Aspirin

 Rebecca Boreham 7/1/14 Chem 2423 Experiment #5 Synthesis of Aspirin Elizabeth Ajasa Kaylee Seymour Lauren Hatfield Suveda Perikala Introduction/ Purpose Aspirin is the most commonly used drug in the United States. Forty million pounds are produced each year. The chemical name for aspirin is Acetylsalicylic acid. Aspirin is a pain reliever and a fever reducer. Aspirin originated from the bark of a White Willow Tree. Chewing the bark however is extremely acidicand irritates the mucous membranes...

Synthesis of Aspirin

Synthesis of Aspirin from Oil of Wintergreen Objectives: In this experiment, the Oil of Wintergreen is put into an Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. The solution is then refluxed which means that the solution will be boiled in a base, then condensed in a condenser. This replaces the carbon on the ester at carbon 1, with an oxygen atom which will have an ionic bond with a sodium anion. This yields sodium salicylate which will be acidified in methanol...

Synthesis of Aspirin

Jennie K. Daniels Organic Chemistry 2121 11 February 2014 Synthesis of Aspirin Salicylic acid derivatives, or salicin, are found in the bark of the willow tree. In the 5th century B.C., Hippocrates ground the bark into a powder, and later, the Natives Americans chewed on the bark to alleviate fever and pain1. In the 19th century, a German chemist by the name of Felix Hoffman wanted to find a medication that would ease...

Synthesis of Aspirin

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...

Synthesis of Aspirin

 EXERCISE 11 SYNTHESIS OF ASPIRIN MARAVILLA, Ana Mikaela B Group 4 CHEM 40.1 1L Date performed: September 30, 2013 Date submitted: October 7, 2013 VI. RESULTS AND DISCUSSION Aspirin is prepared by the esterification of salicylic acid with acetic anhydride under acidic conditions. The phenol group in salicylic acid is replaced by a carboxyl group through electrophilic substitution. The mechanism for...

Aspirin Essay

Aspirin or acetylsalicylate acid is a compound that is widely used in medicine. The use of aspirin in medicine began long before the active reagent was removed from its natural source. The first documented use of aspirin was found in the writings of Hippocrates, the so called father of medicine. Hippocrates prescribed that willow bark could be used to remedy a wide range of conditions such as pain, fever and inflammation. Scientists began to seek to extract the active compound from willow tree bark...

Synthesis of Aspirin

Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment, we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C, therefore our percent...

Synthesis of Aspirin

Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon, hydrogen and oxygen.  The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin, the most...

Aspirin Preparation

Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain. Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw recrystallization. I will then obtain a melting point of my product to get an estimate of its purity. By the end...
