Heat capacity and enthalpy of fusion of penconazole (C13H15Cl2N3)

Thermochimica Acta, 2004
Abstract Low-temperature heat capacities of penconazole (C 13 H 15 Cl 2 N 3 ) were precisely measured with an automated adiabatic calorimeter over the temperature rang from 78 to 364 K. The sample was observed to melt at 332.38±0.06 K. The molar enthalpy and entropy of fusion of the compound were determined to be 33580±11 J mol −1 , 101.03±0.02 J mol

Estimation of sublimation enthalpies of aromatic amides at 298.15 K from the values of fusion enthalpies

Thermochimica Acta, 2016
© 2016 Elsevier B.V.In this work a method for determination of sublimation enthalpies of amides substituted in aromatic ring from data on fusion enthalpies at the melting temperature was proposed. This method was checked by calculation of sublimation enthalpies of 12 substituted benzamides, containing −CH3, −OCH3, −F, −OH, −NH2 and −NO2 substituents ...

Enthalpy of fusion and cryoscopic constant for ethylene carbonate

The Journal of Chemical Thermodynamics, 1975
Abstract Because of a discrepancy in the literature, the enthalpy of fusion of ethylene carbonate has been redetermined. The value obtained is (35.80 ± 0.20) cal th g −1 which leads to (5.32 ± 0.03) K kg mol −1 for the molar frezing-temperature-depression constant.

ENTHALPY AND ENTROPY OF FUSION OF ISOTACTIC POLYSTYRENE

1967
ABSTRACT The enthalpy of fusion Δ H u of isotactic polystyrene, determined from measurements of the depression of the melting point of the polymer in the presence of diluents by the dilatometric method at equilibrium, was 2150 cal/structural unit (±100).

Enthalpy of fusion and cryoscopic constant of N-methylacetamide

The Journal of Chemical Thermodynamics, 1969
Abstract In view of a discrepancy in the literature, the enthalpy of fusion of N-methylacetamide has been redetermined. The value obtained is (31.78±0.16) cal g−1. The cryoscopic constant calculated from this result is (5.77±0.02) K kg mol−1.

Enthalpies of Fusion and Transition of Organic Compounds

1995
The temperatures and the enthalpies of both solid-solid and solid-liquid phase transition were collected from the original literature published from the end of the last century to early 1995. All the values were critically evaluated to provide recommended values in the cases where several experimental values were reported for the same phase transition.
