摘要
以四丁基溴化铵(TBAB)为氢键接受体(HBA),壬二酸(AzA)、苯齐酸(BeA)和硼酸(BoA)为氢键供体(HBD),衍生出三种新的二元酸性深共晶溶剂(DES)。为了绘制完整的相图并找到形成 DESs 的摩尔比,我们将 HBA 和 HBD 以各种摩尔比混合在一起,并研究了它们的热行为(采用差示扫描量热法)和稳定性。应用包括 Wilson、NRTL 和常规溶液在内的活度系数模型来关联测得的固液平衡数据。傅立叶变换红外光谱和核磁共振分析用于研究化学结构、DESs 成分之间氢键的形成以及所制备 DESs 的纯度。在不同温度下测量了这些 DES 的物理化学特性,包括熔点、密度、声速、电导率和折射率。成功评估了这些新型 DES 在溶解四种金属氧化物(包括 PbO、CuO、Fe2O3 和 ZnO)方面的性能,并将所获得的溶解度值与所报道的文献数据进行了比较。
Novel acidic deep eutectic solvents: synthesis, phase diagram, thermal behavior, physicochemical properties and application
Three new binary acidic deep eutectic solvents (DESs) were derived from tetrabutylammonium bromide (TBAB) as a hydrogen bond acceptor (HBA) coupled with azelaic acid (AzA), benzilic acid (BeA) and boric acid (BoA) as hydrogen bond donors (HBD). In order to draw the complete phase diagram and find the molar ratios in which the DESs are formed, HBA and HBDs were mixed together in the full range of molar ratios and their thermal behavior (by differential scanning calorimetry method) and stability were investigated. The activity coefficient models including Wilson, NRTL and regular solution were applied to correlate the measured solid–liquid equilibrium data. FT–IR and NMR analysis were used to investigate the chemical structures, occurrence the hydrogen bond formation between the DESs constituents and purity of the prepared DESs. Physicochemical properties of these DESs including melting point, density, and speed of sound, conductivity and refractive index were measured at different temperatures. The performance of these new DESs were successfully evaluated for the dissolution of four metal oxides including PbO, CuO, Fe2O3 and ZnO and the obtained solubility values were compared with the reported literature data.
