✦ Synopsis

From experiments in a stirred cell contsctor with flat gaeliquid interface, it is shown that the rate of xnsss transfer of oxygen into an aqueous solution can he enhanced by the presence of small amount8 (0.5-l ~01%) of a dispersed organic phase (e.g. hexadecane, decane, decanol or cyclohexane), provided that the droplet diameter is in the order of or smaller than the tilm thickness (D/k=) and the solubility of oxygen in the organic phase is larger than in water. A simple model is proposed that predicts the experimentally observed enhancement factors with reasonable accuracy.
