Synthesis and Surface Active Properties of Cardanol-based Cyclic Carbonate and Its Quaternary Ammonium Salt Derivatives
摘要
Abstract
Three carbamate group-containing quaternary ammonium salt derivatives were synthesized from the novel biomass car-danol-based cyclic carbonate (C-CC) which was prepared by reaction of carbon dioxide with cardanol-based epoxides (C-E). The chemical structures of the novel cardanol-based cyclic carbonate, cardanol-based carbamate ( C-Ca) and its quaternary ammonium salt derivatives (C-QAS) were characterized by FT-IR, 1H NMR and 13C NMR. Surface tension, emulsifying ability and the foaming power of the quaternary ammonium salt derivatives were investigated. The critical micelle concentration (CMC) , the surface excess concentration (Γmax) and the minimum surface area at the interface occupied by each molecule (Amin) were determined. The results showed that the critical micelle concentrations (CMC) of the three quaternary ammonium salt derivatives 'aqueous solutions were 8.55, 6.97 and 11.93 mg/L, respectively; the surface tensions of the three aqueous solutions at CMC were 26.67,25.32 and 38.92 mN/m, respectively; the Γmax of the three C-QAS were 0.384, 0.345 and 0. 217 mol/m2, respectively; the Amin of the three C-QAS were 4. 3 × 10-6 , 4. 81 × 10-6 and 7. 65 × 10-6 nm2, respectively; and the products with strong emulsifying ability, foaming ability and superior foaming stability.关键词
