Abstract
The invention relates to the use of alkoxylated cyclic diamines, the reactive groups of which are alkoxylated by means of at least one C2 to C4 alkylene oxide, and the average degree of alkoxylation of which is between 1 and 200 alkylene oxide units per reactive group, in amounts of 0.0001 to 5 wt % relative to the oil content of the emulsion to be broken, to break water-in-oil emulsions.
Claims17
The use of alkoxylated cyclic diamines whose reactive groups are alkoxylated with at least one C2 to C4 alkylene oxide and whose average degree of alkoxylation is between 1 and 200 alkylene oxide units per reactive group, in amounts of 0.0001% to 5% by weight, based on the oil content of the emulsion to be broken, for breaking water-in-oil emulsions.
An alkoxylated cyclic diamine whose reactive groups are alkoxylated with at least one C2 to C4 alkylene oxide and whose average degree of alkoxylation is between 3 and 100 alkylene oxide units per reactive group and which has a number average molecular weight of 1000 to 100 000 g/mol.
A process for breaking a water-in-oil emulsion by adding to the emulsion from 0.0001% to 5% by weight, based on the weight of the emulsion, of at least one alkoxylated cyclic diamine which has a number average molecular weight of 1000 to 100 000 g/mol, the reactive groups of which are alkoxylated with at least one C2 to C4 alkylene oxide, so that the average degree of alkoxylation is 3 to 100 alkoxy units per reactive group.
