Description

Diethylhydroxylamine , also known as CAS 3710-84-7 , is a versatile hydroxylamine derivative used industrially as an oxygen scavenger, antioxidant, and polymerization inhibitor. It intercepts free radicals and dissolved oxygen in process streams. This chemical protects equipment and materials from oxidative degradation across various industrial sectors. In boiler feedwater and steam systems, it scavenges dissolved oxygen to prevent corrosion in pipework and heat exchangers. The compound also acts as a metal passivator to ensure long-term system integrity. Polymer and monomer producers utilize it to inhibit premature polymerization during the storage and transport of vinyl and acrylic monomers. In oil and gas processing, it stabilizes hydrocarbon streams and protects refinery equipment from oxidative fouling. This ensures that process efficiency is maintained and downtime caused by equipment failure is minimized. Rubber and latex formulations incorporate this additive as an antioxidant to extend shelf life. It helps maintain product integrity through rigorous processing and long-term storage conditions in global supply chains. The product is supplied as a liquid, typically as an aqueous solution at concentrations of 85% and 100%. Technical grade is the standard commercial offering, with purity specifications aligned to industrial requirements. Packaging options for this chemical range from standard drums to IBC totes and bulk tanker quantities. This flexibility allows for efficient logistics and handling depending on the specific volume requirements of the facility. Contact us for supply of Diethylhydroxylamine Request Quote
