UNIVERSITY OF WATERLOO Department of Chemistry Synthesis of ACETAMINOPHEN Laboratory Report 1 CHEM 123L January 19‚ 2014 Prepared for: Dr. S. Stathopulos Department of Sciences‚ Chemistry Faculty University of Waterloo Teaching Assistant: Aaron Chan Prepared by: Section 001 Vithurjan Satkunarasan 20495383 Lab Partner: Ken Xu Introduction The synthesis of Acetaminophen is based on the amine group of p-aminophenol being acetylated by acetic anhydride to form an amide functional group

synthesised is only 67%-70% and a maximum 70% yield of ester usually is not considered to be acceptable for a synthesis reaction‚ instead it is considering as a poor yield of ester. The synthesised ester can only have a maximum yield of 70% because for ester in which the carboxylic acid and alcohol are sterically unhindered‚ a same ratio mixture of carboxylic acid and alcohol can only synthesis ester with a maximum yield of 70% ester as the reaction with the same ration of mixture will reach a state

Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could

Synthesis As a representation of the culture of the time period‚ art enables its audience a sense of history and recollection. The pieces of work are timeless‚ precious‚ and irreplaceable‚ for they hold a significance that amazes all. Therefore‚ a museum that houses a collection of artifacts have employees who bear the responsibility of accurately securing and displaying works of arts or artifacts. When doing so‚ it is imperative for the these group of people who have the weight of the artifact’s

Period 6 March 21‚ 2012 Synthesis Essay Conformity versus individualism is a topic that has been discussed in literature throughout the years. When people are forced to conform to society‚ they are expected to act appropriately toward society’s vision. When people stand out from the crowd‚ they create an imbalance in culture. This is why individualism is condemned in most works of literature‚ but people still attempt to defy society’s vision and make a difference. This topic is discussed

Assignment 37: Synthesis Essay As Martin Buber holds “relationship of supreme importance‚” we must hold relationships and people of supreme importance. (Littlejohn & Domenici 2007‚ p. 243). People are not objects “to be changed‚ reduced and manipulated.” (Littlejohn & Domenici 2007‚ p. 243). When we start treating people as objects we are building the I-It relationship with them. (Littlejohn & Domenici‚ 2007). This type of relationship fails to move towards value because people feel mistreated

Synthesis Essay Prompt #1 Throughout history‚ primary sources such as diaries‚ postcards‚ and letters have all been utilized to their full extent. These were used to document events in the past‚ to which the present can achieve a better understanding of. However‚ some texts have more influence over another‚ to which the ineffectual documents are discarded. Historical texts such as the Declaration of Independence‚ or the Holy Bible are all preserved because of their role in fabricating today’s society

Response Paper #1: Minimalism Synthesis While the idea of an American Dream has been around for many years and transformed through time‚ it has overwhelmingly remained the same at its core. Generally‚ people want to be successful‚ have a job‚ be comfortable‚ live a long and relatively stress-free life‚ all with their most important possessions. The fact is: this looks different to everyone. Some people may want a mansion on a lake with a boat‚ while some may want a cozy home with kids‚ and others
