Synthesis of eugenyl acetate by enzymatic reactions in supercritical carbon dioxide
Supercritical carbon dioxide (SC-CO 2) as reaction medium has gained attention in the
production of terpenic esters catalyzed by lipases. Therefore, this work investigated the
production of eugenyl acetate by esterification of eugenol and acetic anhydride in SC-CO 2
using two commercial lipases (Lipozyme 435 and Novozym 435) as catalysts. The influence
of enzyme concentration (1⿿ 10% weight/weight), substrates⿿ molar ratio (1: 1 to 5: 1),
temperature (40⿿ 60° C) and pressure of SC-CO 2 (10⿿ 30 MPa) on the esterification rate …
