Aspirin

In this experiment, acetylsalicylic acid or aspirin was synthesized by the esterification reaction between salicylic acid and acetic anhydride. This esterification reaction consisted of acetic anhydride with a carboxylic acid functional group and salicylic acid with an alcohol functional group making acetylsalicylic acid, which contains an ester functional group. Sulfuric acid was used as a catalyst to make the products of acetic anhydride and acetic acid. The experimental technique of crystallization

The history of aspirin is long beginning in 1763 with Edward Stone and is quite extensive including such names as salicylaldehyde in 1838 and salicylic acid and the white willow tree connection by the English. Kolbe in about 1850 and 1870 were involved. More recently, the Bayer and Hoffman companies were participants in some of the most leading contributors to the wide use and distributive properties of aspirin. The history of aspirin reaches as far back as 330 B.C and its functions in relieving

Synthesis and Characterization of Aspirin Product Identity and Purity After synthesizing a chemical, especially a drug, it is important to confirm the identity and purity of the product. You will perform three tests to examine the identity and purity of the aspirin that you synthesized. One test will detect the presence of leftover salicylic acid in the synthesized aspirin and allow you to determine its concentration. Government regulations stipulate that commercial aspirin must not contain residual

Aspirin a non-steroidal anti inflammatory drug(NSAIDs) with 3 main functions which are: analgesic, anti inflammatory, and antipyretic. NSAIDs is designed to inhibit the fatty acid COX enzyme which means that they also inhibit prostaglandins and thromboxanes. This enzyme is made up of COX 1 and COX 2. COX 1 is found in tissues and blood platelets which maintains homeostasis and produces prostaglandins. while COX 2 is responsible for the production of prostanoid mediators of inflammation. NSAIDs anti

Medicinal Agent – Aspirin IDC 3002H – EMWH Dylan Chow 9/14/2016 Abstract: In this experiment, aspirin was synthesized from a reaction between salicylic acid and acetic anhydride. Acetic anhydride was added to salicylic acid to create a solution and phosphoric acid was added to catalyze the reaction. After the salicylic acid was fully dissolved in a boiling water bath, water would be added to decompose the remaining acetic anhydride. Through the process of filtration, aspirin crystals were collected

Acetylsalicylic acid (ASA) or aspirin is a drug that is commonly used as an analgesic, to relieve pain without a loss of consciousness, to reduce fever and it is also used as an anti-inflammatory drug. It is salicylate drug and its salicylate was originally extracted from the willow bark plant which was discovered by Hippocrates, a very long time ago (1). After many research and trials it has come under consideration that Aspirin can be used as a preventive and as an anti-inflammatory drug for cardiovascular

Objective The current experiment introduces the concept of green chemistry on microwave heating to synthesise aspirin, instead of using conventional heating methods. Introduction Aspirin synthesis is a popular experiment undertaken in most organic chemistry teaching laboratories (Montes et al., 2006). Most experimental procedures for aspirin synthesis are undertaken to study the carbonyl nucleophilic substitution reactions either under basic or acidic conditions (Polshettiwar and Varma, 2008; Varma

product for the public. Aspirin is common over the counter pain relief medication used by a vast majority of society. Aspirin, Paracetamol and Magnesium are all examples of drugs used to relieve pain among society, but can these drugs aid in the growth of another organism like plants? In order to understand whether these drugs will have a positive or negative effect on these organisms, there must be some prior knowledge of how plants absorb nutrients and what the purpose of Aspirin is on the human body

Pharmaceutical Industry: Chemical Synthesis Production of Acetylsalicylic Acid I. Introduction Pharmaceutical industry is one of the biggest industry in the world as it involves drugs and medications - something that is very stable in terms of demand. This can be proven by the amount of sales as of 2012. Figure 1.1 shows the breakdown of the market of the pharmaceutical industry worldwide. However, aside from the production and synthesis of drugs and medications, the industry is also involved

In this discussion, I will be looking at the different forms of pain and how this pain is caused within the body. The number of different types of drugs used to treat pain is forever expanding but I will examine the main types of painkiller, how they were discovered and how they work to relieve the symptoms of pain. There are many different types of pain which can be categorised depending on how the pain is caused and how long the pain lasts. If pain results from tissue damage then it is called
