Alkanolamine salts of amide acids having the formula: ##STR1## in which the circle represents a single nucleous aromatic ring or a monocyclic or bicyclic aliphatic ring system in each case with 5 or 6 carbon atoms per ring in which R.sup.1 represents an isoalkyl radical with the longest chain of 6 to 8 carbon atoms and a total of 8 to 12 carbon atoms; R.sup.2 represents a radical alkylene-X wherein the alkylene chain is a branched or straight chain and contains 1 to 4 carbon atoms; X represents OR.sup.3, O(C.sub.2 H.sub.4 O).sub.n -R.sup.3, O(C.sub.3 H.sub.6 O).sub.n -R.sup.3, NR.sup.3 R.sup.3, CN, CONH.sub.2, and COOR.sup.3 ; R.sup.3 represents hydrogen or C.sub.1 to C.sub.4 alkyl; n is an integer of 1 to 4; and wherein the carboxyl and carbonamide groups in said formula are bonded to non-olefinic carbon atoms and arranged in adjacent positions. The use of these salts as corrosion inhibitors in aqueous systems is also disclosed.
