Nitration of Methyl Benzoate Introduction: Nitration is an example of an electrophile aromatic substitution reaction‚ where nitro (NO2) group is being substituted for a hydrogen on an aromatic compound. This is achieved by the formation of the nitronium ion by protonation of nitric acid from sulfuric acid. The zirconium ion is a strong electrophile and can react with aromatic compound such as Methyl benzoate to form an arenium ion intermediate. The arenium ion is then depronated to reform

The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

nonpolar organic phase. Benzoic acid‚ C7H6O2‚ is a white crystalline solid and a simple aromatic carboxylic acid with a faint‚ pleasant odor. Its molecular weight is 122.12 g/mol. It is very slightly soluble in cold water‚ soluble to acetone and benzene‚ and very soluble to ether and ethanol. Its solubility in water is 1.9 g/L at 0°C and 68 g/L at 95°C. It has a density of 1.2659 g/cm3 at 15 torr and has a melting point of 122.4°C. It has a boiling point of 249.2°C. Figure 1. Structure

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
