N,N-diethylhydroxylamine

N,N-Diethylhydroxylamine (DEHA) is a chemical compound used primarily as an antioxidant and corrosion inhibitor. It is a clear, colorless to pale yellow liquid with a mild odor. DEHA is miscible with water, alcohol, and most organic solvents.

Chemical Structure

DEHA is an amine with the chemical formula (C2H5)2NOH. It consists of two ethyl groups attached to a nitrogen atom, which is also bonded to a hydroxyl group. This structure gives DEHA its unique properties as an antioxidant and corrosion inhibitor.

Production

DEHA is produced industrially by the reaction of diethylamine with hydrogen peroxide. This reaction is typically carried out in the presence of a catalyst to increase the rate of reaction.

Uses

DEHA is used in a variety of applications due to its antioxidant and corrosion inhibiting properties. It is used in the production of rubber, plastic, and resins to prevent oxidation and degradation of the material. In addition, DEHA is used as a corrosion inhibitor in boiler systems and in the production of photographic film.

Safety

DEHA is a mild irritant to the skin and eyes. Prolonged exposure can cause redness and irritation. Ingestion or inhalation can cause nausea, vomiting, and respiratory irritation. Proper personal protective equipment should be used when handling DEHA.

Environmental Impact

DEHA is not considered to be a persistent environmental pollutant. It is readily biodegradable and is not expected to bioaccumulate. However, it can be harmful to aquatic life in high concentrations.
