Vapour Pressure of Diethyl Phthalate

September 11, 2004

Author(s)

Vladimir Rohac, Kvetoslav Ruzicka, Vlastimil Ruzicka, Dzmitry H. Zaitsau, Gennady J. Kabo, Vladimir Diky, Karel Aim

Measurements of vapour pressure in the liquid phase and of enthalpy of vaporisation and results of calculation of ideal gas properties for diethyl phthalate are reported. The method of comparative ebulliometry, the static method, and the Knudsen mass loss

A Thermodynamic and Time Course Study of the Lipase-Catalyzed Transesterification of Benzyl Alcohol and Butyl Acetate in Supercritical Carbon Dioxide Media

August 16, 2004

Author(s)

Yadu D. Tewari, T. Ihara, Karen W. Phinney, M P. Mayhew

The time course and thermodynamics of the lipase-catalyzed transesterification reaction (benzl alcohol + butyl acetate = benzyl acetate + 1-butanol) has been studied in supercritical carbon dioxide (SCCO 2), n-hexane, toluene, and neat media (no solvent

Correlation for the Second Virial Coefficient of Water

March 4, 2004

Author(s)

Allan H. Harvey, Eric W. Lemmon

A new correlation has been developed to represent the second virial coefficient of water (H2O) as a function of temperature. The formulation was fitted to experimental data, both for the second virial coefficient itself and for a quantity related to its

ThermoML - An XML-Based Approach for Storage and Exchange of Experimental and Critically Evaluated Thermophysical and Thermochemical Property Data 2. Uncertainties

May 26, 2003

Author(s)

Robert D. Chirico, Michael D. Frenkel, Vladimir Diky, K N. Marsh, R C. Wilhoit

ThermoML is an XML-based approach for storage and exhange of experimental and critically evaluated thermophysical and thermochemical property data. Extensions to the ThermoML schema for the expression of uncertainties are described. Basic principles, scope

Thermodynamics of Enzyme-Catalyzed Reactions

March 1, 2003

Author(s)

Robert N. Goldberg, Yadu D. Tewari

This review, which has been prepared for the McGraw-Hill 2003 Yearbook of Science and Technology, gives an overview of the thermodynamics of enzyme-catalyzed reactions. Topics include the thermodynamic formalism(s) used in this field, computational methods

Arsenic Thermodynamic Data and Environmental Geochemistry

January 1, 2003

Author(s)

D K. Nordstrom, Donald G. Archer

Thermodynamic data are critical as input to models that attempt to interpret the geochemistry of environmentally important elements such as arsenic. Unfortunately, the thermodynamic data for mineral phases of arsenic and their solubilities have been highly

IUPAC Experimental Thermodynamics Volume VI: Measurement of the Thermodynamic Properties of Single Phases: CH. 3 Pressure; b) Piston Gauges

December 1, 2002

Author(s)

Charles D. Ehrlich, James W. Schmidt

The last twenty five years have seen significant advances in the technology and theoretical models associated with the use of piston gauges for the measurement of both pneumatic and hydraulic pressure. Most notably, the incorporation of computers and

Thermodynamic Quantities for the Ionization Reactions of Buffers in Water

December 1, 2002

Author(s)

Robert N. Goldberg, N Kishore, R M. Lennen

This table contains selected values for the pK, standard molar enthalpy of reaction {Δ} rH , and standard molar heat-capacity change {Δ} rC p for the ionization reactions of 64 buffers many of which are relevant to biochemistry and to biology. The values

How Fluids Unmix: Discoveries by the School of Van Der Waals and Kamerlingh Onnes

August 31, 2002

Author(s)

Johanna Levelt Sengers

This book narrates the story of pioneering scientists in the Netherlands, who reached a profound and comprehensive understanding of fluid mixture phase separation within a brief time span around the turn of the 19th century. This achievement was the

Correlation for the Vapor Pressure of Heavy Water From the Triple Point to the Critical Point

March 1, 2002

Author(s)

Allan H. Harvey, Eric W. Lemmon

A new formulation has been developed to represent the vapor pressure of heavy water (D 20) from its triple point to its critical point. This work takes advantage of several developments since the publication of the best previous formulation: the

Evaluated Enthalpies of Formation of the Stable Closed Shell C1 and C2 Chlorinated Hydrocarbons

March 1, 2002

Author(s)

Jeffrey A. Manion

Experimental data on the enthalpies of formation of chloromethanes, chloroethynes, chloroethenes, and chloroethanes are critically reviewed. Enthalpy of formation values for the C1 and C2 chlorinated hydrocarbons are highly cross-linked by various measured

Thermodynamics of the Lipase-Catalyzed Esterification of Glycerol and N-Octanoic Acid in Organic Solvents and in the Neat Reaction Mixture

November 1, 2001

Author(s)

Yadu D. Tewari, David M. Bunk

The thermodynamics of the lipase-catalyzed esterification of glycerol with n-octanoic acid have been investigated with acetonitrile, benzene, and toluene as solvents and in the neat reaction mixture (no organic solvent added). This esterification reaction
