    V. Results and Discussion One of the objectives of this exercise is to synthesize acetylsalicylic acid (aspirin) from salicylic acid. The mechanism for this synthesis is through nucleophilic acyl substitution. Acetic anhydride was the acetylation reagent used with the salicylic acid. The mechanisms and the reaction involved in the synthesis are seen in the following figure. 1.00 gram of fine white salicylic acid powder was weighed in a clean, dry 125mL Erlenmeyer flask. 3mL of strong smelling

    The chemical I will be looking at today is Aspirin. Aspirin is a medicine that was first produced 110 years ago. It came from salicylic acid found in plants such as the willow, and since then it has always been used. In 3000 BC the Egyptians used myrtle and willow to stop and reduce ones pains or fevers. In 30 AD Roman and Greek physicians discovered that the willow leaf could cure and help inflammation. There was one problem, the taste of the salicylic acid had a horrible taste causing vomiting

    Acetylsalicylic acid, or commonly known as “Aspirin” is widely used as a pain reliever, anti-inflammatory agent, and an antipyretic (fever reducer). Aspirin is a considered one of the most versatile drugs known to modern medicine. Aspirin’s active component, Salicylic acid, was initially isolated by Edward Stone. He isolated salicylic acid from the barks of a willow tree and derived from willow bark extracts. Salicylic acid is not used like it used to be because of the irritable effects it has

  • Thin Layer Chromatography Lab Report

    929 Words  | 4 Pages

    Thin Layer Chromatography (TLC) Abstract This experiment uses the TLC chromatography technique to identify the presence of acetylsalicylic and Acetaminophen in analgesic drugs (Tylenol and Anacin). It was found that the Anacin and acetylsalicylic had very closer Rf values (0.8 and 0.79). The Tylenol and acetaminophen had closer Rf values (0.54 and 0.58). Hence, Acetylsalicylic acid and acetaminophen were present in Anacin and Tylenol tablets respectively. Introduction Chromatography is the technique

    ABSTRACT: Pantoprazole sodium is an antiulcer drug. This compound inhibits gastric acid formation and thereby it is very efficient for the treatment of gastric and duodenum ulcers. But pantoprazole sodium is acid labile drug that will degrade in acidic environment of stomach resulting in therapeutic inefficacy. Hence it is necessary to bypass the acidic pH of the stomach which can be achieved by formulating delayed release dosage forms (single unit or multiple units) by using different enteric polymers

    The overall aim of our experiment was accomplished due to the fact that the compound produced was tested to be pure paracetamol. Its purity was tested by TLC, melting point range and NMR analysis. For the Melting Point Range Determination, samples of our re-crystallised p-aminophenol and paracetamol were placed into capillaries and into the melting point apparatus where data was recorded during the melt. Then, for the Thin Layer Chromatography, a TLC plate was prepared with four small dots loaded

    988 Words  | 4 Pages

    What is chelation therapy? Chelation (pronounced key-LAY-shun) therapy is treatment used in conventional medicine for removing heavy metals (including mercury) from the blood. It involves intravenous injections of a chelating agent, EDTA (ethylene diamine tetra-acetic acid), a synthetic amino acid. EDTA binds to heavy metals and minerals in the blood so that they can be excreted in the urine. Another intravenous agent used by some physicians for mercury detoxification is called DMPS (2,3-Dimercapto-1-propanesulfonic
