PROCESS FOR PRODUCING PVP-H2O2 PRODUCTS
A process for the production of PVP-H2O2 products in the form of free-flowing powders, or a free-standing, porous solid or foam, is described. To prepare free-flowing powders, a fluidized bed is maintained at a reaction temperature of about room temperature to 60 DEG C and is contacted with finely d...

| description | A process for the production of PVP-H2O2 products in the form of free-flowing powders, or a free-standing, porous solid or foam, is described. To prepare free-flowing powders, a fluidized bed is maintained at a reaction temperature of about room temperature to 60 DEG C and is contacted with finely divided droplets of a 30 to 85 % by weigth aqueous H2O2 solution. Preferably the fluidized bed temperature is about 35 DEG -45 DEG C, a 5-70 % H2O2 solution is used, and the feed rate of introduction of the H2O2 solution is about 5-50 g/minute/kg PVP present. The PVP-H2O2 product preferably contains about 15-24 %, preferably 18-22 %, H2O2 (1:1 molar ratio) and less than about 5 % water.
Procédé de production de produits en PVP-H2O2 sous forme de poudres coulantes ou d'un solide ou une mousse poreux et libre. Pour préparer des poudres coulantes, on maintient un lit fluidisé à une température réactionnelle comprise entre à peu près la température ambiante et 60 °C, puis on le met en contact avec des gouttelettes finement divisées d'une solution aqueuse de H2O2 de 30 à 85 % en poids. De préférence, la température du lit fluidisé est comprise entre environ 35 et 45 °C, on utilise une solution de H2O2 de 5 à 70 %, et l'on introduit la solution de H2O2 à une vitesse d'environ 5 à 50 grammes par minute par kilogramme de PVP. De préférence, le produit en PVP-H2O2 contient environ de 15 à 24 %, et de préférence de 18 à 22 %, de H2O2 (rapport molaire 1:1) et une quantité d'eau inférieure à environ 5 %. |
