What is Diethylhydroxylamine?
Diethylhydroxylamine (CAS 3710-84-7) is a hydroxylamine derivative used industrially as an oxygen scavenger, antioxidant and polymerization inhibitor.
Where is Diethylhydroxylamine used?
- Boiler feedwater and steam systems: scavenges dissolved oxygen to prevent corrosion in pipework and heat exchangers
- Metal passivator for long-term system integrity
- Polymer and monomer production: inhibits premature polymerization during storage and transport of vinyl and acrylic monomers
- Oil and gas processing: stabilizes hydrocarbon streams and protects refinery equipment from oxidative fouling
- Rubber and latex formulations: antioxidant that extends shelf life
- It intercepts free radicals and dissolved oxygen in process streams.
Commercial specifications
- Liquid, typically aqueous solution at 85% and 100% concentrations
- Technical grade, purity aligned to industrial requirements
- Packaging: drums, IBC totes, bulk tanker quantities
