Abstract: Oxidation of 1-butene to butanone in the presence of homogeneous catalyst Pd + HPA (H12P3Mo18V7O85) followed by regeneration of the catalyst with O2 proceeds with selectivity 97.5 %. Side products of the process are acetic acid (1.4 %) and condensed compounds С7Н12О2, С8Н14О2, С6Н6О2, and С8Н10О2 (total 1.1 %). In the course of the catalyst regeneration at 170 °С under O2 pressure, the compounds C6–C8 are completely oxidized to CO2 and acetic acid. n-Butanal is absent in the reaction products, that permits readily to separate butanone as a water azeotrope from the reduced catalyst.
