acidification of salicylic acid and acetic anhydride. The objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore‚ the other objectives were to enable students to conduct the synthesis of aspirin‚ reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining

Introduction According to the WHO (2010)‚ childhood obesity is one of the most serious public health challenges of the 21st century. Globally‚ in 2010 the number of overweight children under the age of 5 is estimated to be over 42 million (WHO‚ 2010). Obesity can be defined in a number of ways‚ e.g. by population means‚ BMI and waist circumference (Odgen‚ 2012). And according to Kleiser et al (2009)‚ obesity may have several short-term consequences (e.g. social discrimination‚ lower quality of

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

Obesity in children is a common issue that exists in developed and developing countries. Although obesity affects children’s health‚ levels are still increasing. Nutrition specialists have claimed that it is due to the increase in fast food chains and a lack of education in schools.However‚ inspiring the younger generation to live a healthy lifestyle and encouraging parents to keep their children healthy may help. This essay will explore two strategies which could decrease the levels of obesity in

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 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

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
