Abstract

A fully integrated continuous process for homogeneous catalysed reactions in scCO2 has been developed exploiting the tunable solvent properties of scCO2. A heated condenser situated above the reaction zone leads to a phase split under isobaric conditions resulting in efficient catalyst retention and recirculation. Continuous isomerisation of allylic alcohols was carried out for over 200 hours time-on-stream demonstrating the viability of this approach.
