Synthesis of Aspirin Ling Tecson Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order

INTRODUCTION Lactic Acid is an organic compound with the formula CH3CH (OH) COOH. Lactic is one of the types of fermentation which occur under anaerobic respiration to produce ATP without the use of oxygen. Anaerobic respiration takes place in certain prokaryotic organisms that have an Electron Transport Chain (ETC) but do not use oxygen as a final electron acceptor at the end of the chain (Campbell et all‚ 2015) different with the aerobic respiration which use oxygen to produce ATP and its final

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

Experiment 8: Synthesis of Adipic Acid Performed November 8th & 10th By Jennifer Seitz Organic Chemistry 344 Section 803 Fall 2011 Objective: The purpose of this experiment was to synthesize adipic acid from cyclohexanol via an oxidation reaction that was catalyzed by sulfuric acid. Purity of the product was assessed by measuring the melting point. Physical Properties/Structures: Name | Formula | Molecular Weight (g/mol) | Boiling Point (0C) | Melting Point(0C) | Density(g/mL)

IR ATR spectra of the solid complex was acquired along with a solution cell IR of the complex in methylene chloride. According to the lab manual used for this experiment two characteristic carbonyl IR stretches of MesMo(CO)3 occur strongly around 2000 cm-1. The stretches at 1940 and 1855 cm-1 in the IR ATR spectra are possible indicators of carbonyl stretches in the compound that was

experiment is to synthesis Banana oil by mixture of the isopentyl alcohol and acetic acid . Banana oil smells like fruit mostly it smells like banana. This reasons that this compound uses in different perfume products as well as the gums for the flavor. The reaction that takes place in this experiment is a esterification. In this experiment‚ the carboxyl group of the acetic acid joins with the hydroxyl group of the isopently alcohol‚ catalyzed by the presence of sulfuric acid‚ through a dehydration
