Their analgesic use is limited to mild aches and pains like backache and headache. Ex: Aspirin‚ Ibuprofen etc. Aspirin: Chemically aspirin is ortho acetyl salicylic acid. Preparation: Acetylation of salicylic acid with acetic

product‚ are done on a much larger scale in industry. The aspects they may differ in are equipment‚ time taken‚ and many other things. In this report I will explain how and why laboratory and industrial scale differ using the example of preparation of aspirin. The first difference is that instead of weighing the 2-hydroxybenzoic acid on scales on a work bench in a beaker as you would in small scale‚ it is easier and safer to weigh it onto scales‚ in a plastic bag on the floor. This is easier and safer

People in our community today including myself very commonly use it. In can be found in household cabinets‚ behind the counter medicines‚ in medicines themselves‚ and in nature. How the Molecule is Created Aspirin tablets of the same dosage amount are manufactured in batches. After careful weighing‚ the necessary ingredients

First aid Introduction First aid is the provision of initial care for an illness or injury. It is usually performed by non-expert‚ but trained personnel to a sick or injured person until definitive medical treatment can be accessed. Certain self-limiting illnesses or minor injuries may not require further medical care past the first aid intervention. It generally consists of a series of simple and in some cases‚ potentially life-saving techniques that an individual can be trained to perform with

Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

October 9‚ 2013 Partner(s): Acetylsalicylic Acid Synthesis Theory. This experiment was carried out to see how the hydroxyl group on the benzene ring in salicylic acid reacts with acetic anhydride to form an ester‚ and to make aspirin. Synthesis of Acetylsalicylic Acid occurs by protonation of carbonyl (C=O) group‚ and a nucleophilic attack of OH on the acetic anhydride. The ferric chloride test and melting point were used to test the purity of the results. A hypothesized recovery rater of above

Kawasaki Syndrome Heather Skinner Virginia College Professor Huffman January 23‚ 2017 Kawasaki Syndrome was first discovered by a Japanese physician Tomisaku Kaswasaki in the 1960s. He noticed a cluster of symptoms in Japanese schoolchildren. Kawasaki Syndrome affects children younger than the age of 5 years old‚ but peaks at ages 18-24 months. In 2000‚ there was an average of 77% of children in the United States being treated for Kawasaki disease (Gale‚ 2008). The disease appears to be influenced

The purpose of this experiment is to determine the components of an unknown drug and identify it as one of six (6) commercial drugs by using thin-layer chromatography. I added approximately a quarter of a tablet of acetaminophen‚ aspirin‚ caffeine‚ ibuprofen‚ salicylamide‚ and the unknown (#19) to separate test tubes containing 2.5mL of dichloromethane. I noticed that my unknown was a coated tablet. Each test tube was swirled until the greatest amount of each solid was dissolved.

as pharmaceutical chemistry. Synthesizing aspirin is a common example of a multistep synthesis reaction. Aspirin is typically taken as a painkiller or as a reducing-agent for fevers. In order to synthesize this product‚ the reactants salicylic acid and acetic anhydride (in excess) are used in the presence of a catalyst to create the product acetylsalicylic acid and acetic anhydride. Acetylsalicylic acid is the active pharmaceutical ingredient in aspirin and the catalyst is not consumed in the reaction
