Route of Synthesis (ROS)
| Conditions | Yield |
| With carbon monoxide In neat (no solvent) passing CO over RuO2, heating; | |
| In neat (no solvent) heating at 1400 °C, cooling; | |
| With hydrogen at 200℃; for 4h; α-aluminium oxide; Experimental Procedure 300 g of a used catalyst comprising 2percent by weight of RuO2 on α-aluminum oxide as support was reduced in a stream of hydrogen at 200° C. in a rotary tube furnace for 3 hours. Here, the catalyst was firstly heated to 200° C. in a stream of nitrogen, and was then reduced in a stream of N2/H2 (5:1) for 1 hour and subsequently in pure H2 for 3 hours. The reduced catalyst was dispensed under a nitrogen atmosphere into a vessel into which nitrogen was passed. The reduced catalyst was subsequently transferred under a nitrogen atmosphere into a 2000 ml stirred apparatus and 1160 g of 32percent strength by weight hydrochloric acid were added. While stirring and introducing nitrogen, the mixture was heated to 100° C. The mixture was subsequently stirred at 100° C. while sparging the solution with 50 l/h of air for 24 hours. A dark red ruthenium chloride solution was obtained and this was decanted off from the residue. The support which remained as residue was washed with about 1 l of water until neutral. The support was subsequently dried at 120° C. for 16 hours and the ruthenium content of the support was determined. The determination indicated a ruthenium content of 0.20percent by weight. In comparison, the used catalyst comprised 1.49percent by weight of ruthenium. Thus, about 13percent of the originally comprised ruthenium remained on the support. | |
