Soxhlet extractor - Wikipedia
A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently ...

Solvent Extraction - AOCS Lipid Library
Solvent Extraction Background. One of the most basic needs of mankind is an abundant and reliable food supply. In the modern world, one major source of protein and vegetable oil is from oilseeds, particularly the soybean – an abundant resource which is largely processed using solvent extraction, an efficient and reliable means to separate the high-protein meal solids from the high-energy ...
Different extraction methods of biologically active ...
In all three extraction techniques the amount of solvent used (10:1 or 20:1) does not significantly influence the extraction yield (ANOVA). This is an important finding because it demonstrates that the use of solvent/propolis ratios larger than 10:1 (v/w) is unnecessary, leading only to solvent …
Solvent extraction | chemistry | Britannica.com
Solvent extraction processes are employed primarily for the removal of constituents that would have an adverse effect on the performance of the product in use. An important application is the removal of heavy aromatic compounds from lubricating oils.
Solvent extraction - Simple English Wikipedia, the free ...
Solvent extraction, also known as Liquid–liquid extraction or partitioning, is a method to separate a compound based on the solubility of its parts. This is done using two liquids that don't mix, for example water and an organic solvent.
Extraction Theory and General Procedure - Wellesley College
Extraction is a very common laboratory procedure used when isolating or purifying a product. Organic chemistry employs solid-liquid, liquid-liquid, and acid-base extractions. The following applies to liquid-liquid extractions, which will be used in this course.
Liquid–liquid extraction - Wikipedia
Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another ...
