Dissolution enthalpies of anhydrous sodium sulfate in water were measured up to saturation atT = (287.8, 317.5, and 352.1) K with a SETARAM C80 mixing calorimeter. Experimental isotherms, and previous ones at T = 297.6 K and T = 317.5 K (Hubert, N. e

In this paper, we present a methodology for the prediction of the crystallization enthalpy of mirabilite (Na 2 SO 4 ·10H 2 O) from supersaturated H 2 O–NaCl–Na 2 SO 4 solutions. Required thermodynamic properties of H 2 O–NaCl–Na 2 SO 4 such

Pitzer's model has been used to calculate various thermodynamic properties of NaCl–Na2SO4–H2O system. A methodology taking into account enthalpy and solubility data has been proposed. This leads to the proposal of a unique set of parameters allow

The dissolution enthalpy of sodium chloride in water was measured until saturation at 24.4°C, 44.3°C and 59.2°C using a C80D differential calorimeter (SETARAM). The experimental data were fitted using Pitzer's ion interaction model and the value o

Drop calorimetry has been used to measure the heat changes occurring upon the dissolution of some single n -alkanes (octadecane to tetracosane) or their binary mixtures (C 22 H 46 C 24 H 50 and C 23 H 48 C 24 H 50 ), in ethylbenzene, at 311.45

Bien que, dans la pratique, les applications industrielles concernent surtout les systemes contenant un grand nombre d’especes chimiques, il serait reducteur de considerer que l’ingenieur n’est pas interesse par les systemes monoconstituants. E
