Estimation of vapor and liquid enthalpies
AIChE Journal, 1965AbstractThe Lydersen‐Greenkorn‐Hougen (L‐G‐H) charts correlating the isothermal pressure effects on enthalpy for pure compounds based on a modified corresponding states principle have been improved with the aid of reliable literature data. To facilitate machine computations, the improved charts, divided into the superheated vapor region, the subcooled ...

Vapor Pressures and Vaporization Enthalpies of a Series of Ethanolamines
Journal of Chemical & Engineering Data, 2005The vapor pressures and molar enthalpies of vaporization, Hm, of 2-amino-ethanol, 2-(methylamino)-ethanol, 2-(ethylamino)-ethanol, 2-(dimethylamino)-ethanol, and 2-(diethylamino)-ethanol have been determined using the transpiration method. The strength of intermolecular hydrogen bonding in ethanolamines has been derived and discussed in terms of the ...

Enthalpies of vaporization of some aliphatic alcohols
The Journal of Chemical Thermodynamics, 1971Abstract : A new calorimeter for measuring enthalpies of vaporization of pure liquids is described. Enthalpies of vaporization were determined over the temperature range 25 to 60C for the series of alcohols: methanol, ethanol, propanol, isopropanol, butanol, isobutanol, sec-butanol, and tert-butanol.

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.
