What is Aspirin? Aspirin is on of the first drugs to ever be commonly used and is still one of the most widely used in the world. How widely used you ask? Approximately 35000 metric tonnes are produced and consumed every year. Chemically aspirin is known as acetylsalicylic acid with the chemical formula of C9H8O4. Aspirin is an analgesic‚ anti-inflammatory‚ antipyretic‚ and is an inhibitor of platelet aggregation. The history of Aspirin Aspirin has been a major part of just about everyone’s

“Aspirin has been used for many years; it is well-understood‚ effective‚ inexpensive and widely available.” - Dr. Jeffrey Berger In the last 30 years medicines prescribed by doctors have changed beyond all recognition. Our better knowledge of the nature of diseases and their management has led to the replacement of many old remedies by new ones specifically designed for each illness. Everyone has known for years that

Panacetin). Isolation of Aspirin: The organic filtrate was extracted through a separatory funnel with 32 mL 5% sodium bicarbonate to produce an aqueous layer and a dichloromethane layer. 7.2 mL 6 M hydrochloric acid were added to the aqueous layer until the pH was 2. The mixture was then cooled in an ice/water bath for 10 minutes. The aspirin was collected by vacuum filtration. After it dried‚ it yielded 0.93 g (30.9 % of original Panacetin). Isolation of Unknown: 71 mL of boiling H2O were poured

INTRODUCTION: Penicillin is the basis for most of the antibiotics in the world just as aspirin is the basis for many drugs. Therefore‚ if there had been only two drugs to invent‚ it would be down to penicillin and aspirin. Hippocrates‚ the father of modern medicine lived sometime between 460 B.C and 377 B.C. Hippocrates has left historical records of pain relief treatments‚ including the use of a powder made from the bark and leaves of the willow tree to help heal headaches‚ pains and fevers.

effects for some people‚ yet it is safe enough to be sold without a prescription. Because it is easy to prepare‚ aspirin is one of the most inexpensive drugs available. It is produced in vast amounts. In fact‚ industry makes 43‚000‚000 pounds of the drug every year. This microscale experiment will permit you to make an amount of aspirin equivalent to about 1/2 of that found in an aspirin tablet. Purpose: To synthesize acetylsalicylic acid on a microscale basis.

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

Soluble aspirin tablets Adult dosage: To treat pain or fever in adults‚ the recommended dose is 325 mg to 650 mg every 4 to 6 hours as needed. The maximum daily dose is 4‚000 mg‚ unless otherwise directed by your doctor. For adults with conditions caused by inflammation such as rheumatoid arthritis‚the usual dose is 975 mg 4 to 6 times daily on a regular basis. Sometimes‚ higher doses may be used. To treat migraine headache pain‚ the recommended adult dose is 1‚000 mg at the onset of pain or

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) and

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
