Sentences Containing 'solvent'
The real activity of ground water is due to its great solvent power; every time we put sugar into tea or soap into water we are using water as a solvent.
The opinion of all the commercial men was that, under the reverses which had successively weighed down Morrel, it was impossible for him to remain solvent.
``Is it possible that Thomson&French are not looked upon as safe and solvent bankers?
``Thomson&French are perfectly solvent,''replied Danglars, with an almost mocking smile:``but the word unlimited, in financial affairs, is so extremely vague.''
Furthermore, solvent concentration during polymerization affects both of these factors.
Eventually, increasing solvent concentration creates a surface prone to fouling.
In industrial paper-making processes, organosolv is a pulping technique that uses an organic solvent to solubilise lignin and hemicellulose.
The concentration of solvent in water ranges from 40-80%.
This is weighed against the more difficult solvent recovery by distillation.
Ethanol has been suggested as the preferred solvent due to cost and easy recovery.
Although butanol is shown to remove more lignin than other solvents and solvent recovery is simplified due to immiscibility in water, its high cost limits its use.
The Alcohol Pulping and Recovery (APR) process treats wood in 3 stages, each using increasingly cleaner solvent.
The important process parameters are extraction time, temperature, solvent composition and pH.
once used methylene chloride, an animal carcinogen on the United States Environmental Protection Agency's list of pollutants, as a solvent in some of its manufacturing processes.
This way, a centrifugal extractor generates a continuous extraction from one liquid phase (fermentation broth) into another liquid phase (organic solvent).
It has been employed in solvent extraction processes for metals valuable to the nuclear industry.
The successive mixing and separation operations performed in each mechanical stage permit the mass transfer of the solutes from the feed solution to the solvent.
One particularly important example for public health is the organochloride respiration of the dry-cleaning solvent, tetrachloroethylene (PCE), and the engine degreasing solvent trichloroethylene (TCE) by naturally occurring anaerobic bacteria, often members of the candidate genera "Dehalococcoides".
It is essential that the amount of solvent being used be limited to less than what would overflow the flask, otherwise the solvent will be drawn into the vacuum equipment.
If the vacuum is provided by a water flow device, an overflow of the solvent could result in the spilling of a hazardous solvent into the wastewater stream, a potential violation of the law, depending on the solvent.
However, it is often the case that further drying is required, by an oven or other means, in order to remove as much residual solvent as possible.
One that shows the most promise is the use of hexane as a solvent.
After this extraction process soluble proteins will be in the solvent, and can be separated from cell membranes, DNA etc. by centrifugation.
Consequentially, proteins of a certain range in size will require a variable volume of eluent (solvent) before being collected at the other end of the column of gel.
The proteins are eluted by a gradient of increasing amounts of an organic solvent, such as acetonitrile.
Here a coal extract was prepared under heat and hydrogen pressure using finely pulverized coal and recycle donor solvent.
As the coal molecule is broken down, free radicals are formed which are immediately stabilized by absorption of H atoms from the donor solvent.
Typical species in the donor solvent are fused-ring aromatics (tetrahydronaphthalene and up) or the analogous heterocycles.
the maximum concentrations achieved are the points at which the van der Waals forces overcome the interactive forces between the graphene sheets and the solvent molecules.
Similar to solvent exfoliation, graphite is sonicated in a suitable solvent.
The concentration of graphene achieved by this method is higher than solvent exfoliation, but the removal of the surfactant molecules is often necessary and usually requires chemical treatments.
Dispersal.
