실험 절차

The experiment was carried out without the addition of vanadium to check its effect on the conversion and selectivity in the liquid phase oxidation of toluene with following the procedure given in Example 1. The reactor was charged with toluene 10.0 gm, manganese acetate 0.262 gm, sodium bromide 0.065 gm and acetic acid 50.0 gm. After flushing with nitrogen, 5% oxygen was introduced to a pressure of 55 bar and the reaction was carried out at 120° C. In this experiment, 10.2% toluene conversion and 61.4%, 16.4% and 22%, selectivity was obtained for benzaldehyde, benzoic acid and benzyl alcohol, respectively.
