| Abstract: | 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. |
