Description

N,n-Diethylhydroxylamine (DEHA) is a versatile organic compound primarily valued for its potent reducing and antioxidant properties. Its ability to effectively scavenge oxygen and inhibit radical polymerization makes it a critical performance additive in several high-value industrial processes. This chemical is essential for manufacturers in the polymer, water treatment, and photographic industries seeking to enhance product stability and process control.

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.
• Photographic Developer: Acts as a developing agent and antioxidant in color photographic processing solutions.
• Chemical Intermediate: Serves as a building block in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.
• Fuel & Lubricant Additive: Functions as an antioxidant and stabilizer in fuels and lubricating oils to extend shelf life and performance.
• Corrosion Inhibitor: Protects metal surfaces in closed-loop systems by passivating the metal and neutralizing corrosive agents.

Quality Control

Our N,n-Diethylhydroxylamine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed-upon standards.

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 highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
