Introduction: The purpose of this lab was to learn how to use salicylic acid to make aspirin. Aspirin is the most widely used over-the-counter drug in the world. The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Aspirin is used to relieve pain‚ reduce inflammation‚ and lower fever. Aspirin originally was derived by boiling the bark of the white willow tree. Although the salicin in willow bark has analgesic properties‚ purified

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

Abstract For the amount of aspirin in a commercial tablet to be determined‚ different solutions of acetylsalicylic acid mixed with NaOH were created at different concentrations. All the different solutions were then analysed using Novaspec photometer‚ which allowed for a graph to be created and a line of best fit to be made. The amount of aspirin in a commercial tablet was found to be 350mg. Introduction The molecular formula for aspirin‚ also known as acetylsalicylic acid‚ is C9H8O4. It is most

OF ASPIRIN Aspirin in general is a safe drug but the ability to prevent blood clots is connected to some side effects. Aspirin can cause firstly stomach irritation. That’s means aspirin can irritate your stomach which has as a result pain‚ nausea‚ vomiting or hearburn. Sometimes can have other symptoms like bleeding‚ holes in stomach or intestines. In order to minimize these problems it should be better to have a full stomach. Also another problem that comes from aspirin can

Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

Reshmi Nair Title: Determination of Aspirin through back titration. Aim: To determine the concentration of Aspirin in a tablet using NaOH and Hcl. Research Question: What is the concentration of Aspirin in a normal tablet? Background: Aspirin is the general name for acetylsalicylic acid (ASA); it is also the trademark of the drug produced by Bayer in Germany. In eighty countries‚ aspirin is a registered trademark‚ but in other places the term aspirin refers to ASA by itself or as an ingredient

In our search for prosperity‚ growth and success‚ we are destroying the system that we as human are completely dependent upon. Population growth‚ water-intensive agriculture and economic development are using water faster than it can be replenished. Our Earth is a place where beauty exists‚ a place where 6.6 billion people and 15 million other species live‚ a place filled with 1.4 cubic kilometers of water. Although 70% of the planet’s surface is blanketed with deep oceans water‚ freshwater only

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 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

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
