“…These are expansively used as fabric softeners, corrosion inhibitors, dispersing agents and antistatic agents. In addition to that, desirable storage stability, viscosity, better dispersability and fabric conditioning ability make them useful in laundry applications as well as in other various industrial applications [2].…”

Imidazolinium surfactants belong to the category of cationic surfactants that have already gained the great interest of researchers due to their varied range of commercial applications. With the advancement in the field of surfactants research, imidazolinium surfactants are being converted into their corresponding gemini surfactants. Gemini surfactants are known to have exceptional selfassembling characteristics and exclusive interfacial activity that include much lower CMC and better ability to reduce surface tension than their conventional monomeric counterparts. Long reaction time associated with conventional thermal synthetic procedures and high production costs are the two major issues involved in the synthesis of gemini surfactants. The present research work involves the microwave synthesis of novel gemini imidazolinium surfactants with carbonate linkage. In order to synthesize cost effective gemini surfactants, waste cooking oils have been used as raw materials. Structural characterization of synthesized gemini surfactants has been achieved through 1 H-NMR, 13 C-NMR and FT-IR.

Corrosion inhibitors can behave as cathodic inhibitors when they mainly suppress the cathodic reaction. Conversely, they can also be anodic inhibitors when they mainly suppress the anodic reaction. When corrosion inhibitors interact with both cathodic and anodic reactions, they may behave as mixed inhibitors. This paper documents the electrochemical characterization of a phosphate ester based inhibitor which created protection from oxygen corrosion. Potentiodynamic polarization was used to determine the inhibitor behavior during the anodic and cathodic processes of corrosion. A system comprising a carbon steel electrode in 3.5% NaCl and a gas phase composed of 3% O 2 in 97% CO 2 with and without an inhibitor has been defined and tested. The oxygen corrosion mechanism on carbon steel was established through the comparison of the cathodic and anodic currents in the presence of 3% O 2 in 97% CO 2 and 100% CO 2 . The probable mechanism of inhibition by imidazoline and phosphate esters as well as the role of a sulfiding agent was explored. In the presence of oxygen, the anodic more than the cathodic inhibition performance was more related to the overall corrosion inhibition. As expected, phosphate ester based inhibitors demonstrated to be superior to imidazoline base inhibitors to abate oxygen corrosion. These results were confirmed with open-circuit (autoclave) corrosion experiments.
