Abstract

In the process for the continuous dispersion of at least one fluid A constituting the disperse phase and at least one continuous phase constituting the enclosing phase of a fluid B, at least one fluid stream A and at least one fluid stream B are fed into a dispersion apparatus and come into contact therein in a dispersion chamber. To this end, a microstructure dispersion apparatus (1a, 1b, 3a, 3b) is used in which the fluid streams A, B are broken up into spatially separate, flowing fluid filaments by a system of microchannels (1a, 1b) associated therewith, which filaments are discharged into the dispersion chamber (4) at identical flow velocities for the particular fluid in such a manner that on discharge into the dispersion chamber (4) a fluid jet (6a) of the disperse phase is in each case immediately adjacent to a fluid jet (6b) of the continuous phase and in each case a fluid jet (6a) of the disperse phase is enclosed as it is broken up into particles in the adjacent fluid jets (6b) of the continuous phase.
