Title METHOD AND DEVICE FOR PRODUCING COMPOSITION HAVING DISPERSED PHASE FINELY DISPERSED IN CONTINUOUS PHASE meetings
Abstract

The present invention addresses the problem of providing a method for producing a composition having a dispersed phase with a low polydispersity that is finely dispersed in a continuous phase, said method providing excellent production efficiency. The problem is solved by a method for producing a composition having a dispersed phase that is finely dispersed in a continuous phase, said method including: (A) a step in which a swirling flow of a continuous phase liquid flows inside a cylindrical body having a circumferential surface, part or all of which is constituted by a porous membrane

(B1) a step in which a dispersed phase fluid is injected into the swirling flow via the porous membrane, and forms a fluid column that extends inside the cylindrical body from the surface of the porous membrane

and (B2) a step in which, when the average pore diameter of the porous membrane is regarded as P, part of the fluid column is cut by the shearing force of the swirling flow at a distance of 2P to 10P from the surface of the porous membrane in the radial direction.
