    Separting the Components of Panacetin

    The purpose of this experiment is to investigate the composition of a simulated pharmaceutical preparation Panacetin, a proposed type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Using techniques such as extraction, evaporation, and filtration, the three components will be isolated based on their solubilities and acid-base properties. The percent composition of Panacetin will also be deduced based on the masses of the three dried components; this is done to verify the composition attained is consistent with those listed on the preparations label. As a result of this investigation, my teammates and I allowed the Panacetin to undergo gravity filtration and separation techniques in order to identify whether there are any discrepancies in the components of the Panacetin. Furthermore, recrystallization and purification methods were used to determine if the unknown substance were similar in properties to either of the suspected unknown substances by comparing factors such as melting points to the chemical properties of phenactin and acetanilide. The results were as expected, based on the molecular weights and ratios of each separated chemicals, as well as the boiling point of the unknown it was determined that these ranges were close enough to indicate that the label is reasonably accurate in its composition. To add on however the identity of the unknown component differed from what the label indicated. In the end, the percentage composition attained based on our observations and yield confirmed that indeed the chemical composition of Panacetin were as indicated on the preparations label. The identity of the unknown component however suggested that the preparation did not contain acetaminophen as indicated, but instead was consistent with the chemical properties…

    Separating the Components of Panacetin

    Pre-Lab: Analgesic drugs are known for reducing pain, while antiseptic drugs reduce symptoms such as fevers and swelling. However, some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs, the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points, melting points and their solubility properties. To do this a chemist can also asses the differences between acidic and basic substances when they are added to water soluble mixtures. Within this current experiment I will asses the pharmaceutical preparation of Panacetin, by using it 's solubility along with other organic molecules. We know that Panacetin is made up of sucrose, aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning, we need a % recovery of 8-12% sucrose, 35-45% aspirin and 45-55% unknown.…

    Extraction and Evaporation. Separating the Components of “Panacetin”

    The problem proposed in the experiment is an unknown ingredient found in generic Panacetin tablets that must be discovered. Panacetin tablets are known to contain aspirin, acetaminophen, and sucrose; therefore, the tablets tested, containing aspirin and sucrose, are thought to contain an unknown of something similar to that of acetaminophen such as acetanilide or phenacetin. Another problem trying to be sought out in the experiments is whether or not the composition of Panacetin as stated on the label is accurate.…

    You'Re a Contract Painkiller

    In You Are a Contract Painkiller (1997, p. 111), author Maureen Littlejohn makes extensive use of personification to describe the functioning of Aspirin in our body, its various properties to fight pain, and its evolution over the years. Littlejohn describes how Aspirin claimed celebrity status as one of the world’s most popular, inexpensive painkillers by relieving headaches, sprains, blows, burns, swelling and fever. Furthermore, she added that Aspirin could also be used to reduce the risk of stroke and heart attack. The author supports the main idea by describing how the aspirin when taken with a modest stream of water or ginger ale, passed to the stomach through the esophagus and undergoes a series of chain reactions to disable the enzyme that converts the acid in cell membranes into prostaglandins (responsible for the pain). In a similar fashion it also helps bring fever down. Moreover, the author gives a brief history about the evolution of the modern day Aspirin from almost a thousand years ago when Hippocrates first discovered the property of willow leaves to help relieve pain. The author concludes the essay by highlighting the useful properties of Aspirin and the various ailments it provides relief from.…

    Aspirin Lab

    Aspirin is known as a pain reliever for muscle ache, head ache and can prevent heart attacks as well as blood clots, and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride reacting with Salicylic acid to produce Acetylsalicylic acid and Acetic acid (diluted vinegar). Aspirin is in millions of home today and in America, about 50 million tablets are consumed every day. When aspirin ages it breaks down and returns to the main chemicals that made the reaction.…
