Aspirin

Acetylsalicylic acid is the active pharmaceutical ingredient that is found in aspirin and is used to treat inflammation, pain and fever. It is created by an esterification reaction of salicylic acid with acetic anhydride in the presence of an acid catalyst. At the end of the reaction, a product and unreacted salicylic acid and acid catalyst was created. The product contains impurities, such as acetic anhydride and salicylic acid, which needs to be removed. Crystallization, a technique used to purify

Salicylic Acid in the aspirin was the change in color from white to dark purple. The color that indicated the lack of Salicylic Acid was light yellow. Conclusion The weight of crude aspirin obtained from 4g of Salicylic Acid was 4.74g. After recrystallization, approximately 2.9g of recrystallized aspirin was obtained. After calculating the molar mass of Salicylic Acid and aspirin, the theoretically obtainable weight of aspirin was 5.217g. The percentage of theoretical crude aspirin obtained was 90.85%

magic pill that makes plants grow? There may be an answer to that question; some speculation says that pill could be aspirin. I have always wondered if there was some sort of quick fix or magic pill to help plant growth. Through research done on the Internet I have collected a sufficient amount of evidence. I believe that learning about plant biology may help explain why aspirin could help plant growth. Plants are very complex and are made up of many different parts. Plants have several different

Introduction Widely used all over the world, organic compounds, drugs, are constructed through the pharmaceutical method of organic synthesis. The most common drug is acetylsalicylic acid, known commonly as Aspirin. C_7 H_6 O_3 (s)+C_4 H_6 O_3 (aq)→C_9 H_8 O_4 (s)+C_2 H_4 O_2 (aq) In this experiment, Aspirin, along with acetic acid, was a product of the chemical reaction between salicylic acid and acetic anhydride – as shown by the chemical formula above. The product, acetylsalicylic acid, shows three structural

Talk about how willow bark was once used to relive pain but had severe side effects such as internal bleeding within the stomach   The production of aspirin begins salicylic acid which has been derived from the active site of salicin found in willow bark. This is done through multi-step process where substrates of salicin are converted into more basic products such as salicylic acid. Salicylic acid cannot be consumed by itself due to the fact that it is bitter and irritates the stomach causing side

solvents such as dichloromethane (DCM) while Aspirin is soluble in DCM. Primarily, sucrose was removed so that it can be separated easily from the functioning ingredients that were present in Panacetin. Given that sucrose would not be able to dissolve if Panacetin was directly dissolved in the DCM. Aspirin however, is insoluble in water but it is known to contain a carboxylic acid group so it then will be able to react with sodium bicarbonate that is why the aspirin was recovered by reacting the conjugate

1. Aim To determine the percentage of aspirin in different commercial preparations and to find which is the best value for money 2. Hypothesis The greater the percentage of acetylsalicylic acid (ASA) in the tablet, more powerful and efficient the aspirin would be due to the way aspirin works in human’s body. Aspirin is often used to alleviate the pain, and the sensation of pain is mainly attributed to a chemical substance called prostaglandins, which is responsible to send a strong signal

polymers, fuels, soaps, detergents, drugs and medicines. These, if carefully designed, have important properties for the improvement of mankind. One such example of manipulating organic compounds through chemical reactions is the development of Aspirin and later, other associated analgesics or non-steroidal anti-inflammatory drugs. Brady Grindrod 2014 Organic chemistry, often termed the ‘chemistry of design’, is the chemistry of carbon compounds. It deals with the structure, properties and reactions

containing aspirin, acetaminophen, and caffeine and is owned by GSK and Novartis (Sun, 2014). The three components of Excedrin all have useful medicinal properties for reducing migraines for Excedrin users. Acetaminophen is a painkiller that directly affects the central nervous system, it relieves fever and aches and pains. Aspirin is also a pain reliever that can reduce headaches and pains, but unlike acetaminophen aspirin can also reduce swelling in patients. In Excedrin, acetaminophen and aspirin are

! Isolation of the Components of BC Powder Introduction Aspirin, Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this, the three components were forced into conjugate acid (or base) forms, causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel
