Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol

Synthesis of Benzanilide and Methyl 3-Nitrobenzoate and the Identification of ‘Unknowns’ from Spectroscopic and Physical Properties James Lucas 10394308 23/11/12 Introduction In this series of practicals it was the aim to synthesise both Benzanilide and Methyl 3-Nitrobenzoate. Benzanilide was synthesised using The Schotten Baumann reaction which takes a hydrogen atom from an amino group and substitutes it for an acyl group. For Methyl 3-Nitrobenzoate‚ NO2+ was used as an

Chapter 28 Review 1. How did the Philippines become a major headache for America? Filipinos erupted into an open insurrection in 1899 under Emilio Aguinaldo. The war/ conflict was sordid and prolonged. Instead of quietly assimilating‚ they objected. 2. Why did the United States hold on to the Philippines? Millions of American dollars were invested in improving the nation’s infrastructure and education. Moreover the 2 nations had established important economic ties including trades in sugar

Nitration of Methyl Benzoate Purpose: The purpose of this experiment was to synthesize methyl m-Nitrobenzoate from methyl benzoate‚ concentrated HNO3‚ and concentrated H2 SO4 by an electrophilic substitution reaction. The H2 SO4 and the HNO3 were initially combined to form nitronium ion which was then used as an electrophile in the reaction. Crystals that were collected after the formation of the methyl m-Nitrobenzoate were collected by vacuum filtration and the product was isolated and purified

Experiment #1 – Aromatic Nitration The purpose of this lab is to convert toluene to nitrotoluene through the process of aromatic nitration. This is done by electrophilic aromatic substitution. The aromatic organic compound‚ toluene‚ is reacted under mild conditions with an electrophile‚ the nitronium ion‚ resulting in a product of nitrotoluene. Failure to use mild conditions may result in polynitration. Different reaction conditions were studied to understand the effect of nitrating agent
