PROCEDIMIENTO PARA LA OBTENCION DE BENZOILALANINAS INHIBIDORAS DE LA CORROSION EN SISTEMAS ACUOSOS

摘要

Benzoyl alanines having the formula: in which the symbols R1 and R2 (a) both represent hydrogen or (b) both represent a straight-chain or branched chain alkyl residue having from 1 to about 6 carbon atoms, or (c) R1 represents hydrogen and R2 represents a straight-chain or branched chain alkyl residue having from 1 to about 6 carbon atoms and in which the symbol R3 represents a C(CH3)m(CH2OH)3-m moiety wherein the symbol m represents an integer of from 0 to 3 and alkali metal and ammonium salts thereof, are disclosed. The compounds are useful as corrosion-inhibitors for metals in aqueous systems.
