Lab Report #7 Preparation of Acetylsalicylic Acid Karen McClellan designation: Synthesis of aspirin The manipulation of this experiment is to explore how chemical sum reactions occur by synthesizing acetylsalicylic acid and then analyzing the aspirin for fidelity and yield. Aspirin is the most wide used over-the-counter dose in the world. The average launch area contains about 325 milligrams of acetylsalicylic windowpane glass with an inert binding material such(prenominal) as starch. Aspirin is used to relieve pain, reduce inflammation, and sink fever. Aspirin production line eithery was derived by boiling the bark of the uncontaminating willow tree. Although the salicin in willow bark has analgesic properties, purified salicylic acetous was bitter and nominate at when taken orally. Salicylic acid was neutralized with sodium to produce sodium salicylate, which was better-tasting but still irritated the stomach. Salicylic acid could be circumscribed to produce phenylsalicylate, which was better tasting and less(prenominal) irritating, but released the toxic substance phenol when metabolized. By law, all medicines sold in the linked States must(prenominal) meet purity standards set by the fare and Drug Administration, so all aspirin is essentially the same. each(prenominal) 5 grain tablet contains 0.325 g of acetylsalicylic acid held unneurotic with a binder.
The remarkable difference in price for aspirin is primarily a reflection of the publicise budget of the corporation that sells it. Aspirin is an analgesic (painkiller), an antipyretic (fever reducer), and an anti-inflammatory agent. It is the chanc! ellor drug for reducing fever, a role for which it is uniquely suited. As an antiinflammatory, it has execute the most widely effective treatment for arthritis. Patients scummy from arthritis must take so much aspirin (up to tetrad grams per day) that stomachic problems may result. For this reason, aspirin is often combined with a buffering agent. buffered aspirin is an example of such a preparation. The ability of aspirin to decrease inflammation is apparently due to its inhibition of the...If you command to get a full essay, order it on our website: BestEssayCheap.com
