Lignin derivative compounds can be applied in various industrial processes as disperser, flocculant, and <br /> <br /> <br /> <br /> surfactant in Enhanced Oil Recovery (EOR). However, the synthesis process from lignin was still less <br /> <br /> <br /> <br /> effective and efficient. In this study, the modified lignin derivatives has been synthesized from sugarcane <br /> <br /> <br /> <br /> bagasse lignin utilizing MAOS (Microwave Assisted Organic Synthesis). Lignin from sugarcane bagasse <br /> <br /> <br /> <br /> was reacted with diethylene triamine (DETA) through the Mannich reaction, followed by alkylation using <br /> <br /> <br /> <br /> 1-bromododecane. The reaction took place in a CEM DISCOVER SP® microwave reactor. The <br /> <br /> <br /> <br /> surfactant structure was analyzed using Fourier Transform InfraRed (FT-IR) and 1H-Nuclear Magnetic <br /> <br /> <br /> <br /> Resonance (1H-NMR). The compatibility tests, such as aqueous stability test, interfacial tension test, <br /> <br /> <br /> <br /> phase behaviour test with X oil using synthetic brine 10000 ppm in salinity was carried out. The aqueous <br /> <br /> <br /> <br /> stability test showed that the modified lignin could dissolve well in synthetic brine until day 30th <br /> <br /> <br /> <br /> (aminated lignin) and day 14th (aminated and alkylated lignin). The results of the modified lignin phase <br /> <br /> <br /> <br /> behavior test showed that Winsor III type microemulsion was formed at a concentration of 0.5%, 1.00%, <br /> <br /> <br /> <br /> 1.50%, 2.00%, 2.50% and 3.00%. Interfacial tension test results of aminated lignin showed that the CMC <br /> <br /> <br /> <br /> value was achieved at 2.5% of concentration with interfacial tension value 2.40 dyne/cm. Interfacial <br /> <br /> <br /> <br /> tension test results of the aminated and alkylated lignin showed that the CMC value was achieved at 2.0% <br /> <br /> <br /> <br /> with interfacial tension value 2.78 dyne/cm.
