THEORY: The Diels-Alder cycloaddition reaction was discovered by Otto Diels and Kurt Alder and is very useful in the synthesis of polycyclic compounds. The Diels-Alder reaction can be described as: [4+2] cycloaddition- a diene with 4 π electrons + 2π electrons from the dienophile; a pericyclic concerted reaction- meaning the reaction occurs in a single step (no intermediates) and involves a cyclic redistribution of bonding electrons. In order for a Diels-Alder reaction to take place

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

Introduction A polymer is a large molecule comprised of numerous smaller molecules. It is possible for these large molecules to be linear‚ moderately branched‚ or highly interconnected. In the latter case the structure progresses into a large three-dimensional complex. The small molecules that serve as the basic building blocks for these large molecules are known as monomers (See Figure 1.1). An example of the relationship between a monomer and polymer is the commercially important material polyvinylchloride

Introduction: This experiment focuses on carrying out a Perkin Reaction to synthesize (E) and (Z) isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acid‚ acetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table

The global market for biosurfactants is expected to reach USD 2‚308.8 million by 2020‚ according to a new study by Grand View Research‚ Inc. Escalating consumer preference towards the use of bio-based products‚ particularly in Europe and North America is expected to increase biosurfactant penetration. In addition‚ stringent regulatory policies are further expected to augment the biosurfactant demand over the next six years. Methyl Ester Sulfonate (MES) was the largest consumed biosurfactant‚ accounting

Group Dynamics Within this essay I will reflect upon a specific issue of group dynamics that was experienced during a group exercise. Gibbs (1988) reflective model (Jasper‚ 2003. p.77) will be used to reflect upon the issue effectively and to set out the structure of reflection. Confidentiality and the GSCC code of practice will be kept to and maintained throughout this essay. The names of the people within the issues explained will be made up due to confidentiality.
