Abstract
Germicidal complexes of poly-N-vinylpyrrolidone (PVP) with iodine are prepared in the form of granules of virtually uniform composition and particle size. To this end, the following are required: a) a solution and/or colloidal suspension of elemental iodine and of a water-soluble substance which supplies iodide ions, in a first solvent or solvent mixture and b) a solution and/or colloidal solution and/or suspension of PVP in a second solvent or solvent mixture which has different surface tension from the first solvent or solvent mixture. The PVP is at least partially soluble or wettable in the second solvent or solvent mixture. The substances dissolved or suspended in the first solvent or solvent mixture are insoluble or only sparingly soluble in the second solvent or solvent mixture. Component a) is added to component b) in small portions and with uniform mixing. A mixed phase system forms. After further mixing of the multiphase mixture, the iodine/PVP complex-containing agglomerates formed are separated off and dried. By means of the process, which can be carried out continuously, yields of iodophore granules of 75 to 100% can be achieved.
