Liquid extraction

All unapproved Citizendium articles may contain errors of fact, bias, grammar etc. A version of an article is unapproved unless it is marked as citable with a dedicated green template at the top of the page, as in this version of the 'Biology' article. Citable articles are intended to be of reasonably high quality. The participants in the Citizendium project make no representations about the reliability of Citizendium articles or, generally, their suitability for any purpose. This article is currently being developed as part of an Eduzendium student project in the framework of a course entitled BEE 4640 Bioseparation Processes at Cornell University. The course homepage can be found at CZ:Cornell_University_2010_BEE_4640_Bioseparation_Processes. For the course duration, the article is closed to outside editing. Of course you can always leave comments on the discussion page. The anticipated date of course completion is 21 December 2010. One month after that date at the latest, this notice shall be removed. Besides, many other Citizendium articles welcome your collaboration! Note to course participants: Looking forward to some insightful and useful articles from your collaborations.

The following list of sections may serve as a loose guideline for developing the body of your article. Before deciding to follow it, take a look at some other articles on subjects like your own. You may like their structure better and if so, adopt it.

The works cited in references 2-5 are all fake (and are borrowed from another Eduzendium template); their purpose is to serve as a formatting model for your own citations.

Extraction

Solvent Extraction is a process that separates components in a matrix by contact with another liquid. Typical extractions include, liquid-solid extractions, liquid-liquid extractions and Supercritical extractions. Separation is based on the compounds’ physical and chemical properties. Extraction is well used within the perfume industry to separate aromatic compounds from hydrocarbon mixtures in petrochemical operations using high boiling polar solvents.

History

Solvent extraction is an old practice done for years. It is the main process in perfume development and it is also used to obtain dyes from various sources.

Modern use has made this process an essential practice in scientific laboratories. in 1872 Berthelot and Jungfleisch introduced the concept of the partition coefficient. Followed by an introduction in phase equilibrium by Gibbs. Many of these advances occurred as the chemical industry grew as well.

Further research and improvements to the process affected the commercial applications. Due to the advantages of solvent extraction various chemical treatment methods for refining coal tar products and mineral oil were replaced.

Design and Operation

Use lots of subsections here as you describe various aspects of the process .

Applications

This section should discuss how the process is used in practice.

Examples

If you have used a lot of equations in your article, this may be a good place to show an example of how they are used. See the article on the Antoine Equation for an example.
