| Abstract: | The external standard method for determining the reaction product distribution of direct oxidation of benzene to phenol was studied by using gas chromatography. And the gas chromatographic conditions were optimized. The experimental results show that the optimal chromatographic conditions are as follows： the vaporizer temperature 290 ~C, the detector temperature 320 ℃, the heating rate 5 ℃/rain, the flow rate of carrier gas 2.0 mL/min, the split ratio 120：1, and the injection volume 1 gL. The standard sample recovery rate is 95% -105% basing on the external standard method. The maximum relative standard deviation of repeatability is 1.62%. |
