  • Description
  • Analysis


Diethyl hydroxylamine (DEHA) is an organic chemical compound derived from hydroxylamine, DEHA is a reducing agent that naturally is a yellow liquid. Diethyl hydroxylamine can remove oxygen well and act as an oxidizing agent. C4H11NO is the chemical formula of this organic compound.

DEHA appearance

Hydrazine is often used in power plants to eliminate the risk of corrosion caused by water-soluble oxygen. Diethyl hydroxylamine in boilers is one of the most important deoxygenating agents in operating conditions. The rate of oxygen removal at low temperatures is low, but this problem can be solved by adding hydroquinone as a catalyst.

This organic compound can be used as an inhibitory agent in polymerization processes, it also has anti-corrosion properties and can be used to protect metals from undesirable corrosion, and in the photography industry and the emergence of color, photos can be color stable.

DEHA chemical structure is as follows:

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.

Diethyl hydroxylamine toxicity:

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.

According to the reports and researches, DEHA has no special toxic effect unless it is in contact with the human body in the long run, in which case safety measures are recommended.


As mentioned, this substance is non-toxic, but it is necessary to observe safety tips when using it, avoid direct contact with the skin, and do not expose yourself to the gases caused by it, use glasses, special clothes, and masks. And avoid contact with your eyes and skin.
