Introduction: Extraction is the most widely used method for the separation of an organic product from its reaction mixture or for the isolation of naturally occurring substances. It is a separation technique based on differences in solubility of substances in two immiscible solvents (organic solvent and aqueous solution), and it has a partition coefficient (Kc) equals to the solubility in solvent 1 divided by the solubility in solvent 2. There are two types of extraction: simple and multiple extractions. Multiple extractions with smaller amounts of solvent are more efficient than a single extraction with the same total amount of solvent. The purpose of this experiment was to show the basic principles of this very important technique. Divided into two parts, the experiment demonstrated the greater effectiveness of

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
