Solubility of several short-chain lithium dialkyldithiocarbamates in liquid and supercritical carbon dioxide.

The solubility of lithium diethyldithiocarbamate, lithium dipropyldithiocarbamate, lithium dibutyldithiocarbamate, and lithium bis(trifluoroethyl)dithiocarbamate was measured in liquid and supercritical carbon dioxide at (298, 308, and 318) K and at pressures between (80 and 250) bar. The solubilites were measured experimentally through traditional cloud point observations using a variable-volume stirred vessel with a sapphire window for visual inspection of the contents. These four short-chain lithium dialkyldithiocarbamates showed an increase in solubility with increasing density (or pressure) at fixed temperature. This increase was fairly independent of the temperature. Solubilites also increased with increasing temperature. The data were accurately modeled using an equation derived from association laws, which had a strong solvent density and temperature dependence.
