Synthesis Of Aspirin

Synthesis of Aspirin Erin Chase Arellano CHEM 12A ABSTRACT Acetylsalicylic or most commonly known as Aspirin is made through a combination of salicylic acid and acetic anhydride. It is use to relieve mild to moderate pain such as muscle pain, headaches and common cold and reduce fever. The objective of this experiment was to synthesize aspirin from salicylic acid and acetic anhydride. The purity of aspirin was tested using the ferric chloride test and % yield was also calculated. Below drawing

objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore, the other objectives were to enable students to conduct the synthesis of aspirin, reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining its melting point and percent yield. Soluble impurities

Organic 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

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)

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

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

Abstract This report presents the synthesis of Aspirin (acetylsalicylic acid), as the product of the reaction of salicylic acid with ethanoic anhydride under acidic conditions. Aspirin was purified through recrystallisation by vacuum filtration, followed by desiccation of the Aspirin crystal over silica gel. The percentage yield was calculated as 44.89% and a sample of Aspirin was analysed using infra-red spectroscopy and compared to the spectrum of pure Aspirin, this served as an introduction to

Olivia Isaacs C127 11 November 2014 The Synthesis and Characterization of Aspirin Objective: In this experiment, aspirin was synthesized from acetic anhydride and salicylic acid made in order to characterize its properties and determine its purity. The purity of the aspirin was examined by its melting point, thin layer chromatography, and UV spectroscopy. Introduction: Aspirin is synthesized by the formation of acetic anhydride and salicylic acid with the presence of a catalyst (Salicylic Acid

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 acid 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 initiate

Aspirin Synthesis Organic chemical synthesis is the process of creating a different substance from two or more existing substances. It can be done naturally or through man made techniques. Synthesis has been going on for ages, although there was a time that we did not actually know that was what we were doing. The first conscious synthesis was when urea was made in 1828. Since then, this science has continued to become more developed and since World War II it has been growing exponentially. A complete
