New compounds have the formula I: <CHEM> wherein R is a C1-C12 straight or branched chain alkyl residue, a C2-C12 straight or branched chain alkenyl residue, a C5-C12cycloalkyl residue, a C6-C10 residue or a C7-C12 aralkyl residue; and X is a C1-C10 straight or branched alkylene residue, a C2-C10 straight or branched chain alkenylene residue or a C6-C10 arylene residue; as well as derivatives of the compounds of formula I; and enantiomers, racemic mixtures, and mixtures of diastereomers. The new compounds are useful e.g. as corrosion inhibitors in aqueous systems. |
