Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

Methods Using the China marker‚ I numbered test tubes 1-5 for identification purposes. Using a pipet I added 1 milliliter of each solution to it’s designated test tube. Next‚ I added 5 drops of the Biuret reagent to each test tube and agitated the mixture by shaking the tubes from side to side. After waiting 2 minutes I recorded the color of each mixture. I used the color
