Excess heat capacities of binary liquid mixtures determined with a Picker flow calorimeter

Thermodynamic and acoustic properties of binary mixtures of alcohols and alkanes. II. Density and heat capacity of (ethanol+n-heptane) under elevated pressures

“…Excess molar heat capacities of alkanol + alkane mixtures are positive at temperatures close to the room temperature under atmospheric pressure and they increase with increasing temperature [13][14][15][16]. The partial molar heat capacities of alkan-1-ols in alkanes are larger than molar heat capacities of pure alkan-1-ols.…”

“…That leads to smaller values of excess molar volumes (V E ) and relative excess (V E /V) at elevated pressures (figure 4) due to stronger hydrogen bonds caused by the r-bond cooperativity, according to the classification of Jeffrey [21]. The counteracting effects of pressure and temperature on the [13], (n) Fortier and Benson [14], (¤) Brown and Ziegler [15], and (h) Tanaka et al [16]. Lines calculated from equation (6).…”

Thermodynamics of mixtures involving some (benzene derivatives+benzonitrile)

“…Experimental densimetric and calorimetric techniques have been described in detail in previous works [19][20][21][22][23]. Densities, q, of pure components and their mixtures were measured with Picker densimeters (models 02D and 03DCss, SODEV, Canada), operated under flow conditions.…”

Excess volumes and isobaric heat capacities of diisopropyl ether with several alkanols at 298.15K

“…The instrumentation and procedures have been described in [3,4]. The volumetric heat capacity of the liquid flowing through the working cell is measured against that of the reference cell and each solution acted as reference for the next one.…”
