EXERCISE 11 Synthesis of Aspirin (Acetylsalicylic Acid from Salicylic Acid) RAQUID‚ Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound

Reshmi Nair Title: Determination of Aspirin through back titration. Aim: To determine the concentration of Aspirin in a tablet using NaOH and Hcl. Research Question: What is the concentration of Aspirin in a normal tablet? Background: Aspirin is the general name for acetylsalicylic acid (ASA); it is also the trademark of the drug produced by Bayer in Germany. In eighty countries‚ aspirin is a registered trademark‚ but in other places the term aspirin refers to ASA by itself or as an ingredient

Biol 2402 NAME ______________________________ CASE STUDY FOR LAB TEST 2 SECTION ____________________________ Raymond‚ a 50 yo pilot‚ was working a transatlantic flight when he noticed an uncommon stiffness and pain in his left leg. Upon rubbing the area he noticed it felt hot. He had played touch football the day before so he passed it off as soreness or a bruise. He also remembered that he had been stung by a bee during the match and that area was also red and swollen with a hard knot

Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

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

the percentage composition of the label (50% paracetamol‚ 40% aspirin and 10% sucrose) matches that of the percentage composition of the powder by following 10% ranges of each component in the powder. I am going to do this via a number of methods including vacuum filtration‚ heating‚ extraction and evaporation. Experimental method: The experiment was done in three parts: firstly the separation of sucrose‚ then the separation of Aspirin and the isolation of the unknown component. 1. Separation
