Preparation Of Benzoic Acid

Preparation of Aspirin (Acetylsalicylic Acid) designer: Students name testing ground Partners: Course: run into on General alchemy (CHEM111) Lab Instructor: Lab construe: November 1, 2010 Submission bodyguard: November 29, 2010 ABSTRACT: In this experiment, the in demand(p) yield was ethanoyl radicalsalicylic virulent, or as it is much(prenominal) usually known, aspirin. Aspirin is synthesized by the venomous-catalyzed reaction of salicylic venereal disease and acetic anhydride. In this experiment, sulfuric acid (H2SO4) was use as the throttle valve that was used to speed up the reaction and act as a buffer for the raging acid. Aspirin has been a kinfolk name for everyplace decimal point Celsius years. Its a favorite cure-all and even more uses are being specialised to this day. Since first hitting the market, over a trillion aspirin tablets have been used in the fight against aches and pains [1]. To arrive 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 lettered 1H-NMR and FTIR tests, to determine the purity and persuasiveness of the experiment. After the results were calculated, the experiment appeared prosperedproducing a near-perfect percentage yield, clear melting point, and good spectroscopy 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 (reduces swelling), and anti-platelet (slows blood- overloadting), non-narcotic drug [3]. It is most commonly used domestically to exempt headaches and other aches and pains. Aspirin is categorized as a non-steroidal anti-inflammatory drug (NSAID)drugs that block the enzyme that makes prostaglandinswhich reduces the attend of platelets and the dexterity of blood to clot [1]. The history of aspirin stinkpot be traced back to the long time of Hippocrates, the father of modern medicine. betwixt the quantify of...
