The Effect of the Different Forms of Acetaminophen on Solubility
Abstract Some consumers want to know if acetaminophen dissolves faster in the form of tablets, gelcaps, or caplets in order to get the fastest pain relief. The purpose of this experiment was to find out which of the three tested forms of acetaminophen would dissolve the most over a time period ten minutes. The hypothesis stated that the tablets would dissolve the most over the ten minutes. The hypothesis was tested by dropping ten of each of the forms of the acetaminophen into two thirds a cup of boiling water and observing how much each had dissolved after ten minutes. The data collected supported the hypothesis and the tablets were significantly more dissolved than the gelcaps and caplets. This experiment could be changed by having a component stir the acetaminophen and the water together.

Introduction The solubility of medicine is important because the quicker it dissolves, the quicker is can start working. There are many different forms of Acetaminophen on the market. This experiment is an attempt to discover which form of Acetaminophen will dissolve the quickest and most complete. Acetaminophen was accepted for use by the Food and Drug Administration in 1951 (Ogbru 1). It is an analgesic, or a drug that helps relieve a person of aches and pains (Ogbru 1). Acetaminophen is also an antipyretic, which are drugs that lower a person’s elevated body temperature (Ogbru 1). These kinds of drugs are used by many people everyday. Acetaminophen is a compound including: Carbon, Hydrogen, Nitrogen, and Oxygen (Acetaminophen 1). The molecular formula is C8H9NO2 (Acetaminophen 1). N-(4-Hydroxyphenyl) acetamide is the chemical name of Acetaminophen (Acetaminophen 1). Paracetamol, Tempra, and Tylenol are some of the other different brand names used for it (Acetaminophen 1). Acetaminophen is described as a white, odorless powder (Acetaminophen 1). Solubility is the capability of one substance to be dissolved by another (Butt 587). Acetaminophen is a soluble compound; it

    The purpose of this experiment was to create and obtain pure acetaminophen. p-aminophenol and acetic anhydride were used to create acetaminophen and acetic acid. The acetic acid mixed with acetaminophen created an impure sample, which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure sample was 76%. The melting point of the pure sample was 167C - 169C.…

    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. Once separated, the components extracted were characterized by measuring the melting point and performing a TLC analysis. Also, the recovered aspirin from the first part of the experiment was recrystallized and compared to that of the isolated aspirin.…

    The second experiment of the semester focuses on separating and identifying the components of Panacetin, which is a common medication that relieves pain. The label reveals that Panacetin is composed of sucrose (10%), aspirin (40%), and Tylenol (50%). Although this information is reported, the true composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin, Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable in identification of the unknown component, as well as the true percent composition of each component 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…

    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.…

    The unknown in this experiment is presumed to be something similar to acetaminophen, such as acetanilide or phenacetin. Recrystallization and melting point temperature were used to help identify the unknown in Panacetin. Recrystallization removes impurities as a substance goes through physical transformations from a solid to a liquid and back to a solid. As the solid reforms as a crystalline structure, it does so without incorporate any impurities that may have been present in the initial substance. Pure substances have specific melting points that can assist in identification. However, if the substance is not pure, the melting point will be lower than expected. The substance will also have a wider melting point range.…

    Although the acetanilide and aspirin are both quite insoluble in water at room temperature, the sodium salt of aspirin is very soluble in water but insoluble in dichloromethane. Because aspirin is a reasonably strong acid, it can be converted to the salt, sodium acetylsalicylate, by reaction with the basic sodium hydroxide. While the two layers are thoroughly mixed, the aspirin will react with the sodium hydroxide in the bottom layer, which then migrates to the aqueous layer and can be easily separated in a separatory funnel. Adding some dilute hydrochloric acid to the aqueous solution restores free aspirin as an insoluble white solid; evaporating the solvent from the bottom layer leaves the acetanilide behind.…

    Acetaminophen is a common analgesic used to treat mild pain. We synthesized acetaminophen by reacting p-aminophenol and acetic anhydride. The amine group on the p-aminophenol reacted with the center oxygen atom on the acetic anhydride to form an amide. We reacted 0.210g of p-aminophenol with 0.240ml of acetic anhydride in the presence of heat, and then cooled the solution in an ice bath until crystals formed. The solid acetaminophen was filtered from the solution and then subjected to a recrystallization using a 50:50 water-ethanol solvent. 0.1484g of crude acetaminophen was measured and after purification 0.0669g of pure acetaminophen was collected. A percent yield of 23% was calculated from our theoretical and actual yield. The melting point…

    We used this specific eluent because it is polar. Since the analgesics used in this lab contained different functional groups, some were more polar than others. So, the polar eluent with a non-polar TLC plate assists in illustrating the different polarity strengths and determining the analgesic drugs in a mixture. Furthermore, the acetic acid component of the eluent used helps remove the excessive Ibuprofen and Acetylsalicylic Acid. This is done by restraining their ionization. Overall, ethyl acetate containing 0.5% acetic acid was effective because the various analgesics in Anacin, Excedrin, Motrin, and No-Doz were all clearly separated and…

    Vicodin is prescription medication that is used to treat moderate to severe pain in adults. The two main ingredients in Vicodin are Hydrocodone bitartrate and acetaminophen. Hydrocodone is considered to be a pain reliever that acts similarly to codine and is effective at decreasing the pain as well as relieving cough, however its can also cause drowsiness, mood changes, and metal “clouding”. Because of this reason the it can only be used when combined with another drug and not alone, as far as in the United States. Therefore its combined with acetaminophen, which is also a pain reliever along with a fever reducer. The combination of these two drugs helps improve acetaminophen’s effectiveness at relieving pain as well as limiting the potential abuse of Hydrocodone. The maximum dose of Vicodin is usually controlled by the amount of acetaminophen that it contains.…
