Supercritical fluid extraction - Wikipedia

Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent.Extraction is usually from a solid matrix, but can also be from liquids.SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product (e.g ...

Extraction - University of Pittsburgh

The three most common types of extractions are: liquid/liquid, liquid/solid, and acid/base (also known as a chemically active extraction). The coffee and tea examples are both of the liquid/solid type in which a compound (caffeine) is isolated from a solid mixture by using a liquid extraction solvent (water).

Specific topics include chemistry of metal solvent extraction, the novel competitive complexation/solvation theory (CCST) of solvent extraction, CCST in the solvent extraction of acids by amine-based extractants, modern and future trends in fundamentals, and developments of solvents for liquid-liquid extraction.

Definition of extraction - Chemistry Dictionary

Easy Example of Extraction Tea-making is a very basic non-laboratory extraction. You boil tea leaves in water to extract the tannins, theobromine, polyphenols, and caffeine out of the solid tea leaves and into the liquid water. You are then free to drink and enjoy the water and the extracted substances it contains. Laboratory Extractions

LIQUID LIQUID EXTRACTION - stscanadainc.com

Liquid Liquid Extraction. Liquid–liquid extraction (LLE) also known as solvent extraction, is a method to separate compounds based on their relative solubility in two different immiscible liquids, usually water and an organic solvent.. It consists of transferring one (or more) solute(s) contained in a feed solution to another immiscible liquid (solvent).

The Complete Guide to Hydrocarbon Extraction [New in 2019]

Sep 19, 2019·Liquid-liquid Extraction. Organic compounds are often extracted from aqueous solutions using a separatory funnel and a hydrocarbon solvent such as hexane; this technique is referred to as liquid-liquid extraction. Solid-liquid Extraction. Solid-liquid extractions are often used to extract natural compounds from natural sources, such as plants [1].

Extraction - Solvent Selection

The solvent is the key to a successful separation by liquid-liquid extraction. The several criteria are: 1. Distribution Coefficient. This is the ratio (at equilibrium) of the concentration of solute in the extract and raffinate phases. It gives a measure of the affinity of the solute for the two phases.

Raw materials that are suitable for extraction may contain either solids only, solids and a solution, or solids and a liquid. Solid/liquid extraction is sometimes called leaching. When the soluble component is incorporated in a liquid, liquid/liquid extraction may be applied to …

Methods of Extraction for Vegetable (Carrier) Oils

Carbon dioxide is converted to liquid using high pressure making it a safe and effective solvent that allows all the desirable active constituents of a plant to be collected without the risk of heat degradation. Once the extraction is complete, the pressure is released allowing the carbon dioxide to return to its natural gaseous state, leaving ...
