摘要： A method and an apparatus for producing a dispersion, which enable high-speed and highly-efficient production of a dispersion of a reaction product having desired properties, are provided. The present invention relates to such a method and an apparatus for producing a dispersion. In the method and the apparatus, a first substance is dissolved or dispersed in a first liquid, a second substance is dissolved or dispersed in a second liquid or a low dielectric liquid, a phase of the second liquid and a phase of the low dielectric liquid are one on top of the other in such a manner that the two phases are separated from each other, a spray port of a nozzle is disposed in the low dielectric liquid phase, or is disposed at a position apart from the two phases but close to the low dielectric liquid phase in such a manner that the spray port is oriented to a liquid surface of the low dielectric liquid phase, and an electrode is disposed in the second liquid phase. In these states, droplets of the first liquid in which the first substance is dissolved or dispersed, are charged by generating a potential difference between the nozzle and the electrode, and are electrostatically sprayed from the spray port of the nozzle. In the method and the apparatus, the first liquid which was electrostatically sprayed, passes through the phase of the low dielectric liquid and reaches the phase of the second liquid so that the reaction product is dispersed in the second liquid phase or in the low dielectric liquid phase.
