Abstract (en)
[origin: WO9959958A1] Compounds of formula (I), wherein R is the alpha -side chain of an amino acid, R1 is a straight or branched chain alkyl or alkenyl residue containing 1 to 30 carbon atoms or a cycloalkyl or aryl residue having from 5 to 12 carbon atoms; R2 is hydrogen or aryl or a straight chain alkyl or alkenyl residue having from 1 to 30 carbon atoms or together with R is the alpha -side chain of an amino acid; X is a linking moiety and Y is a suitable backbone moiety on which to append the N-acylated amino acid moieties via X linkages; and n is a number between 1 and the total number of available reactive substituents on Y; are corrosion inhibitors and/or scale inhibitors.
