Abstract
(DE)
Gegenstand der Erfindung sind Harze, erhältlich aus Verbindungen der Formel (1), in denen die Substituenten R1 und OH zueinander in ortho-, meta- oder para-Stellung stehen können, und R1 für C1-C30-Alkyl, C2-C30-Alkenyl, C6-C18-Aryl oder C7C30-Alkylaryl steht, durch die in beliebiger Reihenfolge ausführbaren Schritte A) Umsetzung mit Glyoxal und B) Alkoxylierung mit einem C2-C4-Alkylenoid im molaren Überschuss, so dass das entstehende Alkoxylat einen Alkoxylierungsgrad von 1 bis 100 Alkylenoxideinheiten pro OH-Gruppe aufweist, un die ein Molekulargewicht von 250 bis 100.000 Einheiten aufweisen, sowie deren Verwendung als Spalter für Öl/Wasser-emulsionen, insbesondere in der Erdölförderung.
(EN)
The invention relates to resins that can be obtained from compounds of formula (1), in which substituents R1 and OH can, with regard to one another, be located in ortho position, meta position or para position, and R1 represents C1-C30 alkyl, C2-C30 alkenyl, C6-C18 aryl or C7-30 alkyl aryl. The inventive resins are produced using the following steps, which can be carried out in any order: A) reacting with glyoxal; and B) alkoxylating with a C2-C4 alkylene oxide in molar excess so that the resulting alkoxylate has a degree of alkoxylation of 1 to 100 alkylene oxide units per OH group. In addition, the inventive resins have a molecular weight ranging from 250 to 100,000 units. The invention also relates to the use of these resins as demulsifiers for oil-in-water emulsions, in particular, in the domain of petroleum extraction.

L'invention concerne des résines qui peuvent être obtenues à partir de composés de formule (1), dans laquelle les substituants R1 et OH peuvent être situés l'un par rapport à l'autre en position ortho, méta ou para et dans laquelle R1 représente un groupe alkyle C1-C30, alcényle C2-C30, aryle C6-C18 ou alkylaryle C7-C30, par la mise en oeuvre, dans n'importe quel ordre, des étapes suivantes : A) mise en réaction avec du glyoxal et B) alcoxylation avec un oxyde d'alkylène C2-C4 en excès molaire de sorte que l'alcoxylat obtenu présente un degré d'alcoxylation compris entre 1 et 100 unités d'oxyde d'alkylène par groupe OH, les résines présentant un poids moléculaire compris entre 250 et 100 000 unités. L'invention a également pour objet l'utilisation de ces résines en tant que désémulsifiants pour des émulsions huile/eau, notamment dans le domaine de l'extraction de pétrole.
