Question

role of Na2Co3 in preparation of benzoic acid​

Answer 1

The explanation for the role of sodium carbonate is given below.

Explanation:

• Benzaldehyde is oxidized to benzoic acid which can easily hinder its desired reaction.
• Hence it is always recommended to use freshly distilled benzaldehyde for any work.
• We can remove the benzoic acid by the following methods:
• Simple bicarbonate treatment of benzaldehyde will remove all/any benzoic acid present.
• The sodium bicarbonate will neutralize the catalytic acid in this reaction.
• When benzaldehyde is kept in an inert atmosphere or oxygen-free atmosphere, it will definitely diminish the formation of benzoic acid. Also, the addition of an oxygen scavenger to the feed Benzaldehyde will help to lessen the formation of benzoic acid.
