Abstract: In this experiment, a thin-layer chromatography (TLC) was used to determine the composition of various over-the-counter analgesics. (ACETAMINOPHEN, Acetylsalicylic Acid, Caffeine, and ibuprofen). Chromatography is a technique that we used to separate and identify individual components in a mixture. …
Starting, Material, serves also as the solvent colorless liquid with a smell of acetic acid Molar Mass: 102. 09 g/mol Melting Point: -73. 1 0C Boiling Point: 139. 8 0C Density: 1. 082g/cm3 Corrosive Flammable and Lachrymator which makes eyes …
Once the aspirin is prepared, it is isolated from the reaction solution and then it is purified. The aspirin is insoluble in cold water, and it is isolated by filtering the chilled reaction solution. Purification is essential to remove any …
I. SynopsisThe synthesis of aspirin is known in organic chemistry as an esterification reaction. In this experiment, preparation of aspirin were conducted and followed by recrystallisation to have it purified. Aspirin was prepared from salicylic acid and acetic anhydride. Concentrated …
The mechanisms actions of non-steroidal anti-inflammatory drugs (NSAIDs) To summarise, non-steroidal anti-inflammatory drugs are drugs which have anti-inflammatory, analgesic and antipyretic properties due to their mechanism and enzymes involved COX-1 and COX-2. However as well as being beneficial NSAIDs have …
Discussion: The goal of this experiment was to use TLC Analysis to determine the analgesic drug present in the unknown solution 154. One observation of the unknown spotting solution was that it was cloudy. After forming the unknown spotting solution …
