摘要：A new ultra-long chain monounsaturated 4-(N-nervonicamidopropyl-N,N-dimethylammonium)butane sulfonate(NDAS)zwitterionic surfactant with ultralow interfacial tensions was developed through the modification of nervonic acid derived from renewable non-edible seed oils by a simple and effective method.Its structure was characterized by ESI-HRMS,1 H NMR,and 13 C NMR.NDAS surfactant exhibited a strong interfacial activity(~10^(-4) mN/m)between the crude oil and the formation brine at a very low surfactant dosage(0.05 g/L)and at high salinity conditions,which is equivalent to 2%(w/w)of dosage of the most traditional surfactants used in the enhanced oil recovery field.Meanwhile,at a very low concentration(0.05 g/L),NDAS demonstrated strong NaCl compatibility up to 100 g/L,Ca^(2+)ions compatibility up to 200 mg/L,and temperature stability up to 90℃.The surface tension,emulsification,and biodegradability parameters were also evaluated.This work consolidates our hypothesis that increasing the hydrophobic chain length of a surfactant certainly contributes to the high interfacial activity and good compatibility of salts and temperatures.Hence,it will facilitate the design of a sustainable alternative to petroleum-based chemicals to develop bio-based surfactants and extend the domain of bio-based surfactants to new applications such as in enhanced oil recovery(EOR).
