An Integrated Process of H2O2 Production through Isopropanol Oxidation and Cyclohexanone Ammoximation

The possibility of the integration of the processes of H2O2 production through isopropanol partial oxidation and the direct ammoximation of cyclohexanone with H2O2 and NH3 catalyzed by TS‐1 was investigated. The results of isopropanol partial oxidation showed that around 7.5 % yield of H2O2 was obtained at 110 °C, 10 atm, 2 h, and after fractionation, a H2O2 solution with the typical composition 25.2 wt.‐% H2O2, 10.3 wt.‐% isopropanol, 0.29 wt.‐% acetone, 0.45 wt.‐% phosphoric acid and 0.43 wt.‐% acetic acid was obtained. The presence of these impurities up to the above levels did not appreciably influence the ammoximation of cyclohexanone in terms of the conversion of cyclohexanone and the selectivity to cyclohexanone oxime. The results indicate that the processes of H2O2 production through isopropanol partial oxidation and the ammoximation of cyclohexanone can be integrated.
