    • As recently remarked by R. Gläser, R. Jos, J. Willardt, Topics in Catal. 2003, 22, 31, a critical point can only be defined for a single-component fluid and the term "supercritical" in heterogeneous catalysis refers to a dense multi-component, but single, reaction phase.

    • Such stability is consistent with both the high solubilities of organics in supercritical carbon dioxide (preventing catalyst deactivation by the adsorbed species acting as cage blocking agents), and with the stability towards leaching of sol-gel encapsulated metal "onium" ion pairs.
