stability
1. Chemical properties: Two forms of salt can be formed by interaction with hydrogen chloride, namely CH3CONHCH3·HCl(melting point 67.2 ~ 69.4℃) and (CH3CONHCH3)2·HCl. It barely reacts with metallic sodium at room temperature. It reacts with nitrite to form nitroso compounds. Reflux boiling with acetic anhydride produces N-methyl diacetamide. N- methyl acetamide can be hydrolyzed by either acid or base.

2. It exists in smoke.
