%X 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. 1. Introduction Corrosion is most commonly referred to as the degradation of a material due to its reaction with its environment. Such degradation may mean deterioration of the physical properties of the material which may be in form of weakening of the material due to loss of cross-sectional area, shattering due to hydrogen embrittlement, or cracking due to sunlight exposure. Corrosion is usually found in several materials but most especially in metals; these materials have both domestic and industrial uses but the existence of corrosion which can take place under acidic or alkaline medium has resulted in limitation to their use. Importance of protection against corrosion in acidic or alkaline solutions is known to be increased by the fact that metals are more susceptible to be attacked in aggressive media, most of which are the commonly exposed metals (such as mild steel) in industrial environments [1]. The corrosion process is usually slowed down in various ways one of which is the use of corrosion inhibitors which when added in small amounts to a corroding environment decreases the rate of attack by such environment on material [2¨C4]. Being the third most abundant element and the most abundant metal, aluminum has found several industrial applications which may be due to its economical considerations and the fact that its corrosion falls into general attack [5]. Thermodynamically, aluminum is expected to have a low corrosion resistance. The high corrosion resistance is due to the presence of a thin, compact film of adherent aluminum oxide on the surface which is formed on exposure to either air or water. This aluminum oxide dissolves in some chemicals, notably strong acids and alkaline solutions. When the oxide film is removed, the metal corrodes rapidly by uniform dissolution. So study of aluminum sheet corrosion phenomena has become important particularly in acidic media because of the increased industrial applications of acid solutions [6¨C9]. In the past time, use of inhibitors has been one of the most common different protective means used to control corrosion. Most inhibitors reported
