摘要：

A small flow reactor (5 ml volume) is used for continuous hydrogenation in supercritical CO2 or propane with polysiloxane-supported noble metal catalysts; a wide range of organic functionalities can be hydrogenated with good throughput (up to 1200 ml h(-1) in favourable cases) and the various parameters (temperature, pressure, concentration of H-2, etc.) can be controlled independently to optimise the selectivity for a particular product.
