    摘要： Compositions and methods are provided for reducing, inhibiting, or preventing corrosion of a surface, the polyamine compounds corresponding to the structure of Formula 1 or 2, or a salt thereof: wherein X1 is —C(O)R9 or —[C(R10R11)]p—C(R12)(X2)—R13; X2 is —OH or —NH2; R1 and R4 are independently hydrogen, alkyl, or —[C(R10R11)]p—C(R12)(X2)—R13; R2, R3, R5, R6, R7, R8, R10, R11, and R12 are independently hydrogen or alkyl; R9 and R13 are independently C7 to C30 alkyl or alkenyl; m and o are integers from 1 to 10; n is an integer from 1 to 6; and p is an integer from 1 to 10; wherein X2 is —OH or —NH2; R21, R22, R23, R24, R25, R26, and R28 are independently hydrogen or alkyl; R27 is C10 to C30 alkyl or alkenyl; m and o are integers from 1 to 10; n is an integer from 1 to 6; and q is an integer from 0 to 10.

    摘要： Compounds, compositions and methods are provided for reducing, inhibiting, or preventing corrosion of a surface, using a corrosion-inhibiting composition comprising a dispersant having the structure of Formula 1 and a corrosion inhibitor having the structure of Formula 2 wherein X1 is hydroxyl, —OC(O)R1; X2 is hydroxyl, or —OC(O)R2; X3 is hydroxyl or —OC(O)R3; R1, R2, and R3 are independently C10 to C30 alkyl or alkenyl; m, n, and o are independently integers from 1 to 10; R20 , R21, R22, R23, and R24 are independently hydrogen or —C(O)—R31; R31 is C10 to C30 alkyl or alkenyl; p is an integer of 0 or 1; q is an integer of 1 to 4; r is an integer of 0 or 1; s is an integer of 0 or 1; t is an integer from 1 to 4; and p1, q1, r1, r2, s1, and t1 are independently integers from 1 to 6; wherein when p, r, and s are 0, q+t is an integer from 4 to 8 and at least one of R20 , R21, R22, R23, and R24 is —C(O)—R31.
