DEHA – Diethylhydroxylamine for Water Treatment
Chemical Name: N,N-Diethylhydroxylamine (DEHA) CAS Number: 3710-84-7 Molecular Formula: C₄H₁₁NO Molecular Weight: 89.14 g/mol Product Category: Boiler Water Treatment / Oxygen Scavenger / Corrosion Inhibitor
Product Description
DEHA (Diethylhydroxylamine) is an organic, volatile oxygen scavenger widely used in industrial boiler water-treatment systems to control dissolved oxygen and minimize oxygen-induced corrosion.
DEHA reacts with dissolved oxygen in boiler feedwater and helps protect boiler internals, feedwater lines and condensate return systems.
Unlike conventional sodium sulfite oxygen scavengers, DEHA does not introduce dissolved inorganic salts into boiler water. This makes it useful in appropriately designed high-pressure boiler treatment programs where controlling dissolved solids is important.
Application
It is use for Water Treatment Chemical, Corrosion Inhibitor, Polymerization, Photographic Chemicals, Decolourisation, etc.
DEHA used as a volatile oxygen scavenger and reacts in a ratio of 2.8/1 DEHA/O2.

Precautions
Diethylhydroxylamine (DEHA) is an organic compound with the formula (C2H5)2NOH. It is a colorless liquid, although it is usually encountered as a solution. It is mainly used as an oxygen scavenger in water treatment. It is a volatile oxygen scavenger and reacts in a ratio of 2.8/1 DEHA/O2. It is employed in high pressure (>70 bar) boiler systems due to a very low rate of reaction at low temperatures and pressures. Due to its volatility, it acts as an oxygen scavenger throughout the entire boiler system due to steam carryover. DEHA also reacts with ferrous metals to form a passivized film of magnetite throughout the boiler system.
