Abstract
The relationship between heats of mixing and chemical interactions has been investigated and is now discussed for three liquid binary systems, i. e. diethyl ether-chloroform, nitromethane-sulfuric acid, and isopropanol-isopropylamine. On the basis of a suitable equilibrium model, involving the formation of only one species of intermolecular compounds, equations HM= ƒ (N0 Δ) (HM=heat of mixing, N0 Δ =mole fraction of component A) are derived. The equations are convenient for representing the experimental data of symmetrical mixing curves, and they also allow us to calculate the thermodynamic quantities of the pertaining equilibrium reactions. Plotting HM versus N0 Δ/ (—HM) should give a straight line over the whole concentration range, thus warranting a reliable criterion for the applicability of the equilibrium model. The heats of mixing were measured at 25° and 20°, respectively, using a new type of continuous dilution calorimeter, which supplied a sufficient number of accurate experimental data.
