A process for making and a method for using a corrosion inhibitor composition to reduce the corrosion rate of a metal by a fluid containing a corrosion agent. The corrosion inhibitor composition comprises <EMI ID=1.1 HE=81 WI=117 LX=610 LY=708 TI=CF> <PC>R1, R2, R1' may be (i) alkyl groups having 5 to 29 carbon atoms, (ii) oxygenized, sulfurized, phosphorylized alkyl groups having 5 to 29 carbon atoms, (iii) a mixture of (i) and (ii), R3 are -CO2H, -SO3H, -PO3H2, -CO2R7, -CON7H2, -CONHR7, or CON(R7)2 groups, R3' are -CO2H, - SO3H, -PO3H2, -CO2R7', -CONH2, -CONHR7', or CON(R7')2 groups, each R7 is selected from H, alkyl, alkylaryl, cycloalkyl, heteroaromatic groups having 1 to 10 carbon atoms, each R7' is selected from H, alkyl, aryl, alkylaryl, cycloalkyl, heteroaromatic groups having 1 to 10 carbon atoms, R8, R8' are H or linear alkyl groups having 1 to 10 carbon atoms, R4' is a polyalkylene polyamine, alcohol, or thiol group having from 2 to 16 carbon atoms or a mixture thereon n = 0 to about 8, p = 1 to about 5, q = 2 to about 10, r = 0 to about 10.
