Lab 8- nitration of Methyl I Benzonate Date of experiment: INTRODUCTION: The nitration of methyl benzoate is an example of an electrophilic aromatic substation reaction. In the experiment the electrophile was the nitronium ion and the aromatic compound was methyl benzoate and with addition of nitrating solution Methyl 3-nitrobenzoate was the product. Methyl benzoate Methyl 3-nitrobenzoate MATERIALS AND METHODOLOGY: The procedures for this experiment

Santiago Horta‚ Daniella I School of Chemistry and Biochemistry‚ Georgia Institute of Technology Atlanta‚ GA 30332 Submitted: 18 February 2015 In this experiment‚ the product of a nitration will be purified by recrystallization using a selected solvent. Methyl benzoate is treated with nitric acid and sulfuric acid to obtain methyl 3-benzoate‚ which will be mixed with a solvent that will dissolve the product at its boiling temperature but not at room temperature. Comparing the melting point of both

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

Title: Nitration of Methyl Benzoate Objective: To prepare methyl-3-nitrobenzene from nitration of methyl benzoate. Results and calculations: Density = 1.094 g/ml = Mass of methyl benzoate = 1.094 g/ml x 2.8 ml = 3.0632 g no. of mol of methyl benzoate = = 0.022499 mol 1 mol of methyl benzoate produced 1 mol of methyl m-nitrobenzene. Therefore‚ 0.022499 mol of methyl benzoate produced 0.022499 mol of methl

a mixture of methyl benzoate and H2SO4. Percent yield for the final product was calculated followed by recrystallization and melting point was measured. Introduction: Nitration of Methyl Benzoate is one of the examples of Electrophilic aromatic substitutions. The use of a mixture of Sulfuric Acid and Nitric Acid is the classic way to make NO2+. The two main reaction types used for this are both substitutions: Electrophilic Aromatic Substitution and Nucleophile

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example
