Objective:
To update and extend Monograph No.6 to Journal of Physical and
Chemical Reference Data "Heat Capacity of Liquids: Critical
Review and Recommended Values", by M. Z�bransk�, V. Ru�icka, V.
Majer, and E.S. Domalski, published in 1996, that contained recommended
data on liquid heat capacities for over 1600 pure, mostly organic
compounds. The publication was the product of IUPAC Project 121/11/87.
Description:
New experimental data on heat capacities of pure liquid organic
and some inorganic compounds will be compiled, critically evaluated
and recommended values provided. The bulk of the compiled data will
cover data published in the primary literature between 1993 and
1999 and some data of 2000. However, some data from older sources
will be also included.
Recommended data presented in terms of parameters of correlating
equations for temperature dependence of heat capacities of liquids
will be developed by critical assessment of literature calorimetrically
determined heat capacities. The work will be an update of a two
volume monograph, that was published in 1996 as a Monograph No.6
of the Journal of Physical and Chemical Reference Data. The
updated and extended database will contain data for about 720 compounds.
Firstly, the new data entail heat capacities for about 350 compounds
not included in the Monograph No.6. Secondly, new data that either
extend the temperature range of recommended data for compounds already
presented in the Monograph No.6 or improve the overall uncertainty
of the recommended data by supplying new data that have a lower
error of measurement were added for more than 320 compounds. Thirdly,
references to new data for about 50 compounds are presented in a
review of primary sources only as the data for such compounds do
not extend or improve the previously developed recommended data.
Newly published data were taken from almost 360 literature references.
Progress :
This project was presented as a poster at the 9th
International Conference on Properties and Phase Equilibria for
Product and Process Design, 20-25 May 2001, Kurashiki, Japan.
