Diffusion and viscosity in gas-expanded liquids
Gas-expanded liquids are a new class of tunable solvents in which novel applications in separations and catalysis depend on the interactions of solutes with the cybotactic region. Diffusion coefficients of benzene, pyridine, pyrimidine, pyrazine, and 1,3,5-triazine by the Taylor-Aris dispersion technique in CO<inf>2</inf>-methanol mixtures are presented. Viscosities of the CO<inf>2</inf>-methanol mixtures are determined by measuring the pressure drop across a tube. These data will be compared with measurements of viscosity in the cybotactic region obtained by the rotation of a chromaphore. The comparison of these with the Stokes-Einstein relationship will help elucidate differences between bulk and local properties. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).

Switchable solvents for recovering homogeneous catalysts
, ISSN: 0065-7727To enjoy the benefits of homogeneous reactions with heterogeneous separations, novel solvent systems called Organic-Aqueous Tunable Systems are designed. Adding CO <inf>2</inf> to a miscible water-organic system, e.g., THF and water, will cause a phase split since the addition of CO <inf>2</inf> to THF increased the hydrophobicity of the THF. Hydrophobic reactants and a hydrophilic catalyst can be dissolved in one aqueous-organic solution. Once the reaction has been run homogeneously, CO <inf>2</inf> pressure can be used to split the water from the organic phase allowing for an easy separation of product and catalyst. The water and catalyst can now be easily recycled. This technique can be used with existing aqueous biphasic reactions to eliminate any mass transfer limitations; similar systems are also applicable for biocatalysis to bring substrates into intimate contact with the enzyme catalyst. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
