Title
Selective hydrogenation of 3,3-dimethylbutanoyl chloride to 3,3-dimethylbutyraldehyde with silica supported Pd nanoparticle catalyst
Abstract

A novel method for selective hydrogenation of 3,3-dimethylbutanoyl chloride (DMBC) to 3,3-dimethylbutyraldehyde (DMBA) with silica supported Pd nanoparticle catalyst (Pd/SiO2) is developed. The catalysts were characterized by Fourier transform infrared spectroscopy, X-ray powder diffraction, N2 physisorption and transmission electron microscopy. The performance of the Pd/SiO2 catalyst was compared with Pd/C and Pd/BaSO4 catalysts with or without being pretreated by quinoline–sulfur. The Pd/SiO2 catalyst activated at 80 °C by bubbling hydrogen in cyclohexane for 1 h showed the highest yield of DMBA. For 3 wt.% Pd/SiO2, the yield of DMBA reached 84.6%, which exhibited much higher value than Pd/C and Pd/BaSO4 catalysts.
