Antikorrosive Eigenschaften von quartären Ammoniumverbindungen mit AlkylthiomethylrestDer Hemmwert von 3-Brom(n-alkylthiomethyl)pyridinium-, 3-Chlor(n-alkylthiomethyl)pyridinium-, 3,4-Dimethyl(n-alkylthiomethyl)pyridinium-, 1-Methyl-2-Methyl-3-(n-alkylthiomethyl)imidazolium-, 1-Butyl-3-(n-alkylthiomethyl)imidazolium- und (n-alkylthiomethyl)isochinoliniumchlorid bei der Korrosion von Kohlenstahl in 2 m Salzsäure, 2 m Schwefelsäure und Trinkwasser wurde gravimetrisch ermittelt. Der Hemmwert ist danach in sauren Medien höher als in Wasser. In stagnierendem saurem Medium bei 18 °C erreicht der Hemmwert ein Maximum bei 0,05 g/l Inhibitor und bei 8 h Versuchsdauer.
Notes:
The inhibition effect of chlorides: 3-bromo[(n-alkylthio)methyl]pyridinium, 3-chloro[(n-alkylthio)methyl]pyridinium, 3,4-dimethyl[(n-alkylthio)methyl]pyridinium, 1-methyl-2-methyl-3-[(n-alkylthio) methyl]imidazolium, 1-butyl-3-[(n-alkylthio)methyl]imidazolium and [(n-alkylthio)methyl]isoquinolinium on the corrosion of carbon steel in 2 M hydrochloric acid, 2 M sulphuric acid and drinking water was studied gravimetrically. The inhibitor efficiency is higher in acidic environments than in water. It appears that in stagnant acid solutions at room temperature maximum inhibiting efficiency is obtained at the inhibitor concentration of 0.05 g/l and 8 hrs' test duration.
