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 with HCl and

Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon‚ hydrogen and oxygen. The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin‚ the

Synthesis Conclusion: Conclusion: As we can see‚ the sources show us that during the Enlightenment period money was very important. It shows that during the time people would do merely anything for money‚ even force their children into arranged marriages or‚ as Voltaire suggest satirically‚ sell them as a food source. Parents or even the brides and grooms themselves would arranged marriages for economic gain. This was not always the case. We have learned from She Stoops to Conquer that‚ although

U‚ and C for the nucleotides guanine‚ adenine‚ uracil and cytosine) that directs synthesis of specific proteins‚ while many viruses encode their genetic information using an RNA genome. Some RNA molecules play an active role within cells by catalyzing biological reactions‚ controlling gene expression‚ or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis‚ a universal function whereby mRNA molecules direct the assembly of proteins on ribosomes

The first synthetic sweetener‚ saccharin‚ was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately seven years after it’s discovery‚ J.D. Reidel‚ of Berlin‚ was able to synthesis Dulcin at a reasonable cost. Once it became possible to synthesis at a reasonable cost‚ mass production of the sweetener began. Dulcin was favored over its competitor‚ Saccharin‚ because it did not possess a bitter aftertaste. For a very brief period of time Dulcin was marketed

Synthesis of Aspirin Name: Xuanyi Li Teaching assistant: Deirdre Zwilling November 15‚ 2009 Purpose: To synthesize aspirin‚ a common analgesic drug‚ via nucleophilic acid-catalyzed substitution reaction of salicyclic acid with acetic anhydride. The whole reaction is catalyzed by phosphoric acid. (The experiment involved three parts: The synthesis of aspirin‚ the isolation and purification of aspirin‚ and the estimation of the purity of the final product.) [pic] Procedure[1]: A mixture

EXERCISE 11 SYNTHESIS OF ASPIRIN MARAVILLA‚ Ana Mikaela B Group 4 CHEM 40.1 1L Date performed: September 30‚ 2013 Date submitted: October 7‚ 2013 VI. RESULTS AND DISCUSSION Aspirin is prepared by the esterification of salicylic acid with acetic anhydride under acidic conditions. The phenol group in salicylic acid is replaced by a carboxyl group through electrophilic substitution. The mechanism for the reaction can be summarized
