The study of enzymatic esterification by an immobilized lipase in supercritical carbon dioxide (SCCO?) and in n-hexane, described in our previous works, was extended to continuous operation in a tubular fixed bed. The modeling of the reaction vessel operation was achieved through the use of the simp

The peptide synthesis from N-acetyl-L-tyrosine ethyl ester (Ac-Tyr-OEt) and amino acid amides was realized using o~-chymotrypsin (CT) in acetonitrile (MeCN) or acetonitrile/supercritical carbon dioxide (SCCO2) containing small amounts of water. In both solvent systems there was an optimum water cont
Myristic acid esterification has been performed by an immobilized lipase from Mucor Miehei both in n-hexane and in supercritical carbon dioxide (SCC02). The enzyme is stable in SCC02 at 15 MPa and 323 K. The reaction rate is influenced by the concentration of water and by the reaction medium composi
