SURFACTAHT-OIL-WATER SYSTEMS NEAR THE AFFINITY INVERSION PART V: PROPERTIES OF EMULSIONS

Abstract

ABSTRACT The bidimensional fornulation-water/oil ratio map is used to characterize the emulsion properties and the transitions which occur when the inversion line is crossed. Conductivity, stability and viscosity data show that there exist four regions, each corresponding to a class of emulsion, So-called A+ B+ and A− C− conditions produce normal W/0 and 0/W stable emulsions, while the B− and C+ cases lead to multiple emulsions. The transitional and catastrophic inversions are found to correspond to quite different transitions.
