preparation and evaluation of some corrosion inhibitors based on cationic surfactant for protecting oil production equipment

In the present investigation a series of quaternary iminium salts where prepared with alkyl chain length of C12, 16 and 18. The structure of synthesized products was confirmed using FTIR, mass spectra and 1H-NMR.The prepared cationic surfactants were evaluated by studying their surface properties particularly surface and interfacial tensions, the critical micelle concentration (CMC) values were determined using, surface tension method. These values indicate that
