Strictly, Diethylhydroxylamine is N,N-diethylhydroxylamine.
Diethylhydroxylamine is mainly used as an oxygen scavenger in water treatment.

Diethylhydroxylamine is a volatile oxygen scavenger and reacts in a ratio of 2.8/1 DEHA/O2.
Diethylhydroxylamine 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, Diethylhydroxylamine acts as an oxygen scavenger throughout the entire boiler system due to steam carryover.
Diethylhydroxylamine also reacts with ferrous metals to form a passivized film of magnetite throughout the boiler system.

Diethylhydroxylamine has these other uses:

-Polymerisation inhibitor
-Color stabilizer (photographics)
-Corrosion inhibitor
-Discoloration inhibitor (phenolics)
-Antiozonant
-Radical scavenger

Use and Manufacturing of Diethylhydroxylamine

Diethylhydroxylamine is a N,N-dialkylhydroxylamine.
Its interaction with the surface of clean silicon(100)-2x1 has been studied by various theoretical and spectroscopic methods.
H2O2 along with superoxide and diethylnitroxide radicals have been reported to be formed during the photochemical oxidation of Diethylhydroxylamine.

Application of Diethylhydroxylamine
Diethylhydroxylamine may be employed as a ligand in the preparation of unsymmetric mixed ligand oxadiazoline and/or imine platinum complexes.
Diethylhydroxylamine may be used in the synthesis of organometallic clusters of mixed hydrazide/hydroxylamide clusters of zinc.

Applications of Diethylhydroxylamine
-Electronic chemicals
-Photographic chemicals

-Upstream O&G-production
-Water treatment industrial

Diethylhydroxylamine is available as a yellow liquid with an amine-like odor.
Diethylhydroxylamine products are manufactured by the reaction of a triethylamine and a peroxide, followed by purification and distillation.
Eastman manufactures Diethylhydroxylamine Anhydrous and Diethylhydroxylamine 85%.

Both Diethylhydroxylamine Anhydrous and Diethylhydroxylamine 85% function primary as radical and oxygen scavengers.
Diethylhydroxylamine is used in boiler water treatment applications, as an oxygen scavenger for medium and high pressure boilers.
Diethylhydroxylamine also functions as a free radical scavenger in polymerization, it is a short stopper in the production of styrene butadiene rubber.

Beyond its application as scavenger, Diethylhydroxylamine is also used in refinery chemicals and other niche markets, such as:

Microelectronics industry: for example, Diethylhydroxylamine is formulated to remove residual photoresist and other residue from microelectronic parts.
Photographic industry: Diethylhydroxylamine is blended with other chemicals to produce good color development.

Diethylhydroxylamine is a colorless to pale yellow transparent liquid, available as a 85% and a 98% solution in water.
Diethylhydroxylamine is used in boiler water treatment applications, as an oxygen scavenger for medium and high pressure boilers.

Application of Diethylhydroxylamine
Diethylhydroxylamine has the property of oxygen scavenging and used in water treatment chemical formulation to prevent corrosion.
Diethylhydroxylamine is used as an auxiliary in photographic industry to prevent discoloration.
Diethylhydroxylamine is a vapor phase polymerization inhibitor against double bond monomers such as olefin, styrene, butadiene, isoprene and divinylbenzene.
Diethylhydroxylamine is used as a stabilizer for phenolics.
Diethylhydroxylamine is used as an intermediate for and water treatment chemicals.
Diethylhydroxylamine is also used as a raw material of silicon sealant and coating materials.

Diethylhydroxylamine is an organic compound [(C2H5)2NOH] is a colorless liquid mainly used as an oxygen scavenger in water treatment.
Diethylhydroxylamine is very important to remove oxygen from the boiler feed water as oxygen can cause serious issues in the steam producing plant by fostering corrosion in the total boiler system.
The reasons due to which Diethylhydroxylamine find its popularity as an oxygen scavenger is because of its ability to passivate steel and its low toxicity.
As an Oxygen Scavenger, Diethylhydroxylamine works efficiently removing oxygen at a rapid rate under normal boiler conditions.
Its volatility is similar to amine and has the ability to provide protection to overall condensate system as well as boiler system.

Key Features and Benefits of Diethylhydroxylamine
Completely organic nature
Volatile product, does not add to TDS of blowdown water
Metal passivator and rust converter
Eﬀective condensate line treatment and pH booster
Non-toxic and safer than hydrazine and carbohydrazide based chemicals
Compatible with other boiler treatment chemicals
Compatible with other boiler treatment chemicals
Returns to the feed line with the condensate return so passivates total system
High rate of reaction with oxygen compared with other oxygen scavengers
Offers vapour liquid distribuon ratio of 1.3 and thus distributes all along the condensate circuit
