Abstract

The invention relates to an apparatus for contacting two immiscible liquids having at least one electrode for the application of an electric field. The electrode is coated with at least two layers of different insulating materials, the first layer which is in contact with the electrode being formed from a liquid insulating material, e.g. benzylneocaprate or transformer oil, while the outer layer is formed from a solid insulating material, e.g. polytetrafluoroethylene. These electrodes are preferably in the form of bars arranged parallel to the fluid flow direction and they are provided with deflectors to ensure that no dispersed phase flow in the form of a film takes place along the bars.
