متن کاملcorrosion inhibition effect of ester containing cationic gemini surfactants on low carbon steel
α, ω-alkane-bis(n-myristoyloxyethyl-n, n-dimethyl)-diammonium bromide were synthesized and confirmed by ft-ir, ft-raman and 1h-nmr spectroscopy. surface tensions were measured by sigma 70 and conductivity meter ec-470c. critical micelle concentration values were 2.70×10-4∼3.05×10-4 mol/l. the krafft points were measured at 39.1 ~ 43.2℃. their inhibition effects on the corrosion of low carbon st...
متن کاملElectrochemical assessment of imidazole derivatives as corrosion inhibitors for mild steel in 3.5 NaCl solution
The corrosion inhibition efficiency of benzimidazole, 2-methylbenzimidazole and 2- aminobenzimidazole for mild steel immersed in 3.5 NaCl solution was investigated by electrochemical impedance spectroscopy EIS at concentration range from 10-5 to 10-2 M of imidazoles and temperature range from 30 to 50°C. In addition, DC polarization was examined to determine inhibition mechanism at concentratio...

15 صفحه اولSynthesis and Properties of Dissymmetric Gemini Surfactants
A series of novel dissymmetric gemini cationics surfactants was synthesized by three-step reactions. The dissymmetric gemini surfactants contain a dodecanoic acid dimethylethylamine ester as the constant cationic part on one side of the hydroxypropyl center and a similar other cationic part, but with a different acid length (from octanoic to palmitic), on the other side. The critical micelle co...
