1. A method for treating an emulsion of a hydrocarbon, comprising
(i) providing an emulsion of a crude hydrocarbon, wherein said emulsion contains water; (ii) adding an additive to the emulsion to obtain a treated hydrocarbon, the additive being represented by the following formula: wherein m is an integer between 0 and 10 inclusive; R1 is a branched or straight-chained C10-C800 alkyl or alkenyl group; R2 is a C1-C4 branched or straight chained alkylene group; R3 is a C1-C4 branched or straight chained alkylene group; R31 is hydrogen or —R8—R9, wherein R8 is C1-C4 branched or straight chained alkylene group, and R9 iswherein R91 is a branched or straight-chained C10-C800 alkyl or alkenyl group; or R8 and R9 together are a C1-C4 branched or straight chained alkyl group optionally substituted with one or more amine groups; and further wherein the —N(R31)—R3— repeat unit is optionally interrupted in one or more places by a nitrogen-containing heterocyclic cycloalkyl group; and
R4 and R5 are each independently selected from (a) hydrogen; (b) a bond connected to R31 in the last distal —N(R31)—R3— repeat unit; or (c) —R6—R7, wherein R6 is C1-C4 branched or straight chained alkylene group, and R7 is wherein R71 is a branched or straight-chained C10-C800 alkyl or alkenyl group; wherein z is 1 or 2, and y is an integer between 1 and 5 inclusive; and (iii) separating the water from the treated emulsion of crude hydrocarbon.
