When perfluorodecalin was used as solvent the distribution coefficients of phenolic compounds were very low and the concentrations in the aqueous phase
high enough to regard [C.
There are two other ways in which the hydrophobic segments of a surfactant can be isolated from the aqueous phase
2+] concentration distribution along the length of the module for different values of aqueous phase
flow rates is demonstrated in Fig.
p/w] is reported at an initial aqueous phase
concentration of 2000 mg/L (a) Poly(butylene terephthalate)-block-poly(butylene ether glycol terephthalate) (b) Poly(ethylene-co-vinyl acetate) Table 2.
After the pigment agglomerates are broken apart and the particles are dispersed in the aqueous phase
during the milling process, the particles must be stabilized to prevent flocculation.
8) There are complex interactions of thesecomponents with the HEUR thickener in the aqueous phase
that will be discussed in a later articles that may account for the different dilution effects noted in Fig.
When the organic solution is dispersed in the aqueous phase
, water starts diffusing into it, forming water droplets surrounded by polyester chains terminated by carboxylate anions positioned at the water/oil interface (Fig.
2003, "Biological decol- orization of simulated azo dye in aqueous phase
by algae Spirogyra species", Int.
The microparticles were prepared with changing concentrations of external aqueous phase
, internal aqueous phase
and saturated and unsaturated external aqueous phase
The ability to do organic chemistry in the aqueous phase
has become of great interest in the last several years in order to make these processes safer and less environmentally harmful.
The evaporated solvent is recovered, and the stabilized particles isolated from the aqueous phase
by standard techniques.
The technology is based on the Aqueous Phase
Reforming process, which Virent has exclusively licensed from the Wisconsin Alumni Research Foundation.
It was observed by Sankarshana and Rao (2003) that the concentration of potassium permanganate in the aqueous phase
at any particular time interval was the same for the stirrer speeds in the range of 350-800 rpm indicating that the agitation is unimportant for the stirrer speeds in this range.
The primary emulsion was added to an external aqueous phase
(W2)--a denatured whey protein isolate solution--at a ratio of 30:70 at a moderate mixing rate of 3200 rpm for 3 minutes.
Virent's patented BioFormingTM process is the first commercial application of Aqueous Phase
Reforming, a unique and innovative pathway to biofuel and bioproduct production.
