Abstract: For prepn. of a suspension from dusts (powders) a wetting out vapour is introduced into an agglomerate of particles, being isolated from the surroundings. The vapour is that of liquid which is water miscible with a b.pt. below that of a dispersing fluid used. Conversely it forms an azeotrope with the dispersing fluid. The surfaces of the particles are wetted out and the agglomerate is allowed to stand for a max. of 5 hrs. with opt. heat maintenance. Both the agglomerate and the vapours are cooled at least below the b.pt. of the wetting liq. This is followed by adding the dispersing fluid and the system is opt. heated to at least the b.pt. of the wetting liq. The system is allowed to stand for a max. of 12 hrs.. Simultaneous opt. cooling to ambient temp. also takes place. The wetting liq. is removed by ordinary or azeotropic distn. and the system is allowed to be permeated. - In some cases the wetting liq. is added directly to the aggregate and is allowed to evaporate, opt. heated to above its b.pt.)
