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

Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the

Grignard Synthesis of Tirphenylmethanol David Szuminsky Organic Chemistry Lab II Shaopeng Zhang Monday 1PM 2/10/14 & 2/24/14 - Abstract A sample of triphenylmethanol was prepared using Grignard synthesis techniques. Reflux was used in order to speed up the reaction and the final product was purified using recrystallization methods. The percent recovery and percent yield were 80.46% and 47.526%‚ respectively. A melting point range of 85-87oC was obtained from

industrial settings due to the simplified synthesis and safety parameters of the overall reaction. Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is a fundamental and important synthesis process in training our future chemists in both commercial and academic employment and principles. By utilizing this method of synthesis‚ the chemist has the knowledge to utilize

Chris Archbold Argumentative Synthesis Prof. McKee 17 April 2013 Argumentative Synthesis on Skateboarding Skateboarding is a sport that is uniquely different from all others. It doesn’t require a team competing for a common goal. There isn’t a legitimate system that judges how talented a skateboarder is. There is no league regulating how skateboarding should be done. Skateboarding is an individualistic sport that provides infinite potential for progression. There is no limit on the amount
