New Proposals for Supercritical Fluids Applications
Abstract Supercritical fluids (SCF) constitute a promising platform for future technological and environmental applications. The basic advantage of this method is their enormous selectiveness matched with a broad-range tuning of useful properties. So far, SCF technologies have made use of the vicinity of the gas — liquid critical point in a one component system, such as CO2. For specific applications an additional component may be used to reach the desired technological target. In this report novel possibilities associated with supercriticality near the liquid — liquid critical point in binary solutions of limited miscibility and in a one component fluid are presented. The latter is discussed for a weakly supercooled nitrobenzene and trans-1,2-dichlorethylene. For the critical consolute point the possibility of obtaining arbitrary values and sings of the pressure shift of the critical temperature dT C /dP are stressed.
