Spontaneous emulsification in the system water/benzene/ethanol: Phase equilibria and emulsification mechanism

Abstract: Solutions (Or), along the de-mixing line in the system water/benzene/ethanol were contacted with water (W) and the spontaneous emulsification followed by a camera at 40pictures/s. The emulsions formed predominantly in the solution layer for both the aqueous and organic branch of the de-mixing line. These results were projected on the phase diagram of the system and a direct relationship between diagram features and the mechanism of spontaneous emulsification showing a significantly more powerful reaction for solutions of a composition close to the plait point of the system.
