A PROCESS FOR INTIMATELY CONTACTING NON-AQUEOUS LIQUID PHASES OF DIFFERENT POLARITY INCLUDING A HYDROCARBON OIL AND A SECOND DILECTIRC LIQUID OF POLAR CHARACTER RELATIVE TO THE HYDROCARBON WHICH COMPRISES BRINGING THE LIQUID PHASES INTO CONTACT WITHIN A DISPERSION ZONE DEFINED BY OPPOSING ELECTRODES, FORMING A FINE DISPERSION OF DROPLETS OF THE SECOND DIELECTRIC LIQUID IN THE HYDROCARBON PHASE BY SUBJECTING THE PHASES TO THE INFLUENCE OF AN INHOMOGENEOUS ELECTROSTATIC FIELD OF SUFFICIENT STRENGTH IMPOSED ACROSS THE ELECTRODES TO FORM A FINE DISPERSION OF THE LIQUID PHASES, MAINTAINING ONE ELECTRODE IN CONTACT WITH THE CONTINUOUS LIQUID PHASE OF THE SECOND DIELECTRIC LIQUID, MAINTAINING A REGION CORRESPONDING TO THE NORMAL INTERFACE OF THE NON-AQUEOUS LIQUID PHASES WITHIN THE INHOMOGENEOUS ELECTROSTATIC FIELD AND MAINTAINING THE PHASES UNDER THEINFLUENCE OF THE ELECTROSTATIC FIELD FOR SUFFICIENT TIME TO EFFECT TURBULENT SUBSTANTIALLY HOMOGENEOUS MIXING OF SAID PHASES
