Abstract
A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner is provided wherein a dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel in such a manner that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.
Claims2
A process for producing an emulsion, comprising a step of allowing flows of a first continuous phase and a dispersion phase to join together at a first junction to form a two-phase flow and then allowing the two-phase flow, consisting of the flows of the first continuous phase and the dispersion phase joined together, to join a flow of a second continuous phase at a second junction to form an emulsion containing the dispersion phase.
A process for producing microcapsules, comprising a step of allowing flows of a first continuous phase and a dispersion phase to join together at a first junction to form microdroplets and then allowing the flow of the first continuous phase containing the microdroplets to join a flow of a second continuous phase at a second junction to form microcapsules containing the first continuous phase containing the microcapsules.
