Abstract (en)
A corrosion inhibitor (I) contains an N-alkylamide of lactobionic acid (II) and/or an alkylamine amide of lactobionic acid (III) and/or an alkyldiamide of di-lactobionic acid (IV) whereby the amide functionality in (II), (III), and (IV) contains an unsaturated alkyl chain of at least 18C atoms (for (II)) or 8-30C atoms (for (III) and (IV)). Also claimed is a metal treatment process by use of (I).
Abstract (de)
Die Erfindung betrifft Korrosionsschutzmittel oder korrosionsinhibierenden Mittel, die Lactobionsäure-N-alkylamide, deren über die Amidfunktion gebundene gesättigte oder ungesättigte Alkylgruppe eine Kettenlänge von mehr als 18 Kohlenstoffatome aufweisen, und/oder Lactobionsäurealkylaminamide und/oder Di-Lactobionsäurealkyldiamide enthalten. Weiterhin wird die Verwendung dieser Amide in Korrosionsschutzmitteln, in korrosionsinhibierenden Mitteln sowie Metallbearbeitungsmitteln beschrieben.
