Amber Klein Nitration of Methyl Benzoate Problem: What isomer will the major product, methyl nitrobenzoate, of the nitration of ester methyl benzoate be: ortho, meta, or para? How to Solve: Nitration will be carried out on the aromatic ester methyl benzoate. From this, the position of the electrophilic substitution of the (COOCH 3 ) substituent directing group can be determined. The major product of the nitration will be isolated and the melting point will determine the position of the isomer to be ortho, meta, or para. Hypothesis: The product will be methyl m-nitrobenzoate. The melting point should be close to 78 to 80°C. Materials: 6 mL of concentrated sulfuric acid 3.0 g of methyl benzoate 2 mL of concentrated nitric acid and 2 mL of sulfuric acid mixture 25 g of crushed ice ice –cold methanol administered in 5 mL increments Pre-Lab Calculations: Overall Reaction: Nitrating Methyl Benzoate Mechanism: Observations: 6 mL of concentrated sulfuric acid is cooled to 0°C in an Erlenmeyer
