Preparation of Phenyl benzoate
Preparation Method
Phenol is treated with benzoyl chloride in presence of sodium hydroxide for preparation phenyl benzoate.
Reagents
- Phenol 1 g
- Sodium hydroxide 1.5 g
- Benzoyl chloride 2 mL
Procedure
For the preparation phenyl bensoate, about 1 gram of phenol is dissolved in 15 mL of 10% sodium hydroxide solution in an Erlenmeyer flask. 2 mL of benzoyl chloride is added. Close the mouth of the flask with a rubber stopper and shake vigorously for about 30 minutes. When the reaction is complete, the smell of benzoyl chloride will disappear. The precipitated phenyl benzoate is separated by filtration, washed with water, dried and the yield is noted. A small quantity is recrystallized from alcohol. Determine the melting point of the product.
- Theoretical yield is approximately 2 grams
- The melting point of phenyl benzoate is 162 0C
