Aspirin, also known as acetylsalicylic acid, is a common over-the-counter pain reliever and anti-inflammatory medication. It is used to treat a variety of ailments, including headaches, muscle pain, and fever. Aspirin is synthesized through a chemical reaction known as esterification, which involves the combination of a carboxylic acid and an alcohol. The synthesis of aspirin involves the following equation:

Reactants:

Products:

The synthesis of aspirin begins with the reactant salicylic acid, which is derived from plants such as willow trees and meadowsweet. Salicylic acid is a natural compound that has been used for centuries to treat a variety of ailments, including pain and inflammation.

Next, the reactant acetic anhydride is added to the salicylic acid. Acetic anhydride is a chemical compound that is used as a reagent in the synthesis of various organic compounds, including aspirin.

Phosphoric acid is added as a catalyst to speed up the reaction between the salicylic acid and acetic anhydride. The combination of these reactants results in the production of aspirin, also known as acetylsalicylic acid, and acetic acid.

The synthesis of aspirin is an important chemical reaction that has numerous applications in the medical field. Aspirin is a widely used pain reliever and anti-inflammatory medication that is effective in treating a variety of ailments. The synthesis of aspirin involves the combination of a carboxylic acid and an alcohol through the process of esterification, resulting in the production of acetylsalicylic acid and acetic acid.

We hope this article on the aspirin formula is helpful to you. Weigh the dried recrystallized product on the filter paper and record the mass to 0. The theoretical yield is rarely obtained because of sources of error, side reactions, or other complications. This compound is stable in dry air but gets hydrolysed to acetic acid and salicylic acid when it comes in contact with moist air. Place a small amount of yield around 0. Conclusion: The main objective of the synthesis of aspirin lab was so produce aspirin acetylsalicylic acid through the reaction of salicylic acid and acetic anhydride. Ensure that your waste is disposed of correctly either in the "Non-halogenated" or "Halogenated" waste containers -"Non-halogenated"- chemicals containing ONLY C, H, and O -"Halogenated" - chemicals containing C, H, O, and halogens Any waste generated from either acid or base must first be neutralized with NaHCO3 and then poured down the sink -Flash point is the lowest temperature at which a liquid can form an ignitable mixture in the air near the surface of a liquid -The lower the flash point, the easier it is to ignite the material -For example, gasoline has a flash point of approximately -40 degrees C and is more flammable than ethylene glycol antifreeze , which has a flash point of 111 degrees C -4 diamonds - blue, red, yellow, and white -Blue: Health hazard 4 Deadly 3 Extreme danger 2 Hazardous 1 Slightly hazardous 0 No health threat -Red: Fire Hazard Flashpoints 4 Below 73 F 3 Below 100 F 2 Below 200 F 1 Above 200 F 0 Will not burn -White: Specific Hazard W - Water reactive OX - Oxidizing agent ACID - Acid CORR- Corrosive -Yellow: Reactivity hazard 4 May detonate 3 Shock or heat may detonate 2 Violent chemical reaction; water reactive 1 Unstable if heated 0 Stable.

The synthesis reaction of aspirin is shown below: The spectroscopic analysis of aspirin will involve the complexing of iron III to the deprotonated form of. . Choose Linear as the Fit Equation. Bring the solution to a boil quickly and limit the amount of time you are boiling the crystals in the solvent 9. Then, it is released into the blood stream and has pain-relieving effects How much of the reagents should you use? General Other errors that could not be avoided include losses in transferring substances and solutions and also in processes such as the filtration process and washing. As a result the vapour or gases formed in the reaction could have travelled up into reflux tube and left the system. The reason for this is because water was not travelling all around the reflux tube as there were residue particles inside it.
