Comparison of the Chemistry of ClCH2CH(CH3)OH and ClCH2CH2CH2OH on Cu(100) and O/Cu(100)

摘要: Thermal reactions of bifunctional 1-chloro-2-propanol and 3-chloro-1-propanol on Cu(100) oxygen-precovered are presented in this article. X-ray photoelectron spectroscopy, reflection–absorption infrared spectroscopy temperature-programmed reaction/desorption have been employed to investigate the decomposition process Cu(100). The competitive dissociation functional C–Cl CO–H at 265 K results formation ClCH2CH(CH3)O– −CH2CH(CH3)O– surface intermediates a 2:1 concentration ratio. This ratio decreases ∼0.6:1 300 K. oxametallacycle is theoretically predicted be bonded surface, with both O CH2 bridge sites. intermediate decomposes mainly producing CH3C(O)CH3 CH3CH═CH2 addition H2 CO. Preadsorbed oxygen atoms can stabilize increases its reaction temperature ∼350 Moreover, propene promoted relative acetone. In ...
