This organic compound is a mono-substituted amide.[2] Organic compounds of the amide group can react in many different organic processes to form other useful compounds for synthesis.
Propanamide can be prepared by the condensation reaction between urea and propanoic acid:
- (NH2)2CO + 2 CH3CH2COOH → 2CH3CH2CO(NH2) + H2O + CO2
or by the dehydration of ammonium propionate:
- (NH4)CH3CH2COO → CH3CH2CONH2 + H2O
Propanamide being an amide can participate in a Hofmann rearrangement to produce ethylamine gas.
