It is, however, still a possibility. Our sample mass was 0. When the Aspirin is done drying, transfer it to the mortar and use the pestle to grind it into a fine powder. Daniels Organic Chemistry 2121 11 February 2014 Synthesis of Aspirin Salicylic acid derivatives, or salicin, are found in the bark of the willow tree. This can be observed in both the use of Phosphoric Acid in the synthesis part of the experiment and the use of scratching the side of the beaker to induce crystallization. Then, a vacuum filtration apparatus was set up. Taking this into account, the actual mass of the crude aspirin product is reduced to 2.

However, a thorough reinstall of the Operating System is a time-consuming task that involves lengthy back-ups, long installations, and days to find and reinstall all of your favorite programs. Synthesis produced significantly high percent yields for aspirin, however, produced extremely low and impure percent yields for Tylenol. Once the beaker is cool enough to handle, take it back to the lab bench and attempt to induce crystallization by scratching the side of the beaker with the stirring rod. Age of Enlightenment, Arranged marriage, Economics 486 Words 3 Pages Conclusion In part A of this experiment, we transformed the bacteria into an antibiotic resistant form by inserting a plasmid into it. Though the experiment proved the hypothesis to stay true, several improvements could have been made to the procedure.

The active ingredient in aspirin was found to be salicylic. Acetic acid, Acetic anhydride, Acetyl 973 Words 4 Pages Lab Report Synthesis and Characterization of Aspirin Acetylsalicylic Acid The Synthesis and Characterization of Aspirin Acetylsalicylic Acid. Simple removing a virus can actually harm your system. As for the melting point data, the range of the crude sample was 120-124˚C and the range of the purified sample was 122-124˚C. Catalysts do not change the composition of the final product, however, and this is also visible in Figure 2.

In Table 8, the differentiation of synthesized acetylsalicylic acid from commercially available aspirin was accounted for. When the aspirin was prepared, it was isolated and filtered. Taking this into account, the actual mass of the purified aspirin product is reduced to 0. After the sample has dried for 5 minutes, turn off the vacuum filtration apparatus and retrieve the crude product from the Buchner funnel and place it in the previously weighed weigh boat. Next perform the phenol test.

Acetic acid, Acetic anhydride, Acetyl 1228 Words 4 Pages Jeana Greaves Chem3301-112 June 19, 2013 Synthesis of Aspirin from Methyl Salicylate Introduction The synthesis of Aspirin Acetyl Salicyclic Acid began with methyl salicylate and sodium hydroxide as the reagent. In this case, an acetyl group was added to salicylic acid, a naturally occurring compound with significant pharmaceutical value. Acetic acid, Acetic anhydride, Aspirin 4543 Words 19 Pages Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid aspirin , and to become familiar with the optimum conditions needed for successful yields. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Rinse the Aspirin in the filter crucible by putting 10 mL of chilled water in the aspirator, stirring it well, and then allowing the water to be quickly suctioned away. This is done by weighing out a carefully measured amount of product and fully dissolving it in a certain amount of water. Purification is needed to eliminate any salicylic acid and acetic anhydride that did not react, as well as the acetic acid product and phosphoric acid.

Synthesis of Aspirin By: Jon Torre Purpose: To determine which of four catalysts yields the fastest reaction rate in the acetylation of salicylic acid 1 to form acetylsalicylic acid 2. This method of forming acetylsalicylic acid is an esterification reaction. The experiment could be improved upon in many ways. The purpose of this experiment, is essentially to determine the purity of the product that is collected and filtered and recrystallized. N-acyliminium is a better electrophile than acetic anhydride due to the withdrawal of electron density from the electrophilic carbon by the nitrogen of the pyridyl ring. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis.

Step 8 Step 10 The mixture was heated for 15 minutes in a bath of boiling water. This concept is used in the first part of the lab; when we have to produce crystals of aspirin. The percent yield of purified aspirin product was 5. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. Later it was found that the treatment did not actually cure malaria, but instead just reduced the fever of those with the disease.

During the synthesis, the H+. Aspirin is a pain reliever and a fever reducer. Another laboratory technique used in this experiment is recrystallization. The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Summary Much was learned in this experiment.

These independent variables are the amounts of Salicylic acid, Acetic Anhydride, water and any other substances used in the experiment, the temperature of the water used in the experiment, the time spent performing certain tasks, and any other variable that is controlled by the user. Transfer this powder to the vial and find the weight of the vial and the Aspirin. While many variables can change in the experiment, there are many variables that are independent controllable as well. The infrared spectrum for the experimental. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static, and though the mouse cursor still moves on the screen, neither typing on the keyboard nor clicking the mouse produces any effect in the program's windows.
