.../methodology/approach Several papers have been published (1900‐1999), which aimed to investigate and explain the effect of organic compounds on the corrosion inhibition process. Two methods were used to determine the corrosion rate, weight loss and galvanostatic polarization. Additionally, the effects...

... 2008 Organic compounds Acids Inhibitors Steel Thiourea (TU) has been studied as a corrosion inhibitor by several groups of workers (Ateya et al., 1981, 1984 ; Hoar, 1948 ; Inder, 1993) and their reports were conflicting. Some workers findings on the efficiency of TU...

... of isoxazolidines were prepared. Corrosion inhibition efficiencies of these organic compounds were determined by gravimetric and electrochemical methods, using carbon steel as the substrate metal and 0.5 M H₂SO₄ at 40‐70°C as the corrosive environment. Concentration of inhibitor was varied...

...H.S. Awad; S. Abdel Gawad Purpose To investigate the capability of a series of nitrogen‐based heterocyclic organic compounds in inhibiting corrosion of iron in HCl and elucidate the dominant active form of the applied compounds during the adsorption process to explore the mechanism of their action...

...B. Ramesh Babu; K. Thangavel Purpose To study the effects of isomers of organic compounds such as phenylenediamine, toluidine and nitroaniline as inhibitors for the corrosion of carbon steel in sulfuric acid. Design/methodology/approach Standard methods have been adopted in this study...

.... Originality/value All organic compounds presented in this work are new and this is the first time their corrosion inhibition characteristics have been evaluated. Yellow HgO and m‐chloroperbenzoic acid, obtained from Fluka Chemie AG, were used as received. All solvents were of HPLC grade. Silica...

...A.S. Fouda; A. Abd El‐Aal; A.B. Kandil Purpose To show the effect of organic compounds containing O and N atoms on the corrosion inhibition of Cu in HNO₃ and; the effect of some donating substituent groups on the corrosion inhibition. Design/methodology/approach A range of published...
