ABSTRACT:
The preparation of finely-divided, homodisperse dispersions from a liquid medium having sparingly soluble particles contained therein, the particles being produced in a tubular reactor by the reaction of reactants dissolved in the medium, is carried out by introducing the solutions of the reactants, at least at the reaction temperature, into the tubular reactor separately from one another, as coaxial, laminar, parallel flows, and by shielding them from the reactor wall.
