Thermodynamics of solutions of propanols in nonassociating components

Thermochimica Acta, 1985
Abstract The spectroscopic and thermodynamic properties of solutions of propanols in various nonassociating components can be described well by an associated solution model in which the association of alcohol molecules into open-chain and cyclic hydrogen-bonded species and the formation of complexes between the terminal hydroxyl group of the alcohol ...

Thermodynamic Properties of High-Temperature Air Components

1996
The paper gives a synthetic description of the basic methods to calculate the high-temperature thermodynamic properties of air species. Emphasis is given to the strong dependence of the electronic partition function and the thermodynamic properties of atomic species on the number of electronic levels taken into account.

Thermodynamics of solutions of methanol and solvating components

Thermochimica Acta, 1982
Abstract A model is proposed to correlate the excess Gibbs free energies and excess enthalpies of binary solutions of methanol and a solvating component. Solution nonideality from ideal solutions is given by the sum of the chemical contribution term, which is due to self-association of methanol and solvation between methanol and a nonassociating ...

Components and Thermodynamic Cycles

2019
Although many technical components, that are required to run energy conversion processes, have already been discussed previously, the focus in this chapter is on thermal turbo-machines as well as on heat exchangers. However, in this chapter the technical components are treated in steady state operation.

On dynamic and thermodynamic components of cloud changes

Climate Dynamics, 2004
Clouds are sensitive to changes in both the large-scale circulation and the thermodynamic structure of the atmosphere. In the tropics, temperature changes that occur on seasonal to decadal time scales are often associated with circulation changes. Therefore, it is difficult to determine the part of cloud variations that results from a change in the ...

Thermodynamics of Segregation in Multi-Component Alloys

MRS Proceedings, 1988
Thermodynamic equations are developed to express segregation in multicomponent alloys. These equations use concepts of excess partial free energies and activity coefficients and can be used in a wide variety of situations, including those where the segregating elements, such as sulfur, form strong chemical compounds in the bulk. A lower surface tension

Thermodynamics of Three-Component Systems

Nature, 1952
ALTHOUGH relations of the type where a is activity, n is number of moles, and the suffixes denote the components, are by no means new1, they have been little exploited. Further types such as and

Determination of volatile components of systems not in thermodynamic equilibrium

Talanta, 1987
A review is given of the literature on the analysis of complex mixtures of organic compounds and a procedure proposed for the separation and identification of the components of such mixtures. Retention data obtained with several chromatographic columns are combined with information from mass and Fourier-transform infrared spectra and identifications ...

The Thermodynamics of One-Component and Two-Component Elastic Systems

Textile Research Journal, 1950
The thermodynamic analysis of stress in one-component, one-phase elastic systems is reviewed, and it is suggested that the stress be evaluated in terms of entropy and enthalpy contributions. The analysis is then extended to two-component, two-phase systems, and the necessary equations are derived.
