Ethanol Extraction vs. CO2 Extraction What Is The Best
The organic solvent used for extraction must meet a few criteria: Should readily dissolve substance to be extracted. Should not react with the substance to be extracted. Should not react with or be miscible with water (the usual second solvent). Should have a low boiling point so it can be easily removed from the product. Common extraction solvents are diethyl ether and methylene chloride...

To determine which of the soxhlet extraction with ether, or the solvent extraction with a 3:2 mixture of hexane/isopropanol was more efficient, the percent fat extracted in terms of mass was used to compare the two methods. This was done by creating a sample with a known mass of oil in it, and comparing the mass of the sample before extraction with its mass after the oil had been extracted

How To Choose A Solvent For Extraction

The key to successful extraction is, firstly to choose a solvent with an affinity for the product to be separated, and secondly to provide equipment for the extraction which promotes an intimate contact between the feed liquor and solvent. The efficiency of extraction is then determined by the difference in solubility of the product of interest between the two solvents and the efficiency of
