    摘要： Disclosed is the use of alkoxylated dendrimers for breaking oil/water emulsions. The alkoxylated dendrimers have a molecular weight of from 2400 to 100 000 g/mol and have been alkoxylated with C2-C4-alkylene oxide groups or a mixture of such alkylene oxide groups such that the alkoxylated dendrimer has a degree of alkoxylation of from 1 to 100 alkylene oxide units per free OH group. The alkoxylated dendrimers are added to the oil/water emulsions in amounts of from 0.0001 to 5% by weight, based on the oil content of the emulsion to be demulsified.
