Document Type and Number:
WIPO Patent Application WO/2011/032640
Kind Code:
A3
Abstract:
The invention relates to the use of alkoxylated trialkanolamine condensates for separating water from oil emulsions, said condensates being obtained by condensation of trialkanolamines, with alkaline catalysis, and subsequent alkoxylation with at least one C2 to C4 alkylene oxide, having a number-average molecular weight of between 500 and 500,000 g/mol, comprising between 2 and 250 trialkanolamine units, and an average alkoxylation degree of between 1 and 200 alkylene oxide units per free OH group, in quantities of between 0.0001 and 5 wt. %, in relation to the oil content of the emulsion to be split.
