Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

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

It does nothing for the victims of crime‚ but perpetuates the idea of retribution‚ thus maintaining the endless cycle of violence in our culture.

Synthesis Module 5-6 Subject : Executive Development A. Summary of Report No business or strategy is good enough to succeed without strong leadership. Executives are often referred to as leaders. There are methods or techniques engaged by executives for their development. According to Peter Drucker‚ an effective decision making process must go through some basic steps. These steps will not “make” the decision – it will always be a judgement call – but if the steps are ignored

1.0 INTRODUCTION 1.1 Background of the Study Firstly‚ recycling is not a new concept to us‚ people has been doing it for thousands of years. Recycling is different from ‘re-use’ in the sense that re-use means using old products repeatedly. Recycling is the process of producing a new product from a recyclable material. Undeniably‚ recycling has always been a matter of helping the environment and for economic reasons. According to http://www.nural.com.my‚ in Malaysia‚ we produce 19‚000 tons

According to Figure 4 and 5‚ the moles of Cu initially obtained and at completion‚ differentiated. It was evident that the initial moles of Cu (0.0254)‚ did not regenerate all the amount‚ as 0.0124 moles of Cu was attained. In regards to this‚ the no. moles that was eliminated was approximately‚ 0.013. Respectively‚ in Figure 3‚ a large deviation amongst the initial and final quantity of copper‚ this implies that the rest of the mass that had diminished‚ was greater than the final product. These

Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination

Have you ever wondered why your voice matures when you get older? Well that’s because your vocal cords grow longer making you voice deeper. A male’s voice gets way deeper than a female’s voice though. A male’s larynx grows bigger during puberty making the voice deeper. For some people‚ if you sing‚ that means that your vocal range can increase easily. But if you don’t sing‚ it isn’t necessary for your vocal range to increase. As you grow older‚ your larynx hardens making your voice seem a little
