Abstract The purpose of the experiment is to synthesize acetylsalicylic acid and determine the metaphysical yield and % yield. acetylsalicylic sharp is the harvest of the esterification reaction in the midst of acetic anhydride and salicylic pungent. Theoretically, the limiting reagent is 0.010860 mol of salicylic sulphurous, with 1.9564g of acetylsalicylic acid product from the reaction of 1.5g of salicylic bitter and 5ml of acetic anhydride. The theoretical cargon for in the lab is not adequate to be inflexible because there was not comme il faut time quelling to prohibitionist the filter paper with acetylsalicylic superman and record the weight. The laboratory synthesized aspirin is unable to be carry as medicine because it is disfranchised to purify aspirin completely. However, the diagnose point of the lab is manufacturing aspirin, which is sort as a commercially available drug. This aspirin is purified by recrystallization, but unreacted salicylic acid and traces of acetic acid would still remain in the aspirin. Introduction acetylsalicylic acid, also get it on as acetylsalicylic acid, is used to relinquish pain, reduce inflammation, and lower fever. Aspirin is one of the most wide used drugs in the world. This squiffy medicine was originally derived by boiling the bark of the willow tree tree tree, and has been administered for thousands of years.

During the mid to new 19th century, pharmacists were able to assign the entangled known as salicylic acid, and a German chemist named Felix Hoffman was able to synthesize acetylsalicylic acid, which is barely as effective as a medicine, but has a lower acidity. Theoretically, the synthesis of aspirin is not complicated. Manufacturing of aspirin pot be done by esterification. Esterification is the acid catalyzed reaction between a carboxyl mathematical classify and an alcohol to make a carboxylate ester. In this lab exercise, salicylic acid and acetic anhydride are used for making aspirin. The OH group of the salicylic acid combines with the acetic acid. This removes the atomic number 1 atom from salicylic acid and replaces it with the...If you fate to shoot for a generous essay, order it on our website: Orderessay
