Sulfonated alkyl ester is one of sulfonate-based surfactants that can be applied in the enhanced oil recovery (EOR) <br /> <br /> processes. However, in certain types of oil, the sulfonated alkyl ester has not shown its optimum performance yet, <br /> <br /> therefore the addition of other compounds is needed, such as the addition of co-surfactants. In this study, 2-((2- <br /> <br /> (dodecylamino)ethyl)amino)ethanol t has been successfully synthesized from the reaction between 1- <br /> <br /> bromododecane with 2-((2-(amino)ethyl)amino)ethanol by utilizing MAOS (Microwave Assisted Organic Synthesis) <br /> <br /> method to be used as co-surfactan. The structure of 2-((2-(dodecylamino)ethyl)amino)ethanol has been <br /> <br /> characterized using FTIR and NMR. A typical FTIR spectrum of the 2-((2-(dodecylamino)ethyl)amino)ethanol <br /> <br /> surfactant featured bands at wavenumbers of 3277.06 cm-1 (O–H, alcohol and N-H, amine), 1462.04 cm-1 (C-O), <br /> <br /> and 1128.36 cm-1 (C-N). The 1H NMR spectrum showed the chemical shift values for a singlet proton signal at 3.65 <br /> <br /> ppm, which indicates the proton of -OH functional group; while the proton of amine groups are showed at 2.90 <br /> <br /> ppm. The 13C NMR spectrum showed 16 high intensity signals corresponded to 16 carbon atoms in the synthesized <br /> <br /> compound. A carbon signal that appeared in 60.90 ppm indicates the carbon atom next to -OH group. The <br /> <br /> compatibility tests of the formulated surfactant, 2-((2-(amino)ethyl)amino)ethanol and sulfonated alkyl ester, have <br /> <br /> been carried out, Which consisted of the solution stability tests, interfacial tension tests, and phase behavior tests. <br /> <br /> The compatibility test results showed an optimum condition of 2-((2-(amino)ethyl)amino)ethanol solution at <br /> <br /> concentration of 1.00 %wt which resulted an IFT value of 1.58.10-2 dyne/cm. The optimum concentration of the <br /> <br /> formulated solution between 2-((2-(amino)ethyl)amino)ethanol and the sulfonated alkyl ester is at concentration <br /> <br /> of 1.00 %wt which produced the interfacial tension of 9.05 x 10-3 dyne/cm. These results indicated that 2-((2- <br /> <br /> (dodecylamino)ethyl)amino)ethanol can be used as a co-surfactant to be combined with sulfonated alkyl ester and <br /> <br /> has the capability to improve the performance of sulfonated alkyl ester surfactant in the enhanced oil recovery <br /> <br /> application.
