1474112 Preparing dye granulates and granular detergents CIBA-GEIGY AG 15 March 1974 [16 March 1973 25 Feb 1974] 11684/74 Headings C4P and C5D [Also in Divisions A2 A5 B1 C2 and C3] Granulates of a substance, e.g. a dyestuff or a detergent, are prepared by suspending the substance in a first liquid in which it does not dissolve, adding a second liquid which at least partly dissolves the substance, the first and second liquids being either immiscible or only partially miscible, in an amount so as to form a multiphase system and subjecting the resulting system to turbulence such that agglomerates of the substance are formed (see Division B1). Granulates of dyestuff, e.g. basic, acid, sulphur, vat, mordant, chrome and disperse dyestuffs, pigments and direct dyestuffs, or granulates of a heavy duty or nonionic detergent may be prepared by the above process. |
