Objective:
This project will exhaustively compile and critically evaluate published solubility data for binary and higher systems of nitriles C+3 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).
Description:
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 wide importance. The systems to be covered by this project fit into one of these priority areas, Solubility Related to Industrial Processes. Nitriles it is possible to use as solvents of extractive distillation for separation of homologues (water + benzonitrile + alcohols (ethanol, 1-propanol, 2-propanol, 1-butanol) and for separation of the higher aromatic and paraffin hydrocarbons (2-methoxypropanenitrile + 2-methylnaphthalene + hexadecane).
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.
