Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A new benzimidazoles derivatives of 8-hydroxyquinoline have been synthesized and its chemical structure was elucidated and confirmed using different spectral methods such as 1H and 13C NMR spectroscopy. The inhibitive action of 5-((…2-phenylbenzimidazol-1-yl)-methyl)-quinolin-8-ol (Q-H) against the corrosion of mild steel in 1.0 M hydrochloric acid solution were investigated at different temperatures by a series of known techniques such weight loss and electrochemical measurements. In order to improve inhibition property, the effect of substitution onbenzimidazoles derivatives of 8-hydroxyquinoline towards mild steel corrosion inhibition in hydrochloric acid medium was also studied. It was found that the studied compounds exhibit a very good performance as inhibitors for mild steel corrosion in 1.0 M hydrochloric acid (HCl). Results show that the inhibition efficiency increases with decreasing temperature and increasing concentration of inhibitor's. 96 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Steel are present with very high percentages in industrial sectors such as (technological industry, construction sectors), despite a large amount of steel is destroyed by corrosion in harsh environments especially in acidic environm…ents. Corrosion therefore affects most industries and can cost billions of dollars each year at an economical level. So, stopping or at least slowing this damage became mandatory. Quinoxalines proved to be a good corrosion inhibitor of mild steel in acid media. Therefore, keeping an eye on the industrial and environmental scenarios, the first chapter for our Book deals with the synthesis of newly 8-hydroxyquinoline derivatives namely and characterized by 1H and 13C NMR Nuclear Magnetic Resonance spectroscopy. Their inhibition performance was studied against the corrosion of mild steel in hydrochloric acid by a chemical and electrochemical techniques. It was found that the studied compounds exhibit a very good performance as inhibitors for mild steel corrosion in hydrochloric acid medium. It has been determined that the adsorption for the studied inhibitors on mild steel and also Scanning electron microscopy was performed and discussed for steel surface. 100 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this work, we have synthesized and characterized novel organic compounds. These organic compounds were characterized by UV-visible spectroscopy (UV-Vis), Elemental analysis (EA), Infrared (IR), Mass spectrometry (MS), 1H-NMR and…13C-NMR . These organic compounds were tested as corrosion inhibitors of mild steel in 1.0 M HCl by experimental and theoretical investigations. The surface of the steel before and after corrosion was characterized by the Scanning Electron Microscope coupled with Dispersive Energy Analysis (SEM-EDAX) and the gravimetric solution was analyzed by UV-visible spectrometry. 112 pp. Englisch.
