Synthesis of Disodium Salt of Sulfosuccinate Monoester from the Seed Oil of Terminalia catappa and Its Inhibitive Effect on the Corrosion of Aluminum Sheet in 1 M HCl

Abstract

Oil was extracted from the seed of Terminalia catappa and used to synthesize disodium salt of sulfosuccinate monoester using simple reaction mechanism. The disodium salt of sulfosuccinate monoester was applied as corrosion inhibitor of aluminum sheet in 1 M HCl via weight loss method. The adsorption was found to obey Langmuir isotherm. The results presented disodium salt of sulfosuccinate monoester as an efficient inhibitor of aluminum sheet corrosion in 1 M HCl.
