摘要：

Present work deals with oxygen mass transfer in an oil-in-water biphasic medium, employed in the production of gamma-decalactone by the biotransformation of methyl ricinoleate. A bubble column contactor was used to carry out the absorption experiments. The influence of operating conditions (gas flow-rate and organic phase composition) upon the gas-liquid interfacial area and mass transfer coefficient has been analysed and experimental results allow describing the mechanism of oxygen transfer from gas phase into the biphasic medium.
