Organic liquids unique aspects

Microemulsions tremendously expand the potential applications of supercritical fluids as reaction media for chemical reactions. By themselves, near-critical and supercritical fluids are much weaker solvents than the typical organic liquid. However, microemulsions create a highly polar region that is capable of solvating polar catalysts, reactants, or products. The unique aspects of the near-critical or supercritical continuous phase offer many advantages over their liquid-phase analogs. 

The solubility of drugs and ottier solids determines whether tiiey can be placed into (he aqueous phase. For drugs, water solubility is a critical consideration, since it correlates with bioavailability and toxicology. It is also important for sample preparation and cleanup, because most liquid-liquid extractions involve an aqueous phase in contact with an organic phase. The only unique aspect of solubility equilibrium is that, since one component is a solid, it is not expressed, because ttiere is no aqueous concentration. The solubility is referred to as S and is obtained as shown in Example Problem 4.2. 

Small atom with a big ego was the title of the ACS Symposium in San Francisco in 2000, where a number of current scientific and industrial aspects of fluorine-related chemistry were discussed. This small atom has been providing mankind with a lot of benefits, in the form of special products such as Teflon , freon, fluoro-liquid crystals, pharmaceutical and agrochemical compounds, and so on, all of which have their own unique properties created by the characteristic nature of fluorine. Nowadays, organic fluorine compounds have attracted a great deal of interest from the scientists involved in many fields of science and technology.
