Salicylic acid

The term salicylate refers to any of a group of chemicals that are derived from salicylic acid. The best known is acetylsalicylic acid (Aspirin). Acetylsalicylic acid is metabolized to salicylic acid (salicylate) after ingestion. Salicylates are nonsteroidal anti-inflammatory (NSAI) agents commonly used for their analgesic and antipyretic properties. They act on the cyclooxygenase enzymes to impair peripheral and central prostaglandin biosynthesis. (1) Planned salicylate overdose usually occurs

Salicylic Acid Testing Observations - The indicator that showed the presence of Salicylic Acid in the aspirin was the change in color from white to dark purple. The color that indicated the lack of Salicylic Acid was light yellow. Conclusion The weight of crude aspirin obtained from 4g of Salicylic Acid was 4.74g. After recrystallization, approximately 2.9g of recrystallized aspirin was obtained. After calculating the molar mass of Salicylic Acid and aspirin, the theoretically obtainable weight

The medical field uses acids and bases all of the time because, our body uses acids and bases every day to try to get the PH levels as neutral as possible in our bodies. The neutral PH level in our bodies is 7.3.When your organs stop neutralizing acids and bases you need medical help. If the pH-level goes over an acidity or basic level it can be really dangerous. That applies to almost every reaction in your metabolism. Due to the fact that our body needs, and produces acids and bases, I’m going to

Discussion: In this experiment we added salicylic acid to 2.0 ml acetic anhydride for the molecules to react to produce aspirin. The 85% concentrated phosphoric acid was added to act as an acid catalyst to lower the required activation energy for the reaction. We then allowed the reaction to stand for about 10 minutes to allow the phosphoric acid to spread through the solution. We than heated the solution to add energy to the system to obtain the activation energy needed for the reaction. After heating

EXPERIMENT 4: Synthesis of Salicylic Acid from Wintergreen Oil Abstract: The purpose of this experiment is to take methyl salicylate (wintergreen oil) and by heating it under reflux with NaOH as a solvent, and then cooling the mixture with H2SO4 as another solvent, synthesize salicylic acid. The final step involves purify the product to produce as pure a sample of salicylic acid as possible. This process allowed for the successful production of 1.406g salicylic acid, an 82.70% yield. The NMR and

1. First, 3.0015 g of salicylic acid were measured using an electronic balance. 2. The salicylic acid was then transferred into a 150 mL beaker. 3. Using a 10 mL graduated cylinder, 9.20 mL of acetic anhydride was measured. A watch glass was placed on top of the graduated cylinder to prevent the spread of acetic anhydride fumes. 4. The acetic anhydride was then added to the salicylic acid. This step was performed under a fume hood. 5. Next, 15 drops of 85% phosphoric acid were added to the solution

#15 Synthesis of Ethyl Salicylate from Salicylic Acid ____________________________________________________________ _______________ Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol. Yields of salicylic acid (week 1) and ethyl salicylate will be found, as well as the overall yield of the 2-step conversion of acetyl salicylic acid to ethyl salicylate. Introduction: Esters are formed from the reaction of acids and alcohols: O O

The purpose of this experiment is to separate a mixture of salicylic acid and naphthalene using extraction, recrystallization and sublimation techniques. Extraction is the separation of compounds from a mixture based on their relative solubilities in different solvents. Sublimation is the process of separation by which a substance transitions from the solid phase into the gas phase, skipping the liquid phase. Recrystallization involves dissolving a substance in an appropriate solvent then crystallizing

Pharmaceutical Industry: Chemical Synthesis Production of Acetylsalicylic Acid I. Introduction Pharmaceutical industry is one of the biggest industry in the world as it involves drugs and medications - something that is very stable in terms of demand. This can be proven by the amount of sales as of 2012. Figure 1.1 shows the breakdown of the market of the pharmaceutical industry worldwide. However, aside from the production and synthesis of drugs and medications, the industry is also involved

2004) Aspirin and salicylic acid products are the active ingredients of hundreds of therapeutic and OTC products. These products are used in analgesics, anti-inflammatory agents, and antipyretics, in
