Enthalpies of solution, enthalpies of fusion and enthalpies of solvation of polyaromatic hydrocarbons: Instruments for determination of sublimation enthalpy at 298.15K

Thermochimica Acta, 2015
Abstract In this work a simple method for calculation of solvation enthalpies of polyaromatic hydrocarbons (PAHs) in various solvents at 298.15 K was proposed. According to this method the enthalpy of solvation of any polyaromatic hydrocarbon in a particular solvent can be calculated on the basis of the general formula of the compound, the solvation ...

The Enthalpy of Fusion of Gallium

Journal of Chemical & Engineering Data, 2002
An adiabatic calorimeter was used to measure the enthalpy of fusion of a very pure sample of gallium. The new value of the enthalpy of fusion was determined to be ΔfusH = 80.097 ± 0.032 J·g-1, where the uncertainty corresponded to a 95% confidence interval. A comparison with previous determinations is made.

Enthalpy of Fusion of Nematogens

Molecular Crystals and Liquid Crystals, 1977
Abstract The enthalpy of fusion of nematic compounds is an important parameter related to the use of such materials in displays. Since no single material is adequate in nematic range for use in displays, a substantial amount of work is required in preparation and evaluation of mixtures.

The enthalpy of fusion of anorthite

Contributions to Mineralogy and Petrology, 1980
The high-temperature enthalpies of liquid and glassy CaAl2Si2O8 were measured by drop calorimetry using a diphenyl ether drop calorimeter. These data are combined with published values of the high-temperature enthalpy of crystalline anorthite and the enthalpy of vitrification of anorthite to obtain the enthalpy of fusion of anorthite.
