-life of 9. Omin.
