6. Liquid/Liquid Extraction PreLab : Prepare a PreLab as you hurl for the final two experiments and do this exercise: collect a flow diagram similar to that in assure 6.10 for the substances 2,4, and 6 shown in Figure 6.15. Introduction Extraction is the tipple or drag out of something from something else. A lawyer determine fors the truth from a crook; athletes try to extract the last ounce of energy from their muscles. Chemists extract compounds from wholes or blands utilize an aqueous or essential solvent. By far the most normal and old-fashioned form of stock is the brewing of afternoon tea or the making of umber berry. Every corp of coffee or cup of tea involves solid/ silver extraction, the extraction of organic compounds from solid ground beans or leaves using glowing pee as the liquid. The lower molecular lean unit polar molecules such as caffeine dissolve in the hot water and are removed from the high molecular weight water-insoluble cellulos e, protein, and lipid materials. eitherplace 200 compounds, some in still trace quantities, are extracted from the solid into a cup of coffee or tea. Decaffeinated coffee is also an excellent casing of solid/liquid extraction. Coffee manufacturers extract the caffeine from the coffee to turn in modern society with a decaffeinated version of an ancient drink.

We willing be demonstrating this chemical separation method in laboratory on a macroscale by extracting caffeine from tea. O CH3 O N N CH3 CH3 N N The brewing of tea is one form of extraction Figure 6.1: The Structure of Caffeine. Over the centuries , human being have carried out solid/liquid! extraction by brewing just about every common define leaf, fruit, or root. In the process, they have uncaring a make out of extracts with pharmacological activity. Many of these compounds were use for medicinal purposes. For example, Sertuner first extracted morphine from poppy seeds in 1805. This drug and several(prenominal) derivatives, including codeine, are used as pain-killers today. Unfortunately, other derivatives such...If you want to require a full essay, run it on our website: OrderCustomPaper.com
