| 摘 要： | 本文报导了15℃时乙烯在Pd/SiO2上化学吸附的红外光谱。表面吸附物加氢后的气相产物是乙烷和少量的丁烷。实验表明乙烯在Pd/SiO2上化学吸附产生了三种表面种:即σ键型的表面种PdCH2CH2Pd、由自加氢和二聚作用形成的正丁基表面种CH3CH2CH2CH2Pd和由解离吸附产生的表面碳化物。

| Abstract: | Infrared spectra of ethylene chemisorbed on silicasupported palladium at 15℃ have been obtained.On hydrogenation of the chemisorbed surface species at 15℃, ethane and a smaller amount of n-butane were formed.The experiment indicated that ethylene chemisorbed on silicasupported palladium formed three surface species: the σ-bond type surface species PdCH2CH2Pd; the n-butyl type surface species CH3 CH2 CH2 CH2 Pd, probably via a self-hydrogenation and surface dimerization; and the surface carbide probably via the dissociative chemisorption of ethylene. |
