The effect of fluorination on the bonding of alkyl ethers to the Al(110) surface

Temperature-programmed desorption (TPD) has been used to investigate the effect of fluorination on the surface chemistry of several model ethers on the Al(110) metal surface. The model compounds studied were dioxolane ( ▪), diethylether [(CH 3CH 2) 2O], dimethoxymethane [(CH 3O) 2CH 2], dimethylethe...

Zusammenfassung:Temperature-programmed desorption (TPD) has been used to investigate the effect of fluorination on the surface chemistry of several model ethers on the Al(110) metal surface. The model compounds studied were dioxolane ( ▪), diethylether [(CH 3CH 2) 2O], dimethoxymethane [(CH 3O) 2CH 2], dimethylether [(CH 3) 2O] and their fully fluorinated analogs. Perfluorination of these ethers decreases their desorption energies from ∼13 to ∼7 kcal/mol. At coverages in the range 0.1 < θ
