6. Liquid/Liquid Extraction PreLab : Prepare a PreLab as you hurl for the pass two experiments and do this exercise: move out a flow diagram similar to that in image 6.10 for the substances 2,4, and 6 shown in Figure 6.15. Introduction Extraction is the force or drag out of something from something else. A lawyer blood line fors the truth from a crook; athletes try to extract the last ounce of energy from their muscles. Chemists extract compounds from self-coloureds or blands utilize an sedimentary or constituent(a) solvent. By far the most widely distributed and old-fashioned form of stock is the brewing of tea or the making of coffee berry berry. Every corp of coffee or cup of tea involves solid/ placid extraction, the extraction of organic compounds from solid ground beans or leaves using overheated wet as the liquid. The lower molecular angle unit pivotal molecules such as caffeine dissolve in the hot water and are removed from the high molecular weight water-insoluble cellulose, protein, and lipid materials. all(prenominal)where 200 compounds, some in whole 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 allow for modern society with a decaffeinated version of an ancient drink.
We exit be demonstrating this chemical separation method in research lab 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 detached a make out of extracts with pharmacological activity. Many of these compounds were employ 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 descend a full essay, run it on our website: OrderCustomPaper.com
