Aspirin synthesis and analysis experiment 9 in beran page 119 to 126 prelab = page 123-124, all questions post lab, page 126 all questions • the synthesis of aspirin is an esterification reaction • esterification is the general name for a chemical reaction in which two chemicals (typically an. In this experiment, you will prepare aspirin from salicylic acid and acetic anhydride using sulfuric acid as a catalyst you will determine the percent yield of aspirin and you will confirm it's identity with ft-ir spectroscopic anaylsis. In this experiment, you will prepare aspirin from salicylic acid and acetic anhydride using sulfuric acid as a catalyst you will determine the percent yield of aspirin and you will confirm it's identity with ft-ir spectroscopic anaylsis the purity of the sample will be qualitatively determined with melting point analysis.
Synthesis and spectral analysis of aspirin synthesis of aspirin learning goals 1 to synthesize aspirin from salicylic acid and acetic anhydride 2 to purify the crude product by recrystallization introduction most drugs are chemical compounds which are described as organic compounds because they are comprised primarily of the elements carbon, hydrogen and oxygen.
After aspirin synthesis was complete, the aspirin was analyzed using both ir and nmr spectrometers in order to determine the hydrogen atoms and organic functional groups present in the synthesized aspirin and to verify the overall identity of the aspirin.
Los angeles city college chemistry 51 fall 2005 3093 1 experiment 11 synthesis and analysis of aspirin introduction aspirin is most widely sold over-the-counter drug it has the ability to reduce fever (an antipyretic), to. Start studying experiment 34: synthesis and spectral analysis of aspirin learn vocabulary, terms, and more with flashcards, games, and other study tools. Experimental synthesis of aspirin and melting point purity analysis donald yeargin ch 222, section 24221 department of chemistry portland community college portland, or abstract the various methods available to synthesize aspirin lead to the need to examine and evaluate production efficiency and purity. The synthesis and analysis of aspirin aspirin, the ubiquitous pain reliever, goes by the chemical name acetylsalicylic acid one of the compounds used in the synthesis of aspirin is salicylic acid, which is itself a pain reliever that was known to many ancient cultures, including the native americans who extracted it from willow tree bark.
The analysis of the aspirin is done by taking the ir and the nmr along with the melting points and a ferric chloride test on both crude and pure products history analgestics are drugs used to treat pain while antipyretics are used to reduce fevers such drugs that do both of these include aspirin, tylenol, and ibuprofen.
A student researched lab analysis about the synthesis and characterization of aspirin by measuring the melting point as well as taking a uv spectroscopy. Synthesis and analysis of aspirin 15 quantitatively prepare the stock salicylic acid solution a measure out about 020 g of salicylic acid record the precise mass that you use b transfer the salicylic acid to a 250 ml beaker and add 10 ml of 95% ethanol swirl the beaker to dissolve the solid c add 150 ml of distilled water to the beaker.
