What is the more formal chemical name for aspirin? Acetylsalicylic acid 2. Using your data from Experiment 2‚ how can you be sure you synthesized aspirin? By using the colors as a guide‚ we can compare the Acetylsalicylic acid + 8 mL FeCl3 to the Aspirin Crystals from Experiment 1 + 8 mL FeCl3 in order to see if it synthesized. 3. Would you say that your synthesized aspirin is relatively pure? How can you tell? One way that the purity of aspirin can be judged is by it’s color as pure acetylsalicylic

Conclusion: The purpose of this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. 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. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring

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. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction Aspirin is a

Synthesis Conclusion: Conclusion: As we can see‚ the sources show us that during the Enlightenment period money was very important. It shows that during the time people would do merely anything for money‚ even force their children into arranged marriages or‚ as Voltaire suggest satirically‚ sell them as a food source. Parents or even the brides and grooms themselves would arranged marriages for economic gain. This was not always the case. We have learned from She Stoops to Conquer that‚ although

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

aspirin Intro- Aspirin is known as a pain reliever for muscle ache‚ head ache and can prevent heart attacks as well as blood clots‚ and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride
