Disclosed are oleyl propylenediamine-based compounds used in compositions and methods for inhibiting corrosion. The method comprises introducing into a fluid source a composition comprising one or more oleyl propylenediamine-based compounds comprising Formula I: wherein Y1, Y2, and Y3 independently are hydrogen or a substituent of Formula (II): wherein V is -O- or -NH-, W is optionally present and is a linear or branched C1-10 aliphatic group, X is -H, -NZ3 +, -COOH, -SO3H, -OSO3H2, -PO3H, -OPO3H2, or a salt thereof, each Z independently is hydrogen or a linear or branched C1-20 aliphatic group optionally interrupted or substituted with one or more oxygen atoms, and R is hydrogen or methyl, provided that at least one of Y1, Y2, or Y3 is a substituent of Formula (II). |
