<p>A corrosion-inhibiting composition comprising the reaction product of a benzotriazole of formula (I), a compound of formula (II) and at least one alkylene oxide, the composition optionally including halide ions. Formulae (I) and (II), wherein R1 is the same or different and is selected from the group consisting of hydrogen, halogen, C1 to C6 alkyl, C1 to C6 haloalkyl, C2 to C6 alkenyl, C2 to C6 alkynyl, C1 to C6 alkoxy, C1 to C6 alkylthio, aryloxy, arylthio, substituted C1 to C6 alkyl wherein the alkyl group is substituted with a substituted or unsubstituted phenyl, C1 to C6 alkoxycarbonyl, amino, C1 to C6 alkylamino, di(C1 to C6) alkylamino or -NHQ, wherein Q is selected from substituted or unsubstituted phenyl, nitro, cyano and thiocyanato; and n has a value of from 1 to 3; R2 is selected from straight or branched-chain alkyl, alkenyl or alkynyl having an average of from 8 to 24 carbon atoms per chain optionally substituted with substituted or unsubstituted phenyl; R3 is the same or different and is selected from the group consisting of hydrogen and C1 to C6 alkyl; x and y are integers being the same or different, the sum of x + y being from 0 to 30.</p> |
