Zusammenfassung:Dry liquids, processes and apparatus for their preparation Dry liquids containing a hydrophobic, pyrogenically prepared silica having an individual drop size of less than 5 [mu]m are prepared by mixing the liquid and the hydrophobic silica by means of a high-intensity stirrer, a wall-channelling stirrer being moved simultaneously and the high-intensity stirrer being moved in its axial direction.
