| Outline of Final Research Achievements |
In the catalytic liquid-phase oxidation, dissolution of gaseous oxygen may be the rate determining step. In the present study, the heterogeneous and homogeneous catalytic oxidations in a liquid phase wers examined using a micro reactor, in which the slug flow can be easily formed. The slug flow has an advantageous property, in which the rate of the dissolution of gaseous oxygen is enhanced. As an example obtained in the present study, in the oxidation of ethyl lactate to the ethyl pyruvate using VOCl3, that is, homogeneous catalytic system, the yield of ethyl pyruvate was enhanced by 8% on using the microreactor. In the palladium catalyst system for the liquid phase oxidation, the doping of the palladium catalyst with heavy metals is sometimes needed due to a lack of oxygen in the liquid. However, the results obtained in the present reaction indicates that doping of palladium catalyst with heavy metal is not needed in using the micro reactor.
