Aspirin (acetylsalicylic acid), caffeine and acetaminophen were isolated from four tablets of Excedrin that had a mass of 2.66 grams. Purity of each component was tested using Thin Layer Chromatography. The tablets were ground and then stirred in Ethyl Acetate to separate the components from their binders. Aspirin was isolated using 5% wt/vol NaHCO3, then caffeine was isolated using 4M HCl. The acetaminophen that remained was washed with deionized water and the Ethyl Acetate solution was kept. The
Experiment 19: Synthesis of Aspirin and Oil of Wintergreen The purpose of this experiment was to employ techniques to synthesize aspirin and oil of wintergreen and to purify crude aspirin via recrystallization. Additionally, techniques were learned to determine the purity of the synthesized organic molecule of acetylsalicylic acid using a back-titration method. The objectives of the experiment were achieved by synthesizing the organic molecules of acetylsalicylic acid (using salicylic acid and
This experiment explored the multi-step synthesis of synthesis acetylsalicylic acid commonly known as aspirin. A common procedure used in organic chemistry labs is multi step synthesis. this procedure involves a cascade of reactions that ultimately lead to a desire product. The series of reactions begins with commonly found or readily available reagents which are synthesized into products which can be used for a secondary reaction, and so on and so forth until the final desired product is synthesized
SYNTHESIS AND CHARACTERISTICS OF ASPIRIN- ACETYLSALCYLIC ACID Summary: The lab experiment was divided into parts and the synthesis of the aspirin occurred during the first week. 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. 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. Introduction: Aspirin (acetylsalicylic
Chemistry 322 Lab Report Part I. Synthesis and Characterization of Aspirin Part II. Extraction of Natural Products Name: Bianca Davis Instructor: Dr. Russell Date Submitted: December 8, 2014 Introduction Aspirin is a substance known as acetylsalicylic acid. It is used mainly as an over the counter drug used to relieve inflammation, pain, and fever. Its natural form is salicylic acid. This synthesis process requires the acetylation of salicylic acid with acetic anhydride. The purpose of this lab is to
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. 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
The Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th, 2011 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)
Synthesis of Acetaminophen Lab Report Bijal Patel, 20467049 Partner: Poojan Parikh T.A.’s: Long Pu CHEM 123L, Section: 006, Rm: ESC 149 Tuesday February 4, 2013, 2:30pm-5:20pm Experiment Done: Tuesday January 22, 2013 Introduction Acetaminophen was first introduced in 1955 (Richman, 2004). 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, 2004). It also has very
the market today is Ibuprofen which you may know as Motrin or Advil. 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,
