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 and 83% at with an inhibitor concentration of 100 ppm. The corrosion rate at this concentration was and mm/yr at and . For the specimens in HCl without inhibitor at 10-hour immersion period, the corrosion rate was and mm/yr, respectively, at and . Data obtained correlate with Langmuir isotherm.
