    Abstract: A method for preparing amides by reacting a vicinal nitroketone with ammonia, a primary amine or a secondary amine at a temperature of from about 60* to about 130*C. The amides so prepared are useful as foam stabilizers, waterproofing agents, rust inhibitors, fuel oil additives, antistatic compounds, viscosity controllers, cosmetic components and high-temperature solvents.
