Enthalpies of vaporization of some β-diketones
J. Chem. Soc., Dalton Trans., 1975Molar enthalpies of vaporization of six β-diketones have been measured at 298·15 K by a direct calorimetric method; for 1,1,1,5,5,5-hexafluoropentane-2,4-dione, ΔHv0= 7·31 ± 0·03 kcal mol–1, 1,1,1-trifluoropentane-2,4-dione, 8·90 ± 0·4, 2,6-dimethylheptane-3,5-dione, 13·40 ± 0·04, 2,2-dimethylheptane-3,5-dione, 13·59 ± 0·03, 2,2,6-trimethylheptane-3,5 ...

Saturated vapor pressure, critical state parameters and vaporization enthalpy of 2-Phenyloxirane
Fluid Phase Equilibria, 2021Abstract The saturated vapor pressure of 2-phenyloxirane (PhOxi) was determined using a rose type equilibrium cell at different temperatures ranging from 303.15 K to 465.65 K. The experimental data were fitted with the Antoine and Clarke−Glew equations by minimizing the error of the maximum likelihood objective function using Britt – Luecke algorithm,

Enthalpy-Entropy compensation in food vapor adsorption
Journal of Food Engineering, 1996Abstract Enthalpy-entropy compensation was analysed for sorption isotherms of potatoes, macadamia nuts, apricots, figs, currants, prunes and raisins. Plots of (ΔHdif)T vs (ΔSdif)T for potatoes and macadamia nuts presented two isokinetic temperatures: TB1 = 272.0 ± 57.7 K (− 1 °C) for potatoes, TB1 = 265.0 ± 18.8 K (− 8 °C) for macadamia nuts and TB2 =

Calculating the Enthalpy of Vaporization for Ionic Liquid Clusters
The Journal of Physical Chemistry B, 2007Classical atomistic simulations are used to compute the enthalpy of vaporization of a series of ionic liquids composed of 1-alkyl-3-methylimidazolium cations paired with the bis(trifluoromethylsulfonyl)imide anion. The calculations show that the enthalpy of vaporization is lowest for neutral ion pairs. The enthalpy of vaporization increases by about 40

Vapor heat capacities and enthalpies of vaporization of five alkane hydrocarbons
The Journal of Chemical Thermodynamics, 1981Abstract Experimental values of vapor heat capacity for the real gas and enthalpy of vaporization, determined by vapor-flow calorimetry, are reported for n -pentane, 2,2-dimethylpropane, 3,3-dimethylpentane, n -octane, and 2,3,4-trimethylpentane. The results were used to derive values of C p o , the heat capacity in the ideal-gas state, and to

Vapor Pressure and Enthalpy of Vaporization of 2-Amino-3-methylpyridine
Journal of Chemical & Engineering Data, 2007The vapor pressure of 2-amino-3-methylpyridine was measured in the temperature range of (328.70 to 499.88) K using the boiling point method. The Antoine equation was used to describe the vapor pressure data, and the parameters in the equation were determined by means of the least-square regression method.
