摘要

The racemization of R-2-amino-1-butanol proceeded effectively over a Co–Rh/γ-Al₂O₃ catalyst in a fixed-bed reactor. The catalyst was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, temperature-programmed reduction, and transmission electron microscopy. For these catalysts, Co⁰ was believed to be the active sites of the catalyst, and the presence of the optimum amount of rhodium led to highly dispersed active species. The activity, selectivity, and stability of the catalyst were demonstrated, and racemic 2-amino-1-butanol was obtained with a yield >82%under the optimum reaction conditions.
