Fine Structure of the Temperature Programmed Reaction Spectra of Silver Acetate Visualized by a Mass Spectrometer
application/pdfThe Temperature Programmed Reaction (TPR) spectra of solid silver acetate were finely visualized by using a mass spectrometer assisted by a personal computer. The TPR spectra obtained exhibited only two products, CO_2 and CH_3COOH. The population and the TPR spectra-pattern of the two products were sensitively affected by the rate of temperature rise and the gas atmosphere, in O_2, He or H_2, indicating the different reaction mechanisms depending on were commonly produced in O_2 or He. For the formation of CO_2 four different reaction intermediates were presumed, whereas for the formation of CH_3COOH in O_2, He and H_2, two reaction pathes would be presumed to supply active hydrogen for the hydrogenation of silver acetate. The activation energy to form CO_2 was evaluated to be 32±4 kcal/mol in He, which shifted extremely depending on the gas atmosphere.departmental bulletin pape
