Propanamide has the chemical formula CH3CH2C=O(NH2). It is the amide of propanoic acid. This organic compound is a mono-substituted amide. Organic compounds of the amide group can react in many different organic processes to form other useful compounds for synthesis. Preparation Propanamide can be prepared by the condensation reaction between urea and propanoic acid: (NH2)2CO + 2CH3CH2COOH -> CH3CH2CO(NH2) + H2O + CO2 or by the dehydration of ammonium propionate: (NH4)CH3CH2COO -> CH3CH2CONH2 + H2O Reactions Propanamide being an amide can participate in a Hoffman rearrangement to produce ethylamine gas.
