Abstract
Ru(III) ions have been incorporated in the domains of sulfonated linear polystyrene (PSSA) as a dispersion medium to form PSSA-Ru(III) films through an ion-exchange process. The chemical reactivities of PSSA-Ru(III) films have been investigated by reacting the ruthenium sites with CO, H 2, O 2, CH 3OH, and C 2H 5OH under mud conditions. The reactions of PSSA-Ru(III) films with CO (400 Torr) in the temperature range 25–186 °C resulted in four different Ru carbonyl species, which were characterized by their infrared spectra. Treatment of PSSA-Ru(III) films with hydrogen (400 Torr) at 150 °C produced ruthenium hydride species, which were confirmed by identifying the corresponding ruthenium deutendes. Also, HD exchange on benzene rings of the polystyrene backbone was found to occur during the reaction of PSSA-Ru(III) films with D 2. The reactions of aqueous methanol and ethanol with PSSA-Ru(III) films produced ruthenium carbonyl species, but there was no evidence of the formation of ruthenium hydride or ruthenium formyl groups in the infrared spectra. Static Fischer-Tropsch type reactions of PSSA-Ru(III) powder with CO (300 Torr) and H 2 (300 Torr) at 150 °C showed the formation of various aliphatic hydrocarbons, oxygen-containing hydrocarbon compounds, and CO 2 in the mass and infrared spectra.
