Phase inversion in the mixing of immiscible liquids

Data are reported on phase inversion in concentrated oil‐water mixtures dispersed in a fully‐baffled stirred tank. The results indicate that water continuous dispersions in which the water concentration is as small as 40% by volume can be formed. For a vertically centered impeller the concentration of the organic liquid required for phase inversion varies inversely with the rate of energy input. The effect of impeller position is also discussed.
