Abstract: The present invention relates to N-alkyl-N'-poly(oxyalkyl)hexahydropyrimidines of the formula I in which R is C1-C30-alkyl or C2-C30-alkenyl, R is hydrogen or C1-C3-alkyl, A denotes 1,2-alkylene groups having 2 to 10, preferably 2 to 5, C-atoms, and p represents a number from 1 to 50. The invention furthermore relates to the use of N-alkyl-N'-poly(oxyalyl)hexahydropyrimidines of the formula I as corrosion inhibitors in water/oil emulsions as they are found in mineral oil.
