What is N,N-Diethylhydroxylamine used for?

N,N-Diethylhydroxylamine (DEHA) is primarily used as a polymerization inhibitor, oxygen scavenger, and corrosion inhibitor.

It has numerous industrial applications, including:

• Polymerization inhibitor: During the production, storage, and transportation of unsaturated monomers (such as styrene, butadiene, and vinyl chloride), DEHA effectively prevents spontaneous polymerization, improving product purity and stability.

• Oxygen scavenger: In boiler water treatment and oilfield injection systems, DEHA effectively removes dissolved oxygen from water, preventing corrosion of metal equipment.

• Corrosion inhibitor: In metalworking fluids, lubricants, and fuels, DEHA acts as a corrosion inhibitor, reducing corrosion on metal surfaces.

• Rubber and plastic stabilizer: DEHA acts as an antioxidant and light stabilizer, improving the aging resistance of rubber and plastic products.

• Pharmaceutical and pesticide intermediate: DEHA serves as an organic synthesis intermediate for the production of pharmaceuticals, pesticides, and other fine chemicals.
