Abstract
The distribution rates of acetylacetone between water and carbon tetrachloride have been determined by stirring the two phases at various speeds while maintaining a quiescent interface at a constant area. When the stirring speed of the phases is high, the distribution rates have been little affected by stirring speeds. The results have been analyzed quantitatively by considering two rate-determining steps of diffusional and interfacial controls in aqueous and organic bulk regions and in an interfacial region. The measurements have been carried out at 10, 25, 40°C, and the activation enthalpies of interfacial transfer have also been estimated.
