Title (DE) VERFAHREN ZUM KONTINUIERLICHEN BLEICHEN VON FLÜSSIGKEITEN MIT OZON
(EN) PROCESS FOR CONTINUOUSLY BLEACHING LIQUIDS WITH OZONE
(FR) PROCEDE POUR BLANCHIR EN CONTINU DES LIQUIDES AVEC DE L'OZONE
Abstract:
(DE) Das Verfahren zum kontinuierlichen Bleichen viskoser Flüssigkeiten besteht im wesentlichen darin, daß die Flüssigkeit als Dünnfilm mit gasförmigem Ozon in Kontakt gebracht wird. Das Verfahren ist insbesondere zum Bleichen von Alkylglykosiden geeignet.
(EN) In a process for continuously bleaching viscous liquids, a thin film of the liquid is brought into contact with gaseous ozone. The process is particularly suitable for bleaching alkylglycosides.
(FR) Dans un procédé pour blanchir en continu des liquides visqueux, un film mince du liquide est mis en contact avec de l'ozone gazeux. Ce procédé convient notamment pour blanchir des alkylglycosides.
