inquiry 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 . Solvent extraction is used in the processing of perfumes, vegetable oil, or biodiesel.
inquiry MeTHF is the way to go for a lot of things. It splits with water (well…a dilute brine helps with that split). It's a stronger extracting solvent than ether. You can get to most other useful solvents from it through distillation. Can do all the same reactions as ether, with a significantly lower peroxide risk. It has a decent water azeotrope.
