摘要

在 298.15 K (cp) 温度下，通过量热法测量了碘化铵溶液在 N-甲基吡咯烷酮（MP）-水混合溶剂中的整个成分范围内的比热容。分析了混合溶剂的成分对三组分 NH4I-MP-H2O 系统热容量的影响。计算了 298.15 K 时 NH4I 在 MP-水混合溶剂中的部分摩尔热容标准值（{{\overline {C_{p}^{0}} }_{2}}）。

Concentration Dependences of the Heat Capacity of Ammonium Iodide Solutions in Mixed N-Methylpyrrolidone–Water Solvent at 298.15 K

Specific heat capacities are measured via calorimetry at 298.15 K (c_p) for solutions of ammonium iodide in a mixed N-methylpyrrolidone (MP)–water solvent throughout the range of compositions. The effect the composition of the mixed solvent has on the heat capacity of three-component NH₄I–MP–H₂O systems is analyzed. Standard values of partial molar heat capacities \({{\overline {C_{p}^{0}} }_{2}}\) are calculated for NH₄I in a mixed MP–water solvent at 298.15 K.
