i am required to obtain a very pure ester. so i carry out synthesis, isolation and the distillation. during distillation, i will be distillating alcohol and ester. in my case, i used 1-butanol and ethanoic acid to produce butyl acetate. butanol has a lower boiling point thus it will condense first. this will contaminate the condenser with butanol and thus the ester that i will obtain will not be pure. can i wash away the butanol using water just like in isolation or is there any other way to obtain a pure ester.
