Description

O,n-Diethylhydroxylamine is a versatile organic compound widely used as a highly effective oxygen scavenger and polymerization inhibitor. Its primary value lies in its ability to prevent unwanted oxidation and radical polymerization in sensitive chemical processes, thereby enhancing product stability and shelf life. This chemical is essential for industries such as polymer manufacturing, water treatment, and the production of specialty chemicals where precise control over oxidation and radical reactions is critical.

Application

• Polymerization Inhibitor: Used to prevent premature polymerization of monomers like styrene, acrylates, and vinyl acetate during production, storage, and transportation.
• Oxygen Scavenger in Water Treatment: Effectively removes dissolved oxygen from boiler feedwater and other industrial water systems to prevent corrosion.
• Stabilizer for Fuels and Lubricants: Inhibits oxidation and gum formation in hydrocarbon-based fuels and lubricating oils, extending their usable life.
• Chemical Intermediate: Serves as a key building block in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals.
• Photographic Developer: Acts as a reducing agent in photographic developing solutions.
• Corrosion Inhibitor: Protects metal surfaces in closed cooling systems and other industrial applications.

Quality Control

Our O,n-Diethylhydroxylamine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, water content, and impurity profiles. We ensure compliance with relevant industry standards and can provide material tailored to specific customer requirements, including technical and high-purity grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep containers tightly sealed under a nitrogen blanket and at temperatures not exceeding 25°C (77°F). Keep away from strong oxidizing agents.
