Abstract

Abstract : N-Butyl amine has been grafted unto Dow epoxy resin. The product was evaluated as an acid inhibitor by gravimetric techniques. The reduction in corrosion of aluminium in 1 M HCl solution was 92% at 30 ∘ C and 83% at 60 ∘ C with an inhibitor concentration of 100 ppm. The corrosion rate at this concentration was 3.0 × 10 − 2 and 1.5 × 10 − 1 mm/yr at 30 ∘ and 60 ∘ C . For the specimens in HCl without inhibitor at 10-hour immersion period, the corrosion rate was 3.8 × 10 − 1 and 8.6 × 10 − 1 mm/yr, respectively, at 30 ∘ and 60 ∘ C . Data obtained correlate with Langmuir isotherm.
