Patent number: 6074441Abstract: The process for producing crystallisation products with an average particle diameter of <1 .mu.m is based on the atomisation of a solution and the simultaneous evaporation of the solvent. The atomised solution A crystallises in a gas atmosphere, in which it is simultaneously contacted with a cloud of drops 4 of a surfactant-containing liquid B, thus forming an aerosol mixture A, B which is then deposited in the form of a colloidal crystal suspension in which the surfactant-containing liquid B forms the continuous phase. The cloud of drops 4 of the surfactant-containing liquid can also be produced by atomisation.Type: GrantFiled: April 28, 1997Date of Patent: June 13, 2000Assignee: Bayer AktiengesellschaftInventors: Barbara Schulte, Stefan Hofmann, Andre Fellholter, Heiko Herold, Frank Behrendt
