Diethylhydroxylamine (DEHA) with the formula (C2H5)2NOH is a colorless or yellow liquid with an amine-like odor liquid. it is an inorganic compound that usually used as an oxygen scavenger in water treatment. DEHA an alternative oxygen scavenger to hydrazine and sulfite.
Its unique combination of properties, such as volatility; the ability to passivate steel surfaces; and its very low toxicity makes it the oxygen scavenger of choice for many applications

- Corrosion inhibitor
In oxygen scavengers in boiler DEHA was an alternative to hydrazine Which has very low toxicity and neutralizes amine fluctuations Like hydrazine.
DEHA minimizes system corrosion by forming a passive magnetite film on low carbon steel surfaces.
The main purposes of boiler water treatment are to prevent the scale formation and corrosion of the internal surfaces of the system.
Minimize corrosion in the boiler involves the removal of all traces of oxygen from the boiler feed water and creates the conditions for a passive magnetite film to form in it.
another key advantage of DEHA is volatility. not only does DEHA destroy oxygen and it becomes passive
It also comes out of the boiler to completely protect the metal system in the feed and other parts.
Comparison of the performance of DEHA and hydrazine
In terms of oxygen inhibition, 40% more DEHA is required than hydrazine (N2H4).
The competitive advantage that DEHA has over hydrazine is due to fluctuations and Toxicity is low.
The LD50 for hydrazine is 82 mg/kg on rats and 91mg/kg on rabbits.
The same LD50 numbers for DEHA are 2190 mg/kg on rats and 1300 mg/kg on rabbits
Toxicity of Diethylhydroxylamine
DEHA is not approved by the Food and Drug Administration (FDA), therefore, it cannot be used in systems related to food production.
The toxicity of DEHA is very low. LD50 numbers for DEHA are 2190 mg / kg in rats and 1300 mg / kg in rabbits. These Dose rates are very high.
