Abstract: 1. A process for the preparation of reaction products of alkanolamines with unsaturated fatty acids of 12 to 30 carbon atoms or fatty acid mixtures of 12 to 30 carbon atoms containing unsaturated constituents by reacting the components at elevated temperature, wherein the fatty acid component and at least one dialkanolamine of 2 or 3 carbon atoms per hydroxyalkyl radical are allowed to act on one another in a molar ratio of 1:1.0 to 1.6 at a temperature of from 110 to 140 degrees C in the absence of solvents, and the reaction is discontinued when the reaction mixture has an acid number of 45 to 75.

Abstract: Products which have been obtained by reacting an acid of the formula I I where R1 and R2 are hydrogen, fluorine, chlorine, bromine or alkyl or alkoxy of 1 to 4 carbon atoms, but the sum of the carbon atoms of R1 and R2 is not greater than 7 and preferably not greater than 3, A is a benzene, naphthalene or anthracene radical or a biphenyl structure, such as a diphenyl, diphenylmethane, diphenyl ether, diphenyl sulfide, diphenyl sulfoxide or diphenyl sulfone radical, R3 is hydrogen, alkyl of not more than 4 carbon atoms, beta -cyanoethyl or hydroxyalkyl of 2 to 4 carbon atoms, R4 is hydrogen, fluorine, chlorine, bromine, alkyl or alkoxy of 1 to 4 carbon atoms, hydroxyl or carboxyl and X is -SO2- or -CO-, with an amine of the formula II II where R5 and R6 are hydrogen, C1-C4-alkyl, C2-C4-hydroxyalkyl and/or R7 and R8 being hydrogen, C1-C4-alkyl or C2-C4-hydroxyalkyl and n being an integer from 2 to 4, in the ratio, expressed in terms of equivalents, of from 1:1 to 1:4, and corrosion inhibitors which contain these products, with or without the admixture of an alkanolamine/boric acid reaction product.
