Abstract
Oxidation of ethyl lactate to pyruvate was carried out in vapor-phase over various oxides. MoO3 showed a higher selectivity than that of the other single oxide examined. Binary oxides containing molybdenum such as Fe2O3-MoO3 and TeO2-MoO3 showed high selectivities to pyruvate ove r 90% at 300-degrees-C with high lactate conversion over 75%. The maxi mum activity on SnO2-MoO3 Was observed at a low temperature of 250-deg rees-C.
