Fabrication of Microreactor Using Glass Capillary with Cu/SiO2 Layer

A catalytic reactor using a capillary column with Cu/SiO 2 layer on its inner surface was prepared by injecting a silica sol containing Cu ions in a fused silica capillary and by subsequent gelation under the conditions controlled in order to deposit silica gel uniformly on the inner wall of the capillary. Its catalytic activity was demonstrated in the hydrogenation of propene by constructing a pulse reactor using the catalyst capillary and a separation capillary with pure silica gel layer.
