WebApr 4, 2024 · Immiscible solvents, those that do not mix, are used in the chemical process of liquid/liquid extraction, where compounds of interest may be separated by taking advantage of their different solubilities in water and a lipophilic solvent. For example, if a mixture of vitamin C, which is highly water soluble, and vitamin E, which is fat-soluble, is shaken with … WebA competitive monoclonal antibody-based immunoassay which quantifies a hydrophobic hapten (Rx) in water immiscible solvents, obviating the need of a pre-extraction step, has …
WebJul 1, 2009 · Liquid–liquid extraction (LLE), also known as solvent extraction, has long been an effective method of separating compounds having different solubilities in two immiscible liquids (1). The two liquids are typically water, perhaps with some additives, and a nonpolar organic solvent such as isooctane. Typically, polar compounds prefer the ... WebThe solvent must have the following properties: i. The solvent must be able to dissolve the organic solutes in a relatively small volume. The solvent must be immiscible with water. The solvent must not react with the organic solutes or the aqueous reagent. iv. The solvent must be able to easily removed from the solute at the end of the procedure.
