How to prepare methyl benzoate?
- CHM230 - Preparation of Methyl Benzoate Procedure A. Reflux 1. Add 0.1 mole of benzoic acid to a 100 mL round bottom flask. 2. Add 40 mL of methanol 3. Add 3.0 mL of concentrated sulfuric acid 4. Mix all reactants and add boiling stones 5. Attach a water cooled reflux condenser 6.
What is the mechanism of nitration of methyl benzoate?
- This is the mechanisms of for nitration of methyl benzoate: Result and observation Melting point for 1st= 75?C - 78?C 2nd= 76?C - 78?C From the literature boling point which is melting point for methyl m-nitrobenzoate whic is 78-80?C, we can conclude that the product that we get is methyl m-nitrobenzoate.
How much methyl benzoate was recovered from the Fischer esterification process?
- As a result of the Fischer esterification process, 0.344 g of methyl benzoate was recovered for the final product. The calculation for the yield obtained by the synthesis is provided below (3): The synthesizing of methyl benzoate from benzoic acid and methanol was a successful endeavor.
What is the final yield of methyl benzoate?
- We recovered 0.344 g of the final product (methyl benzoate) for a 15.46% final yield. Methyl benzoate has a boiling point of 199.5 degrees Celsius and a molecular weight of 136.15 grams per mole (3). With a boiling point this high, it was important to reflux for the entire hour.
