Question

After the synthesis of butyl acetate was completed, the reaction was transferred into a separatory funnel to be extracted with water?

1) Why was water used as the solvent for extraction?

2) Which layer is the top layer and what product does it contains?

3) Which layer is the bottom layer and what unwanted product does it contains?

4) Why was sodium carbonate used to wash the organic layer in the separatory funnel?

the reaction of acetic acid with 1-butanol to give n-butyl acetate.

Here water is biproduct. hence water will be used as the solvent for extraction to remove water from reaction medium.

organic layer will be top it will contain n-Butyl acetate.

water layer will be bottom which contains water from reaction medium and excess acetic acid

sodium carbonate is used to remove the trace amount of acid from organic layer
