The solution is then refluxed which means that the solution will be boiled in a base, then condensed in a condenser. This preview shows page 4 out of 4 pages. Summary: Suveda Perikala Aspirin originated from the bark of a White Willow Tree. The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. Forty million pounds are produced each year. Experiment #5 In this case, an acetyl group was added to salicylic acid, a naturally occurring compound with significant pharmaceutical value.

This question is too broad, because it depends on the procedure you used, and also whether you're talking about the reaction itself or the recrystallation. Lab 1: Synthesis of Aspirin Aspirin Synthesis Lab Report – A laboratory report is essentially how you describe what you’ve done in a laboratory experiment, what you discovered, and the results. We will be taking salicylic acid, acetic anhydride, and phosphoric acid and using them to create aspirin. Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon, hydrogen and oxygen. Course Hero is not sponsored or endorsed by any college or university. What you mean is "reduced yield" or "loss of material" or "incorporation of impurities" or something like that, whatever it is that you actually mean. crystallization, recrystallization, and melting point determination. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). This, could have occurred when stirring the salicylic acid, acetic anhydride, and phosphoric, acid in the Erlenmeyer flask, which was sitting in boiling water. The main purpose of this lab is to obtain aspirin through the chemical synthesis of salicylic acid by acetylation with acetic anhydride and crystallization. Myocardial infarction, Acetic acid, Platelet 973 Words | The use of aspirin had its origin in the 18 th century, when it was found that an A. Quiñones Share. A second group was also used to compare results and errors, in which they too were also producing extremely low percent yields of Tylenol. University of North Texas. Acetic anhydride, Sulfuric acid, Vinegar 1712 Words | In the 5th century B.C., Hippocrates ground the bark into a powder, and later, the Natives Americans chewed on the bark to alleviate fever and pain1. In this case, an acetyl group was added to salicylic acid, a naturally occurring compound with significant pharmaceutical value. 7/1/14 5 Pages.
