Revised Group Additivity Values for Enthalpies of Formation (at 298 K) of Carbon-Hydrogen and Carbon-Hydrogen-Oxygen Compounds, p. 1411

N. Cohen

A program has been undertaken for the evaluation and revision of Group Additivity Values (GAVs) necessary for predicting, by emans of Benson's Group Additivity Method, thermochemical properties of organic molecules. This review reports on the portion of that program dealing with GAVs for enthalpies of formation at 298.15 K (hereinafter abbreviated as 298 K ) for carbon-hydrogen and carbon-hydrogen-oxygen compounds. A complete database of experimental data for gas, liquid, and crystal solid) phase enthalpies of formation is presented.

Extended Additivity Model of Parameter log(L16), p.1483

Pavel Havelec and Jiri G. K. Sevcik

An additivity model of the apolar solute-solvent parameter log(L16) was verified using sets of 939 nonaromatic and 1075 aromatic compounds. Unbiased distributions of errors and of the contribution significance level were statistically tested. An analysis of the CH2 group contribution in 34 homologous series indicates that the differences among the homologous series are statistically insignificant and related to interactional contributions rather than to the nature of the CHs group.

A New Equation of State for carbon Dioxide covering the Fluid Region from the Triple Point Temperature to 1100 K at Pressures up to 800 MPa, p. 1509

R. Span and W. Wagner

This work reviews the available data on thermodynamic properties of carbon dioxide and presents a new equation of state in the form of a fundamental equation explicit in the Helmholtz free energy. By applying state-of-the-art strategies for optimization of the mathematical form of the equation and for the simultaneous nonlinear fit to the data of all these properties, the resulting formulation is able to represent even the most accurate data within their experimental uncertainty. Special interst has been focused on the description of the critical region and the extrapolation behavior of the formulation. Without a complex coupling to a scaled equation of state, the new formulation yields a reasonable description even of the caloric properties in the immediate vicinity of the critical point. At least for the basic properties like pressure, fugacity, and enthalpy, the question can be extrapolated up to the limits of the chemical stability of carbon dioxide.

NIST-JANAF Thermochemical Tables for the Iodine Oxides, p.1297.

Malcolm W. Chase

The thermodynamic and spectroscopic properties of the iodine oxide species have been reviewed. Recommended NIST-JANAF Thermochemical Tables are given for six gaseous iodine oxides; IO, OIO, IOO, IOI, IIO, and IO3. In contrast to the chlorine and bromine oxides, the data are scarce and estimations must be made. Annotated bibliographies (over 350 references) are provided for all neutral iodine oxides which have been reported in the literature.

Electron Interactions with CF4, p.1341

L. G. Christophorou, J. K. Olthoff, and M. V. V. S. Rao

The available information on the cross sections and/or the rate coefficients for collisional interactions of CF4 with electrons is assessed and synthesized. Assessed information is presented on (1) cross sections for electron scattering, electron impact ionization, electron impact dissociation, and electron detachment; (2) coefficients for electron transport, electron attachment, and electron impact ionization; and (3) cross section sets derived from analyses of electron transport data.

Malcolm W. Chase

The thermodynamic and spectroscopic properties of the bromine oxide species have been reviewed. Recommended NIST-JANAF Thermochemical Tables are given for six gaseous bromine oxides: BrO, OBrO, BrOO, BrOBr, BrBrO, and BrO3. Annotated bibliographies (over 280 references) are provided for all neutral bromine oxides which have been reported in the literature.

I. Kleiner, F. J. Lovas, and M. Godefroid

The microwave spectrum of aetaldehyde is critically reviewed and supplemented with spectral frequency calculations derived from the rotation - internal rotation analysis. A simultaneous analysis of the torsional grount state, vt=0, and first and second torsionally excited states, vt=1 and 2, was carried out.

Thermodynamic Properties of Alkali Metal Hydroxides, Part I. Lithium and Sodium Hydroxides, p 1211

The data on the thermodynamic and molecular properties of the lithium and sodium hydroxides have been collected, critically reviewed, analyzed, and evaluated. Tables of the thermal functions of these hydroxides in the condensed and gaseous state have been calculated using the results of the analysis and some estimated values. The recommendations are compared with earlier evaluations.

A Modified Benedict-Webb-Rubin Equation of State for the Termodynamic Properties of R152a (1, 1-difluoroethane), p.605

Stephanie L. Outcalt and Mark O. McLinden

A modified Benedict-Webb-Rubin (MBWR) equation of state has been developed for R152a (1,1-difluoroethane). The correlation is based on a selection of available experimental thermodynamic property data. The MBWR equation established in this work may be used to predict thermodynamic properties of R152a from the triple-point temperature of 154.56 K to 500 K and for pressures up to 60 MPa except in the immediate vicinity of the critical point.

Liquid-Liquid Demixing from Solutions of Polystyrene. 1. A Review. 2. Improved Corelation with Solvent Properties, p. 637

Low pressure liquid-liquid demixing data for polystyrene dissolved in 76 different one-component solvent systems are reviewed and correlated. A new relation is developed which quantitatively correlates the area of solubility lying between the UCS and LCS demixing curves in the (TcMw-1/2) projection with solvent solubility parameters.

Volumetric Properties of Single Aqueous Electrolytes from Zero to Saturation Concentration at 298.15 °K Represented by Pitzer's Ion-Interaction Equations, p. 663

Boris S. Krumgalz, Rita Pogorelsky, and Kenneth S. Pitzer

The ion interaction approach developed by Pitzer allows the prediction of various thermodynamic characteristics of multiple-solute electrolyte solutions if the respective parameters for each type of single-solute electrolyte solutions are known. The present paper discusses the Pitzer Approach to the calculations of the volumetric properties of single-solute electrolyte solutions. The databases for the densities and the apparent molal volumes versus concentrations were created at 298.15 °K using essentially all published relevant data for each single-solute electrolyte solution.
