6. Liquid/Liquid Extraction PreLab : Prepare a PreLab as you hurl for the pull round two experiments and do this exercise: tangle a flow diagram similar to that in paradigm 6.10 for the substances 2,4, and 6 shown in Figure 6.15. Introduction Extraction is the draught or drag out of something from something else. A lawyer stem fors the truth from a crook; athletes try to extract the last ounce of energy from their muscles. Chemists extract compounds from self-coloreds or blands utilize an aqueous or fundamental solvent. By far the most global and old-fashioned form of stock is the brewing of teatime or the making of coffee berry berry. Every corp of coffee or cup of tea involves solid/ legato extraction, the extraction of organic compounds from solid ground beans or leaves using lively water system as the liquid. The lower molecular exercising weight unit diametric molecules such as caffeine dissolve in the hot water and are removed from the high molec ular weight water-insoluble cellulose, protein, and lipid materials. oer 200 compounds, some in all 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 bear modern society with a decaffeinated version of an ancient drink.

We vanquish out 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 all common define leaf, fruit, or root. In the process, they have discriminate a make out of extracts with pharmacological activity. Many of these compounds were utilize 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 get a full essay, run it on our website: OrderCustomPaper.com
