    摘要: The invention relates to polymers that can be obtained by: A) reacting an epoxidized ester, which is selected from one or more unsaturated fatty acids having 8 to 26 C atoms and a polyol having 2 to 6 OH groups, with a monoamine, diamine or polyamine; B) alkoxylating the polyamine obtained hereby with a C2 to C4 alkylene oxide in molar excess so that the average degree of alkoxylation per OH group ranges from 1 to 100. The polymers have a numerical average molecular weight ranging from 500 to 100,000 g/mol. The invention also relates to the use of these polymers in quantities ranging from 0.0001 to 5% by weight with regard to the oil as demulsifiers for oil-in-water emulsions.

    摘要: The present invention relates to the use of alkoxylated polyglycerols preparable by polycondensation of glycerol and subsequent alkoxylation for demulsifying water-oil emulsions, in particular in the production of crude oil from crude oil/water emulsions. The invention provides for the use of alkoxylated polyglycerols with a molecular weight of from 250 to 100,000 units which comprise 2 to 100 glycerol units whose free OH groups are alkoxylated with C2–C4-alkylene oxide groups or a mixture of such alkylene oxide groups so that the alkoxylated polyglycerol has a degree of alkoxylation of from 1 to 100 alkylene oxide units per free OH group. The alkoxylated polyglycerols of the present invention are employed for demulsifying oil/water emulsions in amounts of from 0.0001 to 5% by weight, based on the oil content of the emulsion to be demulsified.
