Concentration dependences of heat capacity of ammonium iodide solutions in mixed N-methylpyrrolidone-water solvent at 298.15 K

The specific heat capacities (ср) of ammonium iodide solutions in the mixed solvent N-methylpyrrolidone (MP)-water in the whole range of compositions were measured by calorimetric method at 298.15 K. The influence of the mixed solvent composition on the heat capacity of three-component NH4I−MP−Н2О systems was analyzed. Standard values of partial molar heat capacities of NH4I in the mixed solvent MP-water at 298.15 K are calculated.

Abstract

The specific heat capacities (ср) of ammonium iodide solutions in the mixed solvent N-methylpyrrolidone (MP)-water in the whole range of compositions were measured by calorimetric method at 298.15 K. The influence of the mixed solvent composition on the heat capacity of three-component NH4I−MP−Н2О systems was analyzed. Standard values of partial molar heat capacities of NH4I in the mixed solvent MP-water at 298.15 K are calculated.
