Abstract
Corrosion is a costly problem all over the world. Current approaches to controlling corrosion have some paucity of efficiency, which triggers the search for novel materials that are green and cheap and made from renewable resources. In this study, an attempt was made to prepare an Acacia auriculiformis-seed-oil (ASO)-based fatty amide through a simple reaction route involving aminolysis of ASO fatty acid and diethylenetriamine. Fourier transform infrared spectroscopy and hydrogen-1 (1H) nuclear magnetic resonance were used to determine the structural characteristics of the synthesised amide. Properties such as acid value, amine value, refractive index and specific gravity were measured. The coating films were prepared by using a standard formulation, in which the synthesised fatty amide was added in different proportions. The performance of the cured films was evaluated and compared. The hydrophobicity test revealed that the hydrophobicity of film increases with the addition of fatty amide up to 2% and then decreases. The effect of the synthesised product on mild steel was investigated according to the standard protocol. The results revealed that developed fatty amide inhibited the corrosion of carbon steel up to a certain concentration (2%) in the film.
