Determination of enthalpy of fusion of K3FSO4
Thermochimica Acta, 1992Abstract The enthalpy of melting of K3FSO4 at 1148 K has been determined using a hightemperature calorimeter, the Setaram HTC 1800 K. ΔfusHm(K3FSO4 is found to equal 86 ± 3 kJ mol−1. The given error is calculated at the level of reliability (1 - α) = 0.95.

Fusion enthalpy and entropy of syndiotactic polystyrene
Polymer, 1990Abstract The fusion enthalpy and entropy of a highly syndiotactic polystyrene sample were determined by melting point depression in the presence of diluents. Three solvents were used to ascertain the presence, if any, of polymorphic modifications: dioctyl phthalate, diphenylsulphone and diphenyldiketone (benzil).

Enthalpie et Entropie de Fusion du Polystyrolène Isotactique
Bulletin des Sociétés Chimiques Belges, 1959AbstractL'enthalpie ΔHu et l'entropie ΔSu de fusion du polystyrolène isotactique ont été déterminées à partir de mesures d'abaissements de la température de fusion que présente un échantillon donné quand on lui additionne des quantités variables d'un diluant.

Determination of the enthalpy of fusion of Na3FSO4
Thermochimica Acta, 1991The areas of the fusion and crystallization peaks of Na3FeF6 and of four calibration substances (KCl, NaCl, Na2SO4, and K2SO4) were measured using the DSC mode of a high-temperature calorimeter. Using the measured quantities and known values of the enthalpy of fusion of the calibration substances, the enthalpy of fusion of Na3FeF6 was determined.

The Journal of Chemical Thermodynamics, 1993
Abstract The molar enthalpy and temperature of fusion of a very pure sample of indium have been determined by adiabatic-shield calorimetry for the Laboratory of the Government Chemist, U.K. with the result: Δ fus H m = (3296±9) J·mol -1 . Fractional-enthalpy-of-fusion determinations over the region (13.4 to 88.0) per cent molten indium are ...

Fusion enthalpy and entropy of isotactic polypropylene
European Polymer Journal, 1968Abstract The “equilibrium melting temperature” of isotactic polypropylene and of a number of its mixtures with hexadecane, α-chloronaphthalene, decalin and naphthalene is determined by extrapolation of several experimental melting temperature data obtained by rapid melting of each sample isothermally crystallized at different temperatures.

Molar enthalpies of sublimation of 1,2,4-, 1,2,3-, and 1,3,5-tri-hydroxy-benzene, were obtained from the temperature dependence of the vapor pressure measured by the transpiration method. The molar enthalpies of fusion and molar heat capacities of these compounds were measured by DSC.

Estimating entropies and enthalpies of fusion of hydrocarbons
The Journal of Organic Chemistry, 1990A group additivity method for estimating fusion entropies and fusion enthalpies is described. The method is based on experimental fusion enthalpies of 191 hydrocarbons. Group values are provided for most structural environments. Applications of the technique are described, and comparisons with literature values and other estimation techniques are also ...

Determination of the enthalpy of fusion of K3NbO2F4
Chemical Papers, 2011AbstractAreas of fusion and crystallization peaks of K3NbO2F4 were measured using the DCS mode of a high-temperature calorimeter (SETARAM 1800 K). On the basis of these quantities, considering the temperature dependence of the calorimeter sensitivity, the value of the fusion enthalpy of K3NbO2F4 of (98 ± 6) kJ mol−1 was determined at the fusion ...
