We let the flask start to cool, during which time we began to see the crystallization of aspirin.

Acetaminophen was first introduced in 1955 (Richman, 2004). Figure 1: Reaction of Aspirin (Snelling, 2013) MATERIALS AND METHODS Goggles Gloves Lab … Prepare the synthesized aspirin sample for testing. Aspirin Synthesis Lab Report - Aspirin Synthesis Lab Report Intro The objective of this lab is for us to learn how organically synthesize a product in, 8 out of 9 people found this document helpful, The objective of this lab is for us to learn how organically synthesize a, product, in this situation Aspirin, and ensure that the product that we receive is, actually a pure substance.

The process we will use will lead, to the formation of aspirin crystals. Aspirin is primarily used to treat pain as well as to avert cardiovascular disease.
Genetically Modified Foods, Pros and Cons persuasive essay.
The lab experiment was divided into parts and the synthesis of the aspirin occurred during the first week.

Synthesis of Aspirin By: Jon Torre. After all the water was gone we kept the vacuum filtration apparatus on for a few minutes to help dry the aspirin crystals. Another way would be to test it via the reaction of ferric chloride. The purpose of this lab is to synthesize and characterize high purity aspirin.
Experiment 19: Synthesis of Aspirin and Oil of Wintergreen
Synthesis of Aspirin Lab Report.
The possible reasons for this are that we did not get all of the aspirin out of the Erlenmeyer flask, leaving some crystals on the glass surface. Purpose: To determine which of four catalysts yields the fastest reaction rate in the acetylation of salicylic acid (1) to form acetylsalicylic acid (2).
Aspirin is an organic ester.
explain the significance of that organism and why I chose to conduct tests on it.
We put our watch glass with the filter paper and the crystals into a box and Dr. Greenberg placed it in a dry area until our next lab a week later so it could completely dry. Tuesday February 4, 2013, 2:30pm-5:20pm Temp (C/F Site) Pulse (Site) Respiration Pulse Ox (O2 Sat) Blood Pressure Pain Scale 1-10
Chemistry Standard Level Lab Report After the liquid stopped giving off vapors, we then removed the flask from the water bath and added 18-20mL of water. and price, and even there it might be the same.
2 Theory 1
RELATED WORK: Synthesis of Aspirin Lab Report . Add 15ml of distilled water to the beaker. Date Submitted: December 8, 2014 Quickly transfer the flask to and ice bath. In this experiment aspirin, also known as acetylsalicylic acid, was synthesized from salicylic acid and acetic anhydride. 4.4 Appearance 4 Using 4.032g of salicylic acid 8.0mL of acetic anhydride on a hot bath the reaction was speeded up by the use of a catalyst phosphoric acid.
The temperature of an alcohol thermometer was equilibrated in a beaker of room temperature tap water. Ns]��������rV�����Ț�. An ester is a compound that is formed when an acid reacts with an alcohol, -OH group.
3 Procedure 2
After synthesizing a chemical, especially a drug, it is important to confirm the identity and purity of the product. Patient Initial T.M. SYNTHESIS OF ASPIRIN (acetylsalicylic acid) Place 2.0 g (0.015 mole) of salicylic acid in a 125-mL Erlenmeyer flask. • Work in the hood when indicated in the procedure.
History of Present Illness including Admission Diagnosis&
Date: December 8th, 2011
It is used mainly as an over the counter drug used to relieve inflammation, pain, and fever.
Excess anhydride reacts with water produced in esterification, which shifts the equilibrium in the forward direction and gives a better yield of the desired project. Bijal Patel, 20467049 Acetaminophen is considered an alternate to aspirin since it does not irritate the stomach (Richman, 2004). In the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group.
Introduction.
Later in this report I will attempt to A “purified product” can be obtained through recrystallization of the crude product in hot ethanol. Clearly, acetic anhydride (alcohol) reacts with salicylic acid (acid) to yield the ester (aspirin), as was shown by the crystals that formed and dried over a week that measured in at 2.28g.
Once the sample was then left to dry in the drawer for a week using the melting point apparatus we conducted the purity assessment of the dried sample. Get 2g of salicylic acid, 5mL of acetic anhydride, and 5 drops of concentrated, phosphoric Acid. Data Collection and Processing and Conclusion and Evaluation
After fifteen minutes remove the cotton plug and slowly drop 2mL of water, into the flask to stop the reaction. Activity 1: Synthesis of Aspirin.
The purpose of this experiment was to make aspirin via esterification, and to determine the percent yield we as a lab group made.
Allow the mixture to heat for 15 minutes. 1 Introduction 1 0.04g of synthesised aspirin and transfer it to a 25ml beaker. We then took a watch glass, cleaned it, put our initials on it, weighed it, and put this in our data table.
4 Results and Calculation 4 Lab Report Such compounds lower …
In order to accurately determine the yield of our aspirin it needed to be completely dry. Mix the solution.
A catalyst, normally sulfuric or phosphoric acid is used to increase the rate of reaction (Cengage 91-94). g Aspirin 138g Aspirin, Therefore our theoretical yield for our amount of aspirin to be made is 2.623g, % yield = Actual yield x 100, So: 2.28g x 100 = 87.02% actual yield.
g aspirin, 138g Salicylic Acid = 2.011g Salicylic Acid = 361.98g Salicylic Acid = 2.623g, 180g Aspirin ? 3.3 Recrystallisation 3
In this laboratory activity you will synthesize aspirin, a derivative of salicylic acid. 4.2 Percent yield 4 Complete this step quickly; Measure approx. I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid (aspirin), Synthesis of Acetaminophen The synthesis reaction of aspirin is shown below: Since acetic acid is very soluble in water, it is easily separated from the aspirin product. We will also be able to.
The organism I chose to work
1.1 Objective 1
Hofmann worked for Bayer, which then named acetylsalicylic acid compound aspirin. Part II. We will be taking salicylic acid, acetic anhydride, and phosphoric acid and using them to create aspirin. 101 115 31 90% on oxygen 2 L/min via nasal cannula 170/96 4 74 Experiment 5 • Synthesis of Aspirin 5Expt. It is an over-the-counter drug that relieves pain and reduced fevers. this procedure involves a cascade of reactions that ultimately lead to a desire product.
