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.
