CH3COOH + NH3 → CH3CONH2 + H2O
概要
Acetic acid reacts with ammonia to first form ammonium acetate, which upon strong heating loses water to form acetamide. The amide bond (C-N) is the same linkage found in proteins (peptide bonds). Direct thermal dehydration is energy-intensive; industrial methods use acyl chlorides or coupling reagents.
