Web2 apr. 2024 · The purification of organic compounds is an essential component of routine synthetic operations. The ability to remove contaminants into an aqueous layer by generating a charged structure provides an opportunity to use extraction as a simple purification technique. WebThere are two major types of extractions used in the organic laboratory being, liquid-liquid and solid-liquid extractions. The process of a solid-liquid extraction occurs when a compound is extracted from a solid material into a liquid, and when the transfer occurs from one liquid into another, it is called a liquid-liquid extraction.
