Preparation Of Benzoic Acid

Preparation of Aspirin (Acetylsalicylic Acid) reservoir: Students name research laboratory Partners: Course: contact on General chemical science (CHEM111) Lab Instructor: Lab construe: November 1, 2010 Submission particular date: November 29, 2010 ABSTRACT: In this experiment, the desire yield was acetyl groupsalicylic virulent, or as it is much(prenominal) ordinarily known, acetylsalicylic sulphurous. Aspirin is synthesized by the point-catalyzed reaction of salicylic acid and acetic anhydride. In this experiment, sulfuric acid (H2SO4) was use as the throttle that was used to speed up the reaction and act as a buffer for the tumefy acid. Aspirin has been a dwelling house name for everyplace class Celsius years. Its a touristy cure-all and even more uses are being specialise to this day. Since first hitting the market, everywhere a trillion aspirin tablets have been used in the fight against aches and pains [1]. To enkindle this wonder drug, we reacted salicylic acid with acetic anhydride, which resulted in the desired acetylsalicylic acid and acetic acid. The product was go down through a series of tests, including newly intimate 1H-NMR and FTIR tests, to determine the purity and military strength of the experiment. After the results were calculated, the experiment appeared sure-fireproducing a near-perfect percentage yield, good melting point, and good spectroscopic analysis results.

incoming: Aspirin, or acetylsalicylic acid, is an acetyl derivative of salicylic acid that is a efficacious analgesic (pain reliever), anti-pyretic (reduces fever), anti-inflammatory drug (reduces swelling), and anti-platelet (slows blood- back upting), non-narcotic drug [3]. It is most commonly used domestically to soothe headaches and other aches and pains. Aspirin is reason as a non-steroidal anti-inflammatory drug (NSAID)drugs that block the enzyme that makes prostaglandinswhich reduces the situation of platelets and the dexterity of blood to clot [1]. The history of aspirin net be traced back to the geezerhood of Hippocrates, the father of modern medicine. in the midst of the quantify of...
