Some articles on solvent extraction, extraction, solvents, solvent:

Fragrance Extraction - Maceration/Solvent Extraction - Ethanol Extraction
... Ethanol extraction is a type of solvent extraction used to extract fragrant compounds directly from dry raw materials, as well as the impure oils or concrete resulting from organic solvent extraction ... The impure substances or oils are mixed with ethanol, which is less hydrophobic than solvents used for organic extraction, dissolves more of the oxidized aromatic constituents (alcohols ... processed to remove any impurities that are still present from the solvent extraction ...
Molecular Imprinted Polymer - Template Removal - Solvent Extraction
... Soxhlet Extraction This has been a standard extraction method with organic solvents since its creation over a century ago ... consists of placing the MIP particles into a cartridge inside the extraction chamber, and the extraction solvent in poured into a flask connected to the ... The solvent is then heated and condenses inside the cartridge thereby contacting the MIP particles and extracting the template ...
Perfume - Obtaining Natural Odorants
... The results of the extraction are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product ... This is due to the use of heat, harsh solvents, or through exposure to oxygen in the extraction process which will denature the aromatic compounds, which either change their odor character or renders ... Maceration/Solvent extraction The most used and economically important technique for extracting aromatics in the modern perfume industry ...
Two-phase Liquid Extraction
... Liquid–liquid extraction also known as solvent extraction and partitioning, is a method to separate compounds based on their relative solubilities in two different immiscible liquids ... It is an extraction of a substance from one liquid into another liquid phase ... Liquid–liquid extraction is a basic technique in chemical laboratories, where it is performed using a separatory funnel ...
Perfume - Fragrant Extracts
... have been extracted from raw materials through solvent extraction using volatile hydrocarbons ... Concretes usually contain a large amount of wax due to the ease in which the solvents dissolve various hydrophobic compounds ... further purified through distillation or ethanol based solvent extraction ...

Famous quotes containing the words extraction and/or solvent:

    Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems.
    Rudolf Carnap (1891–1970)

    Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.
    Thomas Mann (1875–1955)
