    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

    Laboratory 5: Synthesis of Organic Compounds Introduction: In this experiment, aspirin will be synthesized from salicylic acid using acetic anhydride. The sodium salt was initially prescribed for its antipyretic and analgesic effects, but the salt was too irritating to the stomach, so a phenyl ester version was developed as a replacement. The esterified version passed successfully through the acidic stomach without irritation. It was hydrolyzed in the basic environment of the intestines,

    values were calculated based on these observations. They are shown in Table 2. Table 2. Rf Values Name Distance from Base to Center of Spot (cm) ÷ Distance from Base to Sovlent Front (cm) = Rf Value acetaminophen 4.0 ÷ 5.5 = .73 aspirin 4.7 ÷ 5.5 = .85 caffeine 2.4 ÷ 5.5 = .44 salicylamide 4.6 ÷ 5.5 = .84 Anacin 2.6 ÷ 5.8 = .45 Bufferin 5.0 ÷ 5.8 = .86 Excedrin 2.6 ÷ 5.8 = .45 4.3 ÷ 5.8 = .74 Tylenol 4.3 ÷ 5.8 = .74 Discussion

  • The Theory Of Green Chemistry On Microwave Heating Essay

    1532 Words  | 7 Pages

    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

    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

    develops (Ibuki T, et al, 1997; Celerier E et al, 2001). Non-narcotic analgesics are the household drugs used to treat moderate pains. These include paracetamol, aspirin and ibuprofen. There are very few noticeable effects beyond treating specific pains (in contrast to narcotics, when a feeling of well-being takes over the body). Aspirin (acetylsalicylic acid), a non-steroidal anti-inflammatory drug

    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

    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

  • Essay about Isolation of Components of Bc Powder

    1655 Words  | 7 Pages

    ! 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

  • The Chemical Ingredient Of Acetylsalicylic Acid Essay

    961 Words  | 4 Pages

    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
