Butanoic Acid is made from heating butan-1-ol with Acidified Potassium dichromate and refluxing for 30 minutes of so. The potassium Dichromate changes from orange to green as it is reduced and the alcohol is oxidised. After the reaction is complete then the apparatus is changed and set up as in the photograph to allow the butanoic acid to be distilled off from the mixture leaving the chromate behind and the butanoic acid is collected in the conical flask.
