  质子吗啉基离子液体表面性质的实​​验研究

  摘要：

  在这项工作中，合成了十种具有烷基羧酸根阴离子的新型质子吗啉基离子液体（ILs），其密度和表面张力的测量范围为298.15至348.15K。该设备有助于在水含量极低且没有水蒸气的情况下在液/气界面进行测量。在相同条件下也测量了弯液面接触角。每个IL的表面张力表现出与温度的高度线性相关性，从而可以准确评估表面热力学函数（表面熵和表面能）。根据表面张力值，通过古根希姆（Guggenhiem）和Eötvös方程估算临界点。表面张力，

  New protic ionic liquids (PILs) based on the morpholinium, N-methylmorpholinium, and N-ethyl morpholinium cations have been synthesized through a simple and atom-economic neutralization reaction between N-alkyl morpholine and formic acid. Their densities, refractive indices, thermal properties, and electrochemical windows have been measured. The temperature dependence of their dynamic viscosity and ionic conductivity have also been determined. The results allow us to classify them according to a classical Walden diagram and to evaluate their "fragility". In addition, morpholinium based PILs exhibit a large electrochemical window as compared to other protic ionic liquids (up 2.91 V) and possess relatively high ionic conductivities of 10-16.8 mS.cm(-1) at 25 degrees C and 21-29 mS.cm(-1) at 100 degrees C, and a residual conductivity close to 1.0 mS.cm(-1) at - 15 degrees C. PIL-water Mixtures exhibit high ionic conductivities up to 65 mS.cm(-1) at 25 degrees C and 120 mS.cm(-1) at 100 degrees C for morpholinium formate with water weight fraction w(w) = 0.6. Morpholinium based PILs studied in this work have a low cost and low toxicity, are good ionic liquids, and prove extremely fragile. They have wide applicable perspectives as electrolytes for fuel cell devices, thermal transfer fluids, and acid-catalyzed reaction media as replacements of conventional solvents.
