Abstract
Abstract Silica-supported Cu (Cu/SiO2) catalyst prepared by using organic additive-assisted impregnation was employed for the chemoselective hydrogenation of a C=O bond in 6-methyl-5-hepten-2-one (1) to produce 6-methyl-5-hepten-2-ol (2) in a vapor phase at a temperature between 140 and 200 °C and an ambient pressure of H2 flow. The Cu was responsible for the selectivity to 2, and the organic additive increased the Cu surface area (SACu), which consecutively enhanced the performance of the Cu/SiO2 catalyst. The proportional correlation between the SACu and the formation rate of 2 further confirmed the benefits of the utilization of organic additives during the impregnation protocol.
