松香基聚氧乙烯醚非离子型双子表面活性剂的合成与应用
Synthesis and Application of Rosin-Based Polyoxyethylene Ether Non-Ionic Gemini Surfactant
摘要
Abstract
In this research,novel rosin-based non-ionic Gemini surfactants(RNGSs)were synthesized from rosin derivatives,dehydroabietic acid(DAA)and dehydroabietylamine(DHAA),via addition and alkylation reactions.The structures of the synthesized surfactants were characterized by Fourier transform infrared(FTIR)spectroscopy and proton nuclear magnetic resonance(1 H NMR)spectroscopy.The surface activity,aggregation property,and foaming property of RNGSs in aqueous solution were investigated by surface tension measurement and dynamic light scattering(DLS).Furthermore,the cloud point was investigated to evaluate the upper temperature limit for practical application of the surfactants.To evaluate the potential of RNGSs for enhanced oil recovery(EOR),their interfacial tension(IFT),static adsorption capacity,salt tolerance,and emulsion stability were examined.The lowest critical micelle concentration(CMC)of RNGSs was 8.51×10-6 mol/L,lower than that of the commonly used non-ionic surfactant OP-10(1.29×10-4 mol/L).The cloud point of RNGSs reached 72.6℃.Furthermore,the tolerance to NaCl and CaCl2 was determined to be 300 and 10 g/L,respectively.The findings indicate that the synthesized surfactants possess the potential for application in EOR.关键词
