2000, brief summary
Summary of Minutes of Commission Meeting at Halifax, Nova
Scotia, 5-6 August 2000
Twenty-two members of the Commission on Thermodynamics
(I.2), including national representatives and observers, met for two
days of discussions during the 16th
IUPAC Conference on Chemical Thermodynamics.
Several projects had been completed and the results
published, including the following: Conductivities, Transference Numbers,
and Limiting Ionic Conductivities of Solutions of Aprotic Protophobic
Solvents, by J. Barthel and R. Neueder, II. Carbonates, Dechema Chemistry
Data Series, Vol. XII, Part 1d; and Theory
of Equations of State for Fluids and Fluid Mixtures, edited by J.
V. Sengers et al. (Elsevier, September 2000).
In addition, there are several projects that are close
to completion. Part 1e in the series Conductivities, Transference
Numbers, and Limiting Ionic Conductivities of Solutions of Aprotic
Protophobic Solvents: III Various Solvents; and Parts 1e: I. Amides
and 1f : II. Various Solvents in the series Conductivities, Transference
Numbers, and Limiting Ionic Conductivities of Solutions of Protophilic
Solvents, by J. Barthel and R. Neueder, are in preparation. A volume
on Vapor Pressures, Osmotic, and Activity Coefficients of Nonaqueous
Solutions is also in preparation. M. A. V. Ribeiro da Silva presented
a final draft of Thermochemistry of Chemical Reactions. Publication
is planned in the Journal of Chemical Thermodynamics and in
Pure and Applied Chemistry (PAC), following the IUPAC publication
procedure. Changes to the manuscript on 'Legendre transforms in chemical
thermodynamics' have been agreed upon by Prof. Alberty and Prof. Schiffrin
(Commission I.3), and the revised manuscript has been submitted to
PAC and to the Journal of Chemical Thermodynamics. Experimental
Thermodynamics Volume VI. Measurement of the Thermodynamic Properties
of Single Phases, Editors: A. R. H. Goodwin, K. Marsh, and W. A. Wakeham;
and Volume VII. Measurement of the Properties of Multiple Phases,
Editors: T. W. de Loos and R. D. Weir are well advanced. It was anticipated
that all sections would be completed by the end of 2000, by which
time it was hoped that the problem of finding an alternative publisher
to Blackwell Science will have been resolved. I. Wadsö presented
a revised manuscript entitled 'Standards in Isothermal Microcalorimetery',
which will be submitted following the IUPAC procedure for publication.
Della Gatta presented his final draft of 'Standards for Differential
Scanning Calorimetry'. After further discussion at the August 2000
ICTAC meeting in Copenhagen, this paper was also to be submitted for
publication in the Journal of Chemical Thermodynamics, Thermochimica
Acta, and Calorimetry and Thermal Analysis. Possible new projects
discussed included 'Guidelines for publication of equations of state
II. Mixtures' (U. K. Deiters) and 'Global phase diagrams of fluid
mixtures' (U. K. Deiters and T. M. Boublik).
It was reported that the Journal of Chemical Thermodynamics
had a steady increase in the number of manuscripts submitted, with
152 papers accepted in 1999 and a journal size of 1 644 pages. M.
A. White announced that there would be more than 500 participants
at the 16th IUPAC International Conference on Chemical
Thermodynamics (ICCT) to be held 6-11 August 2000 in Halifax (see
symposia report), with 120 accompanying persons, from a total
of 42 countries and in excess of 500 presentations in 8 parallel oral
sessions. The Commission members approved plans for the 17th
ICCT, which will be held 28 July-2 August 2002, in Rostock, Germany
conference announcement). The invitation of Prof. Hai-Ke Yan to
host the 18th ICCT in Beijing, China 22 -27 August 2004
was officially accepted. A diskette will be prepared to supplement
the Guidebook for Organizers of IUPAC ICCTs to assist prospective
organizers of these meetings.
The Subcommittee on Thermodynamic Data has been active
in the following areas: In the series of publications on Critical
Compilation of Vapor Liquid Critical Properties, 'Part 7. Oxygen Compounds
other than Alkanols and Cycloalkanols' has been submitted for publication
in the Journal of Chemical and Engineering Data. Completion of the
work on nitrogen-containing compounds, on halogenated compounds, and
on polyfunctional compounds is planned for late 2001. Publication
of Vol. 14 (Benzene) and Vol. 15 (Carbon Dioxide) in the series on
International Thermodynamic Tables of the Fluid State (Project Leader,
W. A. Wakeham) is expected in 2001. The first workshop of the project
on 'Thermochemical, thermodynamic, and transport properties of halogenated
alkanes and their mixtures' was very successfully organized by Prof.
Matteoli in Pisa 15-18 December 1999 (see report in CI, Vol. 22, No.
6, p. 162, 2000). There were 88 participants, with 8 invited lectures,
28 oral, and 34 poster presentations. The scope of this meeting was
quite general, with a concluding roundtable discussion to identify
the key systems and topics for future work. Eighteen selected papers
will be published later this year in a special issue of Fluid Phase
Equilibria, with Matteoli and Deiters as Guest Editors. The second
workshop will be held 9-11 April 2001 in Fontainebleau, France, and
will be organized by Dominique Richon (see announcement in CI, Vol.
23, No. 1, p. 25, 2001). Selected papers will be published in Fluid
Phase Equilibria, with J. Dymond and D. Richon as Guest Editors. A.
Heintz reported the intention to start a new project on Ionic Liquids
(low-temperature organic molten salts). It is proposed to produce
a supplement to the two volumes on Heat Capacity of Liquids, published
as Journal of Physical and Chemical Reference Data Monograph 6 in
The Subcommittee on Transport Properties met in Boulder,
Colorado, USA in June 2000. More than 30 people attended, and there
were 8 scientific presentations. The next meeting of the Subcommittee
will be held in Thessaloniki, Greece in September 2001. Under the
heading 'Definitive correlation of transport properties of fluids',
work has been completed on the 'Viscosity of toluene at atmospheric
pressure/saturation line'; 'Viscosity of toluene as a function of
pressure'; and 'Viscosity of isobutane'. Work is continuing on 'Viscosity
of liquid water'; 'Transport properties of methane + ethane'; 'Transport
properties of butane'; 'Viscosity and thermal conductivity of water
and steam'; 'Viscosity of pentane'; 'Viscosity of cyclopentane'; and
'Viscosity of alkali chlorides'. New subprojects include 'Thermal
conductivity of isobutane' and 'Correlation of thermal conductivity
Recent publications under the auspices of the Subcommittee
include the following: E. Vogel, C. Kuchenmeister, E. Bich. 'Viscosity
correlation for isobutane over wide ranges of the fluid region', International
Journal of Thermophysics 21, 343-357 (2000); M. J. Assael, E. Bekou,

It was agreed to set up a Commission web site to advertise
conferences and current projects, to list publications, to provide
links to educational tools, to give information on databases, and
to provide an opportunity for comment on new proposals and suggestions
for feasibility studies. In order to continue the important work of
the Commission after 2001, it was resolved to set up an International
Committee on Chemical Thermodynamics (ICCT). It was agreed that:
