Production

It is produced from the reaction of triethylamine and peroxide as the starting material and then purification and distillation.

Applications

  • Oxygen scavenger for medium and high-pressure boilers.
  • radical scavenger in polymerization
  • Electronic chemicals: in the microelectronics industry, DEHA is used to remove light resistance from microelectronic components.
  • Photographic chemicals: In the photography industry, DEHA is mixed with other chemicals to create the right color
  • Polymer processing
  • Upstream O&G-production
  • Water treatment industrial
  • Polymerization inhibitor
  • Color stabilizer
  • Discoloration inhibitor
  • 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.
