ternary and other multicomponent systems

Completion Date: 2007 - project completed
This project will exhaustively compile and critically evaluate published
solubility data for ternary and higher systems of acetonitrile with
all other components. The results of this work will be prepared in the
standard format of the IUPAC-NIST Solubility Data Series for publication
in the Journal of Physical and Chemical Reference Data and for
inclusion in a web-accessible database being prepared by the US National
Institute of Standards and Technology (NIST).
The IUPAC Solubility Data Project (SDP) compiles and critically evaluates
data on chemical solubility and disseminates the resulting information
to the widest possible range of users by traditional (printed on paper)
and electronic (web-accessible database) means. Under the direction
of the Subcommittee on Solubility
and Equilibrium Data (SSED) of the Analytical
Chemistry Division, the SDP has focused on five subject areas of
The systems to be covered by this project fit into one of these priority
areas, Solubility Related to Industrial Processes. Acetonitrile is one
of the best extractive distillation solvents for separation of close
boiling paraffinic and olefinic hydrocarbons (hydrocarbons C5 + acetonitrile
+ water: isoprene + acetonitrile + water, trimethylethene + acetonitrile
+ water, isopentane + acetonitrile + water) and for the separation of
paraffinic and aromatic hydrocarbons (hexane + benzene + acetonitrile
Others nitriles are used for separation of 1-alcohols, for example,
water + benzonitrile + ethanol (1-propanol, 2-propanol, 1-butanol).
As the chemical process industry seeks more efficient and less energy-intensive
separation techniques, liquid-liquid extraction based on selective solubilities
are becoming more common.
