(Main)Surface active agents - Determination of the water number of alkoxylated products
Surface active agents - Determination of the water number of alkoxylated products
This European Prestandard specifies the determination of the water number of ethoxylated products up to about 70% ethylene oxide. EO/PO block polymers with water numbers higher than about 23 become hard to interpret. NOTE: The values obtained by this method are not completely identical with the water number obtained in dioxane, in particular water numbers higher than 23.
Grenzflächenaktive Stoffe - Bestimmung der Wasserzahl von alkoxylierten Produkten
Diese Europäische Norm legt die Bestimmung der Wasserzahl von ethoxylierten Produkten mit einem Massenanteil an Ethylenoxid bis zu etwa 70 % fest. EO/PO-Blockpolymere mit Wasserzahlen größer als etwa 23 sind schwierig zu interpretiereN. ANMERKUNG: Die Werte, die mit diesem Verfahren bestimmt werden, sind jedoch nicht vollständig identisch mit der Wasserzahl, die in Dioxan erhalten wird; dies gilt besonders für Wasserzahlen größer als 23.
Agents de surface - Détermination du nombre d'eau dans les produits alkoxylés
La présente prénorme européenne prescrit une méthode de détermination du nombre d'eau des produits éthoxylés contenant jusqu'à 70 % d'oxyde d'éthylène. Les polymères d'OE/OP en blocs dont le nombre d'eau est supérieur à environ 23, posent des problèmes d'interprétation. NOTE: Les valeurs obtenues avec la présente méthode ne sont pas absolument identiques au nombre d'eau obtenu avec le dioxane, en particulier dans le cas de nombres d'eau supérieurs à 23.
