Patent

CA 2472966

The invention relates to alkylglycol alkoxylates and alkyldiglycol alkoxylates that are obtainable by alkoxylating C4-8 alkylglycols or diglycols with C2-5 alkoxides up to an average alkoxylation degree of 1 to 8, based on the C4- 8alkylglycols or diglycols. The invention further relates to mixtures from C2- 5 alkoxylates of C4-8 alkylgycols or -diglycols that have an average alkoxylation degree of 1 to 8 and tensides that have an interfacial tension of less than 45 mN/m at 20 ~C when dissolved in an amount of 5 g/l of water, and/or to diyhdroxyalkins or derivatives thereof.

Alcoxylates d'alkylglycol et d'alkyldiglycol qui peuvent être obtenus par alcoxylation d'alkylglycols C¿4-8? ou d'alkyldiglycols C¿4-8? avec des alcoxydes C¿2-5? jusqu'à un degré d'alcoxylation moyen de 1 à 8, par rapport aux alkylglycols C¿4-8? ou aux alkyldiglycols C¿4-8?. La présente invention concerne en outre des mélanges d'alcoxylates C¿2-5? d'alkylglycols C¿4-8? ou d'alkyldiglycols C¿4-8?, qui présentent en moyenne un degré d'alcoxylation de 1 à 8, et de tensioactifs qui possèdent une tension interfaciale inférieure à 45 mN/m à 20 ·C lorsqu'ils sont dissous à raison de 5g/l d'eau et / ou de dihydroxyalkines ou de leur dérivés.
