Two series of diquaternary cationic surfactants designated as E9Nm and E11Nm having two different alkyl chains in their chemical structure were synthesized. The chemical structures of these surfactants were confirmed using elemental analysis, FTIR and 1H‐NMR spectra. The surface activities of the different surfactants were determined using surface and interfacial tension at 25 °C. The surface parameters including: critical micelle concentration, effectiveness, efficiency, maximum surface excess and minimum surface area were determined. The surface activities of the cationic surfactants were correlated with their chemical structure. The surface activities of the surfactants increased with increasing the hydrophobic chain length. The adsorption and micellization tendencies of the surfactants in solution were determined using the free energies of adsorption and micellization. The synthesized surfactants were evaluated as biocides against bacteria and fungi. Biocidal activity data showed that a gradual increase in the hydrophobic chain length of the surfactant molecules gradually increases the efficiency of these surfactants as biocides. 相似文献

Four nonionic surfactants were prepared from the reaction of propylene oxide with oleic acid, linoleic acid, and the free fatty acid mixture from hydrolysis of jatropha oil. The chemical structures of the prepared surfactants were confirmed using IR and NMR spectroscopy. The surface activities of the prepared surfactants were dependent on the polypropylene oxide chain length and also on the nature of the alkyl chains. The nonionic surfactants were evaluated at different concentrations as corrosion inhibitors against the corrosion of Al 6061 aluminum in 2 M HCl solution. The corrosion inhibition tendencies of the surfactants were completely dependent on the fatty acid ratio in the jatropha oil and also on the polypropylene oxide chain length. The corrosion inhibition efficiencies of the surfactants were correlated to their chemical structure and their surface activities. 相似文献
