We present a method of continuous electroextraction of amino acids using aqueous two phase system in a microchip. The separations occur due to differences in electrophoretic mobility and solvent affinity. The results suggest the possibility of high levels of purification by controlling the electric field across the liquid barrier.

Three Phase

The oxidation of cyclohexane with H2O2 in a compressed CO2/acetic acid binary system was studied at 60.0 and 80.0°C, at pressures up to 18 MPa, and with the zeolite TS-1 as catalyst. The phase behaviour of the reaction system was also observed. There are three fluid phases in the reaction system at lower pressure but two at higher pressures. In the three-phase region the yields of the products, cyclohexanol and cyclohexanone, increase considerably with increasing pressure and reaches a maximum near the phase-separating pressure. CO2 can thus enhance the reaction effectively. However, the effect of pressure on the yield is very limited after the transition to a two-phase system.

Catalyst Efficiency

The metalloporphyrin catalytic oxidation of hydrocarbons using dilute hydrogen peroxide as oxygen donor with a two-phase system in the presence of an excess of benzoic acid is studied. Porphyrins derived from meso-tetrakis(2,6-dichlorophenyl)porphyrin and bearing sulfonamide substituents at β or meso positions and halogens at β positions were used. The system allowed for very efficient catalytic epoxidations and hydroxylations of hydrocarbons. It is proved that the excess of benzoic acid is critical to the catalyst efficiency and stability. The role of the lipophilic acid in this system is discussed.

Determining Factor

Benzyl β-ᴅ-glycosides of 2-acylamino-2-deoxy-ᴅ-glucopyranose are usually prepared by multistep processes employing the glycosyl halides. Mixtures of benzyl glycosides which contain predominantly the α-glycoside result from acid catalyzed reactions with benzyl alcohol in one phase. In a two phase system, however, the lower solubility of the β-ᴅ-anomer becomes the determining factor in the resultant tandem equilibrium, and the β-ᴅ-glycoside predominates in the final product.
