Aspirin Synthesis Lab Report by Alissa Lockwood on Prezi


Synthesis and Characterization of Aspirin Product Identity and Purity After synthesizing a chemical, especially a drug, it is important to confirm the identity and purity of the product. You will perform three tests to examine the identity and purity of the aspirin that you synthesized, preparation of aspirin lab report. One test will detect the presence of leftover salicylic acid in the synthesized aspirin and allow you to determine its concentration.

Government regulations stipulate that commercial aspirin must not contain residual. It is an over-the-counter drug that relieves pain and reduced fevers. Acetaminophen is considered an alternate to aspirin since it does not irritate the stomach Richman, preparation of aspirin lab report, It also has very. The Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th, Purpose: The purpose of this lab was to synthesize aspirin, determine the theoretical yield, compare the percent yield to the theoretical yield and test the purity of aspirin by adding Iron III chloride to the product.

Hypothesis: I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid aspirin. Both drugs are identical except for quantity and price, and even there it might be the same. The organism I chose to work with is a crustacean called the Daphnia. Later in this report I will attempt to explain the significance of that organism and why I chose to conduct tests on it.

I then, with the information at my disposal, conjured a hypothesis which I would test. Using the materials at hand I, to the best of my ability tested. Upon admission Chest X-Ray showed generalized hyperinflation and right middle and lower lobe infiltrates. Traditional treatments include Tylenol, aspirin, or other non-steroidal anti-inflammatory drugs NSAIDsbut the long-term negative effects of these drugs combined with the fact that they offer only short-term relief has led doctors and scientists to search for better treatment options.

She reports gaining 1 to 2 pounds every day since her discharge. What error in teaching most likely occurred when M. A breakdown of successful communication occurred regarding when to call with early weight gain.

It is imperative. The patient describes the pain as pressure in the center of his chest. He reports the pain is now radiating down his left arm and through to his back, he is diaphoretic, and complaining of shortness of breath. He denies nausea or vomiting. Smith reports no previous history of chest pain or pressure.

He smoked one pack of cigarettes daily for 13 years but quit smoking last year, preparation of aspirin lab report. He denies a family history of.

Abstract: The goal of this experiment was to synthesize aspirin. In this experiment aspirin, also known as acetylsalicylic acid, was synthesized from salicylic acid and acetic anhydride. In the reaction the hydroxyl group on the benzene ring in salicylic preparation of aspirin lab report reacted with acetic anhydride to form an ester functional group. This method of forming acetylsalicylic acid is an esterification reaction.

Since this esterification reaction is not spontaneous, sulfuric acid was used as a catalyst to preparation of aspirin lab report the reaction. After the reaction was complete some unreacted acetic anhydride and salicylic acid was still be present in the solution as well as some sulfuric acid, aspirin, and acetic acid.

Crystallization, which uses the principle of …show more content…. Hofmann worked for Bayer, preparation of aspirin lab report, which then named acetylsalicylic acid compound aspirin.

Aspirin became commercially available in and today it is estimated that over a trillion aspirin tablets have been consumed by those in need of its curative effects. In this experiment aspirin was synthesized from salicylic acid and acetic anhydride. Salicylic acid was esterfied using acetic acid and sulfuric acid acting as a catalyst preparation of aspirin lab report produce acetylsalicylic acid and acetic acid.

The phenol group that will attack the carbonyl carbon of the acetic anhydride is the —OH group that is directly attached to the benzene since it is more basic than the —OH group attached to the carbonyl group. Sulfuric acid serves as the acid catalyst since its conjugate base is a strong deprotonating group that is necessary in order for this reaction to be reversible.

The need for the strong conjugate base is the reason why other strong acids such as HCl is not used since its conjugate base Cl- is very weak compared to HSO After the reaction was complete some unreacted acetic anhydride and salicylic acid was still be present in.
