The catalyst of 5%ZnO-3%MgO/SiO2 was prepared by impregnation method.The pure oxygen as the oxidation,2-ethylhexanoic acid was synthesized directly from 2-ethylhexanol at atmospheric pressure.Catalyst dosage,oxygen flow,reaction temperature and time were optimized,and the best process condition was determined.The result indicated that the conversion of 2-ethylhexanol and the selectivity of 2-ethylhexanoic acid up to 63.6% and 75.4%,respectively were achieved under the following conditions that the 2-ethylhexanol dosage was 50 mL,the catalyst dosage was 2.5 g,the oxygen flow was 30 mL/min,reaction temperature was 125 ℃,and reaction time was 9 h.
