摘要: 以腰果酚环氧化物与CO2反应合成了新型腰果酚环碳酸酯及3种含氨基甲酸酯链段的季铵盐衍生物,并采用IR、1H NMR及13C NMR等方法表征了腰果酚环碳酸酯及其季铵盐衍生物的化学结构。研究了此类季铵盐衍生物的表面张力、乳化力、泡沫性能等,测定了产物的临界胶束浓度(CMC)及其饱和吸附量(Γmax)、最小分子截面积(Amin)。实验结果表明,3种季铵盐衍生物水溶液的临界胶束浓度分别为8.55、6.97、11.93 mg/L,相应临界胶束浓度下的表面张力分别为26.67、25.32、38.92 mN/m,Γmax分别为0.384、0.345、0.217 mol/m2, Amin分别为4.3×10-6、4.81×10-6、7.65×10-6 nm2。产物乳化性能、起泡能力较强,泡沫稳定性好。

Abstract: Three carbamate group-containing quaternary ammonium salt derivatives were synthesized from the novel biomass cardanol-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.
