Supercritical fluids: Clean solvents for green chemistry

Supercritical fluids are becoming increasingly attractive as environmentally acceptable replacement for organic solvents in chemical reactions and material processing. This paper highlights some of the properties of supercritical fluids, especially supercritical CO2, which offer particular advantages for the handling of polymers, metal complexes and the environmentally more friendly synthesis and manufacture of chemicals. The paper in: eludes some of the researches in University of Nottingham and a number of recent reviews which together provide a comprehensive introduction.
