Date of Experiment: September 10th‚ 2013 Organic Chemistry II – CHLB330 Name: Symone E. MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

Contents 1.0 Abstract Acetaminophen and aspirin are both well-known drugs that relieve pain and reduce fever. This report looks at acetaminophen as a potential substitute for a patient who is allergic to aspirin. Acetaminophen‚ a common analgesic drug that can be bought over the counter‚ was synthesised by Hormon Northrop Morse. With acetaminophen consisting of a benzene ring‚ an amide and an alcohol group‚ it has the ability to stop pain and reduce fevers. However‚ due to the state of technology

Drinking from water with a TDS higher than 500 mg/l may cause severe harm to one’s health. Hypothesis Statement: Sharjah taped water has a TDS above than 500 mg/l.

to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction Aspirin is a medicine commonly found in households around the world. It also is one of

is an acid-catalyzed reaction of an alcohol and carboxylic acid. One of the esters known for its characteristic banana flavor is the isoamyl acetate. By using Fischer reaction‚ Isoamyl acetate was produced by refluxing isoamyl alchol and acetic anhydride with the presence of sulfuric acid for 30 minutes. After cooling the mixture‚ cold water was added and it was transferred in a separatory funnel. It was then extracted with immiscible saturated sodium bicarbonate to hasten separation. The sodium

Technical grade aniline was reacted with acetic anhydride to give acetanilide a dark brown color‚ due to the presence of impurities. Crystallization of the crude product from water was combined with decolorization with activated carbon‚ furnished pure acetanilide as white flakes‚ melting point 112-115°C‚ yield 70.3%. Experimental: 2 grams of technical grade aniline and 15ml water were placed in a 125ml Erlenmeyer flask. Then‚ 2.5ml of acetic anhydride was added while swirling the flask. An exothermic

Case Study: Thyroid Storm Tammy is a 33 year old white female found by her fiancé to be confused‚ agitated‚ diaphoretic‚ and incontinent of diarrhea stool. The patient was brought into the ED by her fiancé for evaluation. Her fiancé states he is concerned because he thinks the patient has the flu because she has had a fever‚ nausea‚ diarrhea and diaphoresis that have progressively gotten worse over the past 24 hours.

The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing to the experiment is being able to determine and distinguish what moles have evolved thus being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction. Procedure Step 1: Obtain a 600 mL beaker‚ and add 300 mL of water. Step 2: Add 30 mL of HCl (2M) to the beaker‚ and stir. Step 3. Add 10 mg of magnesium metal to the beaker. Step 4. Allow
