The number of moles of the purified aspirin product after extraction was 7.77 x 10-4 as shown in Equation 4. These two moles calculated a chemical yield of 54.3% as shown in Equation 5. The melting point of the pure aspirin product was ranged at 117.8-125.2C as shown in Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals

Aspirin were used to relieve pain‚ inflammation‚ and fever. Aspirin were made using a combination of salicylic acid and acetic anhydride.The goal of this experiment was to determined the purity of aspirin using different methods. These methods included‚ reacting salicylic acid with FeCl3‚ finding its melting points‚ and by doing Thin-layer chromatography. When you reacted salicylic acid with FeCl3‚ changes in color will occur. Pure Aspirin has a melting point around 135°C and a pure salicylic acid

When I carried out the experiment to produce an aspirin sample I had to take a few results I had gained from carrying out the experiment later used these to work out the experimental error and percentage % yield. The results I used where the published value of what temperature pure aspirin melts at‚ the temperature my aspirin sample melted at‚ the weight of pure aspirin and the weight of impure aspirin. Firstly I worked out the experimental

It should stress the information of little side effects compared to other analgesic medicine. Both the retail price and the trade price should be lower than Tylenol. Segmentation and targeting: Datril should target on aspirin users. Datril potential clients could be 1) people currently using aspirin 2) people currently

Aspirin has been a pain reliever for more than 100 years. Aspirin has been used as a remedy for many illnesses for centuries now and still more things are yet to be identified about aspirin and its uses. It was recently discovered that aspirin can be used to reduce clotting of the platelets in the blood vessels‚ thus reducing the risk of heart attack in humans. Most students in their youthful age were not able to give their heart the maximum care it deserved‚ as a result‚ it leads to heart related

Explaining what Aspirin is. An aspirin is a medication used as a treatment to those who are suffering from mild conditions‚ such as fever‚ pain‚ and/or inflammation. It’s helpful use is to give aid to those who are suffering from toothaches‚ common colds‚ chest pain‚ headaches‚ and many more symptoms of mild pain‚ fever‚ or inflammation. It is also known to reduce blood clotting. Its scientific name is acetylsalicylic acid (ASA)‚ with it’s chemical formula being C9H8O4‚ and its IUPAC name being 2-acetyloxy

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
