liquid (EHANP-IL). Following the synthesis, the chemical structure was confirmed by Fourier-transform infrared spectroscopy (FTIR), and proton nuclear magnetic resonance (1H NMR). The surface activity and dynamic light scattering (DLS) properties were also investigated. Further, the demulsification efficiencies of synthesized IL and EHANP was evaluated and found that the EHANP-IL was able to demulsify water-in-oil
基于聚对苯二甲酸乙二醇酯(PET)废料的糖酵解产物,制备了一种新型的两亲性离子液体(IL)。由PET的糖酵解产生的对苯二甲酸二(2-羟乙基)对苯二甲酸酯(BHET)被转化为对苯二甲酸二(2-氯乙基)对苯二甲酸酯(BCET)。缩水甘油基4-壬基苯基醚(GNE)与乙醇胺(EA)反应形成相应的胺1-((2-羟乙基)氨基)-3-(4-壬基苯氧基)丙-2-醇(HANP)然后将形成的胺用四甘醇(TEG)乙氧基化以形成乙氧基化胺(EHANP)。通过BCET将EHANP季铵化以形成相应的离子液体(EHANP-IL)。合成后,通过傅里叶变换红外光谱(FTIR)和质子核磁共振证实了化学结构(11 H NMR)。还研究了表面活性和动态光散射(DLS)特性。此外,评价了合成的IL和EHANP的破乳效率,并且发现EHANP-IL能够比各自的EHANP高效破乳油包水(W / O)乳液。
