[Esterification of octanoic acid with 1-octanol catalyzed by lipase in W/O microemulsions and in microemulsion-based organogels].
The esterification reactions of octanoic acid with 1-octanol catalyzed by Candida lypolytical (CL) lipase was studied in water-in-oil microemulsions formed by water/bis-(2-ethylhexyl)sulfosuccinate sodium (AOT)/isooctane. The results of kinetic study showed that the reaction follows a Ping-Pong Bi-Bi mechanism. The values of apparent kinetic parameters were determined. Lipase has also been immobilized in gelatin-containing AOT microemulsion-based organogels (MBGs) for retention of catalytic activity. These lipase-containing MBGs proved to be a solid-phase catalysts for use in apolar organic solvents, retaining its higher activity after many runs of esterification reactions.
