Throw away aqueous phase;
Thus, the problems associated withextremely low solubility of the organic reactants in the aqueous phase can be overcome.
The solid-in-oil mixture is added to an aqueous phase of PVA(w/v) to form a S-O/W emulsion.
In case of a solvent extraction, a solvent(e.g. an organic solvent)is used to dissolve and separate a compound from a another liquid(e.g. an aqueous phase).
Sonication is capable of disrupting the oil and aqueous phases and mixing tiny oil droplets into water.
In general, biomolecules are recovered in a purified form at the interphase,while the contaminants mostly partition to t-butanol(top phase) and to the aqueous phase(bottom phase). .
The specific gravity of the aqueous phase can be adjusted through the addition of sodium chloride or similar materials.
Centrifuge to separate aqueous phase.
After the oxidation and the separation from the aqueous phase(H2O2), the sulfones can be extracted using a polar solvent, such as acetonitrile at the second stage.
A sugar content of at least 62.5% in the aqueous phase is required.
The bitumen is dispersed throughout the continuous aqueous phase in the form of discrete droplets, typically 0.5 to 5 microns in diameter, which are held in suspension by electrostatic charges.
The addition of surfactant facilitates the dispersion of asphalt particles in the aqueous phase(water) and keeps it dispersed in suspension.
When the organosulfur compounds react at a phase boundary, the sulfoxides and sulfones accumulate at the aqueous droplet surface andblock other sulfur compounds from interacting at aqueous phase.
In there,ultrasonic cavitation produces high hydraulic shear and breaks the aqueous phase into sub-micron and nanosize droplets.
The oil phase and the aqueous phase are mixed are pumped into a static mixer to produce a basic emulsion of a constant volumetric ratio that is then fed to the ultrasonic mixing reactor.
By using a phase transfer catalyst, it becomes possible to solubilize ionic reactants,which are often soluble in an aqueous phase but insoluble in an organic phase. .
Immediately after sonication, the emulsion is poured into the aqueous phase(0.1% PVA in water; 200mL) for diffusion under rapid stirring with a magnetic stirrer.
An additional benefit of the ultrasonic TPP is the enhanced activity of various enzymes, resulting in apparent higher yields(gt;100%) since the targeted enzyme orprotein precipitates out in the middle layer between the organic and aqueous phases.
At this stage, the insolubility of the polar aqueous phase and the nonpolar organic phase is a significant problem in the process of oxidative desulfurization as both phases react with each other only at the interphase.
Whilst pigments, lipids and enzyme inhibitors accumulate in the upper solvent phase, which is separated from the lower aqueous phase, where polar components like saccharides are accumulated, by an intermediate protein precipitated layer.
The protein is composed mainly of proteins which include ovoalbumin, ovokonalbumin, ovoglobulin, lysozyme and OE These proteins are responsible for such functionalproperties of the protein in the production of mayonnaises as solubility in the aqueous phase, the ability to disperse and bactericidal action(lysozyme).
It was found that the heterogeneous liquid-liquid phase saponification of different vegetable oils using aqueous KOH/CTAB was significantly accelerated at 35ºC under sonication and stirring.
It reacts with aqueous sodium hydroxide usually in the presence of a phase transfer catalyst to produce dichlorocarbene, CCl2.
Butter is an aqueous emulsion in milk-fat, the water being its dispersed phase and the fat its dispersion medium.
Amphiphilic emulsion catalysts or phase-transfer catalysts(PTC),such as quaternary ammonium salts with their unique capability to dissolve in both aqueous and organic liquids have been shown to incorporate with the oxidant and transport it from the interface phase to the reaction phase, thereby enhancing the reaction rate.
The phase-transfer reagent helps to promote the heterogeneous reaction between the aqueous and oil phases, which is the rate-limiting step of the ODS reaction.
Surface boiling" with the salt effect as anew kind of the transition of salts in the gas phase from aqueous solutions.
If the sample is soluble, the solute(such as sucralose, salts, e.g. in powder or tablet form)can be dissolved in a solvent(e.g. water, aqueous solvents, organic solvents etc.) resulting in a homogeneous mixture, composed of only one phase. The dissolving process can be carried out by manual or mechanical stirring, which is time-consuming and inefficient.
