Molar heat capacities of the mixture {1, 8-cineole + ethanol} at several temperatures and atmospheric pressure

Molar heat capacities at atmospheric pressure have been determined every 5 K for the mixture {1, 8-cineole (1) + ethanol (2)} in the temperature interval (304.7 to 324.5) K and the whole composition range with a Calvet type calorimeter Setaram C80. From the molar heat capacities, excess molar heat capacities have been calculated, their values being positive and increasing as the temperature rises. The solvation model COSMO-RS has been applied to predict the excess molar heat capacities. The model overestimates the values of the excess heat capacities but predicts well the trend of variation of the excess molar heat capacity with the temperature

Thermal conductivity of ammonia + lithium nitrate and ammonia + lithium nitrate + water solutions over a wide range of concentrations and temperatures

10.1016/j.ijrefrig.2013.08.010The thermal conductivity of NH3 + LiNO3 and NH3 + LiNO3 + H2O mixtures with an ammonia mass fraction between 0.3 and 0.6 was measured at temperatures from 303.15 K to 353.15 K at 1.5 MPa, using a relative transient hot wire apparatus. The apparatus and method were validated by comparing the measured values of the thermal conductivity of pure water, toluene, dimethyl phthalate, ethylene glycol and water + lithium nitrate with published values. Uncertainty in the measurements was estimated to be less than 0.025 W m-1 K-1. The measured NH3 + LiNO3 thermal conductivity was compared with the literature, showing significant differences. Finally, the experimental data was fitted with a comprehensive model based on the local composition concept
