Lab 3 no name

1800’s. Salicylic acid derived from the willow tree’s bark was the key chemical involved with the relief of pain and the reaction to make aspirin is a fairly simple one performed in numerous chemistry classroom nation wide.  Aspirin can be made by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4). C4H6O3  + C7H6O3 --> C2H4O2­  + C9H8O4 When synthesizing aspirin, a student began with 3.20 mL of acetic anhydride (density  = 1.08 g/mL) and 1.45 g of salicylic acid...

Aspirin and Its Therapeutic Uses

not depend entirely on the invention and introduction of new medicine! Aspirin, also known as acetylsalicylic acid, is a salicylate drug, often used as an analgesic to relieve minor aches and pains, as and antipyretic to reduce fever, and as an anti-inflammatory medication. Aspirin was first isolated by Felix Hoffmann, a chemist with the German company Bayer in 1897. Acetylsalicylic acid (ASA) decomposes rapidly in solutions of ammonium acetate or of the acetates, carbonates, citrates or hydroxides...

Organic Chem experience 11

Introduction Methyl Salicylate has been used for a long time for its pleasant odour and flavour. The objective of this experiment was to carry an organic synthesis; the preparation of salicylic acid from methyl salicylate. To do an organic synthesis, it is needed to chemically modify the molecules of another compound to end up with the desire compound. Methyl salicylate is the major constituent of wintergreen oil, which is why it was used in this experiment as the starting material. The new technique...

Lab on Aspirin Tablets

____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First, the base was created, which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that, one by one, an aspirin tablet was dropped...

Synthesis of Salicylic Acid from Wintergreen Oil

Introduction This lab's purpose was to determine whether Salicylic Acid made from methyl salicylate is the same as Salicylic Acid made from benzene. This information can be found by comparing the difference in melting points of the two samples of Salicylic Acid. Here are the physical properties of Salicylic Acid and the mechanism of reactions that occurred in this lab. How Salicylic Acid is derived: Procedure/Results First, .26mL of 2.0mmol methyl Salicylate was measured and put...
