| Abstract |
| In this work, seven surface-active agents were prepared based on ricinoleic hydrazide. The six surfactants that have a nonionic moiety were prepared by a reaction of ricinoleic hydrazide with succinic anhydride in an open-ring reaction, and then the product reacted with different molecular weights of polyethylene glycol to produce this formula (PMRH x). The letter seven surfactant has a cationic moiety, and its general formula is (RHATAS). Their chemical structure was confirmed by FT-IR, 1HNMR, and 13CNMR. The surface active and thermodynamic properties of these surfactants were calculated based on surface tension measurements at 25°C, 35°C, and 55°C. The interfacial tension for this surfactant was measured at the CMC concentration in formation water at 50°C and 70°C. The values of interfacial tension were cited between 10-1 and 10-2 mN/m. From the obtained data, the negative value of ΔGads and the data on interfacial tension were drawn into a visualization image to employ these surfactants in an application for increased oil recovery |
