4-Chlorobenzaldehyde + KOH,H+ >> 4-Chlorobenzyl alcohol +4-Chlorobenzoic acid
Purpose: This research demonstrate the simultaneous oxidation and reduction of an aromatic aldehyde to form the corresponding benzoyl alcohol and benzoic acid.
1. In this research, the alkaline phase was diluted with the water. Then it was acidified by determined the hydrochloric acid. Explain the acidification the phase of alkaline. How which manner it help in isolation of carboxylic acid product? Discuss this point in a detail.
2. The possibility of the alcohol product reacting with the methanolic KOH. Why would this effect the cleanliness of the acid product? How which manner you describe if your acid product was contaminated in this way?
