Significance

A novel gold-immobilized capillary column reactor for the oxidation of alcohols with molecular oxygen was described. The authors selected a polysiloxane-coated capillary column (50 cm length, 250 µm inner Æ), which contained 50% phenyl and 50% n-cyanopropyl functionalities on silicon atoms with a film thickness of 0.25 µm on the walls of the microchannel. The oxidation of alcohols using the gold-immobilized capillary column reactor led to the corresponding carbonyls in 90 s of the mean residence time.
