Synthesis of n-Propyl Propanoate - we distilled/refluxed
Use a graduated cylinder to add the
following pure liquids to a 200 mL distillation
flask:
19.0 mL of n-propanol (0.25 mol)
18.5 mL of propanoic acid (0.25 mol)
Carefully add 5 drops of concentrated sulfuric acid and 2-4 boiling chips.
My questions:
What would the % yield of ester be if the reaction were simply allowed to equilibrate (i.e. no products are removed)?
Compare your experimental % yield of n-propyl propanoate to the predicted equilibrium yield. Were you successful in driving the reaction to the right?
My Data:
Volume of water collected: 4ml
Wt. of Flask + Product: 96.33
Wt. of Flask: 78.21
Wt. of product: 18.12
Equilibrium constant: approx 3
