Experiment 1 Synthesis of Acetaminophen Clifford Tse 20529845 Partner – Raminder Dhanoa TA – Xiao Qi CHEM 123L - 012 February 6‚ 2014 Introduction Acetaminophen‚ also commonly known as Tylenol‚ is an over-the-counter medicine used to relieve pain and reduce fevers. Within this experiment‚ Acetaminophen will be formed through the reaction between p-aminophenol and acetic anhydride. This reaction will incur Acetaminophen as a crude solid being impure‚ which will be purified further through

Introduction: Acetaminophen is a commonly used analgesic‚ which is essentially just a medicine that relieves pain (Prescott‚ 2000). Acetaminophen is created by synthesizing p-Aminophenol with Acetic anhydride. This reaction occurs when the amine group of the p-aminophenol is acetylated by the acetic anhydride. The resultant is an amide functional group (Ellis‚ 2002). However‚ the product that is obtained from this product is a crude solid which cannot be used as an analgesic and therefore the crude

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

Small samples of acetaminophen‚ acetylsalicylic acid‚ cellulose‚ starch‚ and caffeine were obtained. These samples were then placed into seperate sets of test tubes that contained water‚ acetone‚ or dichloroethane. Solubilities were then tested for each sample in each solution which can be seen in Table 5. Next‚ four random pills were obtained and weights were taken of each. Each of the pills were grinded up using a separate mortar and pestle. The grinded up pills were then weighed. The grinded

Reformist Clinton: Pioneering Women’s Rights Revolution In September 1995‚ then-First Lady of the United States‚ Hillary Clinton delivered a riveting speech on Women’s Rights before the Fourth World Conference on Women in Beijing. She hosted delegates around the world‚ creating a Platform of Action to achieve greater equality and opportunity for women. This immensely assertive speech stood out amongst others in that period as it was hosted by a prominent female leader in the ‘capital of a brutal

Situation 1: The motorcycle helmet market has 13 companies‚ and four firm concentration ratio of 26%. While the helmets have a variety of designs‚ they are sold at very similar prices. Recently‚ the death rate from head injuries in motorcycle crashes has been rising. The producers advertise their helmets as “effective‚” but some helmets withstand most falls and others are produced with materials that are more likely to crack in commonly experienced falls. The weaker helmets cost about $8 less to

Experiment 3: The preparation of acetaminophen (paracetamol) with thin layer chromatography (TLC) to monitor the reaction. Abstract: This experiment is to demonstrate the preparation of paracetamol and its properties. Reflux and filtration of 4-aminophenol and acetic anhydride formed the crude sample. Further analysis of dry white crystals were used to give quantitative measurements and a percentage yield of 46% was obtained. The overall conclusion is that the acetic anhydride reacted with the
