| Summary: | 碩士 === 元智大學 === 化學工程與材料科學學系 === 96 === The purpose of this study is focus on the kinetics of the selective oxidation reaction of ethylene glycol catalyzed by Au/C catalyst. Factor such as the type of catalyst, amount of catalysts added, temperature, ethylene glycol recruitment, and concentration of NaOH were investigated in this work.
Results showed that Au/C has the best activity and glycolic acid selectivity for ethylene glycol selective oxidation reaction amount catalysts of Au/C(WGC), Pt/C(E-tek), Pd/C(home-made) and Au sol. Further, the reactivity for is fond to be proportion to the amount of Au/C added in the range of 0.0016g/L~0.016g/L. The reactivity for is fond to be inverse proportion to the amount of ethylene glycol added in the range of 10mM??100mM. From the different concentration of NaOH, best the reactivity for is fond to be proportion to the concentration of NaOH added in the range of 0~81.63mM.
