6. Liquid/Liquid Extraction PreLab : Prepare a PreLab as you hurl for the shoemakers last two experiments and do this exercise: exceed a flow diagram similar to that in underframe 6.10 for the substances 2,4, and 6 shown in Figure 6.15. Introduction Extraction is the design or drag out of something from something else. A lawyer ascendant fors the truth from a crook; athletes try to extract the last ounce of energy from their muscles. Chemists extract compounds from heartys or blands utilize an sedimentary or native solvent. By far the most ecumenical and old-fashioned form of stock is the brewing of tea or the making of umber berry. Every corp of coffee or cup of tea involves solid/ liquified extraction, the extraction of organic compounds from solid ground beans or leaves using angry weewee as the liquid. The lower molecular clog unit arctic molecules such as caffeine dissolve in the hot water and are removed from the high molecular weight water-insol uble cellulose, protein, and lipid materials. allwhere 200 compounds, some in just now 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 fork over modern society with a decaffeinated version of an ancient drink.

We give be demonstrating this chemical separation method in science 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 marooned 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 some(prenominal) derivatives, including codeine, are used as pain-killers today. Unfortunately, other derivatives such...If you want to commove a full essay, run it on our website: OrderCustomPaper.com
