Polar Attributes of Supercritical Carbon Dioxide

摘要: Supercritical carbon dioxide (scCO2) is increasingly promoted as an environmentally benign alternative to conventional organic solvents. The supercritical state bridges the gap between liquid and gaseous states by offering gaslike diffusion rates liquidlike solvent densities, thereby enabling potential opportunities a reaction separation medium in chemical industry. Understanding behavior of scCO2 critical importance enable design CO2-philic molecular systems expand use these wider range processes. Historically CO2 was treated nonpolar solvent, primarily because its low dielectric constant zero dipole moment. has also been described quadrupolar significant quadrupole Recent studies suggest that, far microscopic concerned, act both weak Lewis acid base. Also, strong theoreti...
