The theoretical model of phase inversion using structural instability of population balance in agitated liquid-liquid dispersion was proposed. The model described the hysteresis of phase inversion and the effects of stirrer speed and physical properties on phase inversion. Phase inversion experiments were carried out on liquid-liquid dispersion systems composed of water and hydrocarbon mixtures. The physical properties of the organic components were varied by mixing the hydrocarbon with carbon tetrachloride. The volume fractions of dispersed phases of various densities, viscosities, and interfacial tensions were measured and agreed well with those estimated by the model. This is an abstract of an article originally published in Kagaku Kogaku Ronbunshu, 29, p. 351-356 (2003).
