Homogeneous Catalytic Hydrogenation of Carbon Monoxide: Ethylene Glycol and Ethanol from Synthesis Gas

摘要: Publisher Summary This chapter discusses the homogeneous catalytic hydrogenation of carbon monoxide. Because variety catalyst responses to pressure, temperature, promoter levels, concentration, and other factors, a direct comparison activities among different catalysts is not entirely meaningful. In general terms, it can be concluded that rhodium-based have shown highest activity selectivity ethylene glycol. Halide-promoted ruthenium are found possess comparable or even greater overall for synthesis gas conversion under similar conditions, but with rates selectivities glycol product generally lower than rhodium catalysts. Unpromoted show relatively low activities, very Cobalt appear an inherent unpromoted this somewhat limited by temperature stability limit cobalt catalyst. The substantial, especially at higher pressures. also details mechanism certain various systems.
