Aspirin is the most common over-the-counter drug that is produced. Aspirin can treat symptoms such as fever, inflammation, and can reduce the risk of a heart attack. The chemical name for aspirin is acetylsalicylic acid and it is made from the “reaction of acetic anhydride with salicylic acid in the presence of phosphoric acid as a catalyst”. (A. French et al., p.77) (CH3CO)2O + HOC6H4COOH ---H3PO4-→ CH3CO2C6H4CO2H + CH3COOH The purpose of the lab is to create aspirin using recrystallization
Aim : In this experiment, aspirin is to be prepared via an esterification reaction and purified through recrystallization. The purity of the synthesised aspirin is determined through melting point determination. Introduction : One of the most widely used medicine is aspirin. It is best known for its pain relief for mild headaches, toothaches and muscle aches. It also acts as a nonsteroidal anti-inflammatory drug by providing relief to the swelling. Salicin, an active ingredient in salicylic acid
E4 Synthesis of Aspirin and Oil of Wintergreen 10-2-15 Introduction Many everyday products are primarily comprised of organic molecules. Aspirin and the oil of wintergreen are esters, which is an organic compound that contains molecular connectivity. The esters usually have a pleasant and inviting aroma to them. Esters are used in cosmetics, perfumes, food, and pharmaceutical industry. Aspirin is the most used medication used worldwide. Aspirin is the common name for the compound acetylsalicylic
Chikungunya is a bacterial disease that is transmitted to people by mosquitoes. Outbreaks usually have occurred in countries such as Africa, Asia, Europe and areas close to the Indian and Pacific oceans. In late 2013, America had their first patient that had the virus chikungunya. It was found on the islands in the Caribbean’s. Travelers that travel the world are at high risk of getting this bacterial virus chikungunya. There is no vaccine or any type of medications that can prevent the bacterial
Task 2 Aspirin Tests 1. How pure was your sample? Under the ultraviolet light we could observe the purity of our sample (shown in the photograph on the right). 1 = our sample, 2= pure aspirin sample, 3= salicylic acid. You can see from the picture that my sample showed elements of both the pure aspirin sample and the salicylic acid sample. This means that my sample of aspirin is not pure as it contains some of the same properties of the salicylic acid meaning the reaction has not been complete
kill the microorganism and soothe your sore. No, due to the fact a sore indicates an open wound. I count on you are trying to reduce irritation by using ‘popping’ it? There are several methods to move approximately that, which include making use of aspirin to it topically. the important thing aspect is salicylic acid, which is likewise found in natural supplements consisting of white willow bark. do some research and see what

ASPIRIN SOLUTION UTILIZATION IN PECHAY (BRASSICA PEKINENSIS L.) PRODUCTION J. T. Bersabe INTRODUCTION Aspirin has different benefits and can cure some diseases like fever, indigestion, internal hemorrhage, pain and/or inflammation of body parts, headaches, menstrual periods, arthritis, colds, toothaches, and muscle aches. It can also reduce the risk of death in people who are experiencing or who have recently experienced a heart attack (Maryland, 2014). Salicylic acid, a major component of aspirin
Since 1970s, image retrieval is an effective research area. Image retrieval is a technique used for browsing, retrieving, and searching images from a huge database. Due to the advance technologies in the internet and digital imaging devices has been explosive growth of digital images. So, image retrieval technique is an efficient and effective for maintaining large database. There are two image retrieval schemes: text-based image retrieval and CBIR. Text-based image retrieval can be outlined back
In the documentary “In Sickness and in Wealth” as a society we ask is inequality making us Americans sick? This documentary explains the lives of a CEO, a janitor, an unemployed mother who volunteers and a lab supervisor. Americans who are on top of the pyramid have more access to resources and opportunities, as those who are at the bottom who face stress and exposure to a hazardous lifestyle. The one main key I want to point out is people who are of lower class in society are exposed chronic stress
