Continuous hydrogenation of organic compounds in supercritical fluids

Abstract: A small flow reactor (5 ml volume) is used for continuous hydrogenation in supercritical CO 2 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 21 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.

“…In this case, however, a liquid phase occurred. Using commercial palladium or platinum Deloxan (aminopolysiloxane, trademark of Degussa) catalysts, the hydrogenation of various organic substances like cyclohexene and acetophenone was studied in supercritical CO 2 [54]. Hydrogenation of cyclohexene proceeded much more rapidly and selectively than the analogous reaction in the gas phase.…”

“…A complete conversion was reached within a few seconds, as the reaction rate was not limited by phase boundaries [39][40][41]. Hydrogenation of cyclohexene [42] and other organic substances in supercritical propane was successful when using Pd/deloxane as a catalyst [43].…”
