| 内容記述 | The reactivity of solid silver acetate in hydrogen and oxygen has been studied by using the transient response method and the in situ diffuse reflectance infrared fourier transform spectroscopic (DKIFTS) technique to compare its nature to that of the reaction intermediates in ethylene oxidation. 0n the analysis of the transient response curves, solid silver acetate produced acetic acid and a small amount of carbon dioxide in a hydrogen stream, and produced CO_2 and a small amount of CH_3COOH in an oxygen stream. Temperature programed reaction (TPR) spectra of the two products commonly exhibited a peak temperature of 170℃ in the hydrogen stream and 210℃ in the oxygen stream, indicating that its reactivity in the hydrogen stream should be higher than in the oxygen stream. A possible reaction mechanism has been proposed for both streams. A new IR cell has been developed for the in situ DRIFTS study under transient states, and it was confirmed that the response of the cell to the step change in gas composition was within two seconds. The transient responses of the characteristic absorption bands for the surface species of solid silver acetate, in the H_2 stream or in the O_2 stream, are in good agreement with those from the transient response method. | |||||
