The present communication reports the recent results and some general observations on parameters which enhance the reactivity and the enantiomeric eccess in lipase catalysed reactions in supercritical carbon dioxide. We examined, in particular, the lipase-catalysed synthesis of esters from secondary alcohols and acetic anhydride, as a function of pressure, temperature, substrates concentration and we compared the performance of the enzyme with the corresponding reactions in aliphatic and aromatic solvents.
