| Abstract | The gas-phase hydrogenation of diethyl malonate to 1,3-propanediol has been studied over Cu/SiO2 nanoparticles. The influence of the ammonia amount was investigated on the catalyst properties and moreover on the hydrogenation of diethyl malonate to 1,3-propanediol in the liquid hourly space velocity of 0.72-1.8 h(-1). N-2-physisorption, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy and H-2-temperature-programmed reduction were used to characterize the textural and structural properties of Cu/SiO2 catalysts. The amount of ammonia played a profound effect on the morphology and the dispersion of copper species. Cu/SiO2 catalyst with the molar ratio of n(NH3 center dot H2O)/n(Cu2+) = 2 gained better dispersion, smaller particle size and less dependence to agglomerate of copper species and thus had a higher selectivity for 1,3-propanediol. |
