In this paper we describe the results obtained following the dissolution of copper precursors in supercritical carbon dioxide instead of conventional solvents. The precursors investigated have been restricted to co-ordination compounds of copper. The solubilities of copper acetylacetonate in supercritical CO2, as measured using a dynamic saturation technique, are reported at pressures between 100 and 200 bar and at two temperatures: 312.0K and 332.0K: for copper heptadionate solubilitites are reported at 312.0 K and in the pressure range of 100-200 bar. Other coordination compounds of copper were sintetized and their solubilities ar 312 K and 200 bar were determined. A row scale of solubilities in supercritical CO2 was been established.

Abstract
In this paper we describe the results obtained following the dissolution of copper precursors in supercritical carbon dioxide instead of conventional solvents. The precursors investigated have been restricted to co-ordination compounds of copper. The solubilities of copper acetylacetonate in supercritical CO2, as measured using a dynamic saturation technique, are reported at pressures between 100 and 200 bar and at two temperatures: 312.0K and 332.0K: for copper heptadionate solubilitites are reported at 312.0 K and in the pressure range of 100-200 bar. Other coordination compounds of copper were sintetized and their solubilities ar 312 K and 200 bar were determined. A row scale of solubilities in supercritical CO2 was been established.Pubblicazioni consigliate
