Diethylhydroxylamine (DEHA) - 85%
Chemical synonyms: N-Ethyl-N-Hydroxy-Ethanamine; Diethylhydroxylamine 85%
Product description
DEHA 85% solutions is available as a yellow liquid with an amine-like odor.
DEHA products are manufactured by the reaction of a triethylamine and a peroxide, followed by purification and distillation. Eastman manufactures DEHA Anhydrous and DEHA 85%.

Both DEHA Anhydrous and DEHA 85% function primary as radical and oxygen scavengers.

DEHA is used in boiler water treatment applications, as an oxygen scavenger for medium and high pressure boilers. DEHA 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, DEHA is also used in refinery chemicals and other niche markets, such as:

Microelectronics industry: for example, DEHA is formulated to remove residual photoresist and other residue from microelectronic parts.
Photographic industry: DEHA is blended with other chemicals to produce good color development.
The reduction of toxic heavy metals such as hexavalent chromium to their more environmentally-friendly counterparts such as trivalent chromium is done using an aqueous solution containing DEHA.

DEHA (N,N-diethylhydroxylamine), 85%
Consumer & Industrial Applications
Photoprocessing Chemicals: Used in photographic developer formulations, N, N-Diethyhydroxyamine (DEHA) is critical for quality color development in the photographic industry. It can also be used to remove residual photoresist residue from microelectronic components. 

Fuels Applications
We manufacture a range of certified diesels and gasolines to support worldwide standards for the engine industry, oil additive suppliers, and auto manufacturers. Certified fuels are formulated to specific properties to provide the necessary consistency for various engine test protocols and development. Utilizing certified fuels reduces fuel variances that could affect the quality of various engine analyses.

Polymers and Rubber Applications
Polymer Modifier: We produce heavy mercaptans, such as DEHA 85%, which function as chain transfer agents in processes where control of molecular weight is critical. 

Rubber Modifier: In addition to polymer modifiers, DEHA 85% can be used to convert rubber to more durable chemicals through vulcanization. 

Water Treatment Applications
Di-ethyl hydroxylamine (85% & 98%) are used in water treatment formulations to control corrosion in boilers. DEHA has the property of oxygen scavenging, prevention of corrosion of steel and other metals. It is effective in removing dissolved oxygen thus slowing or eliminating corrosion. It can produce a protective oxide film on ferrous-based metals, thus offers enhanced corrosion protection. In boiler water systems (the vapor and liquid phase system). DEHA is considered a hydrazine replacement and is less toxic.

DEHA 85 N, N-Diethylhydroxylamine 85, (water content 15% max.)
Short stopper of polymerization in production of SBR/NBR and poly butadiene polymer. Polymers short stopped by DEHA are stable, and do not change their viscosity due to incomplete reaction and maintain their color.
Handling precautions:
DEHA is a harmful and flammable liquid
DEHA can react violently with strong oxidants
For further detailed information, please refer to Material Safety Data Sheet
Aplications:
Short stopper of polymerization in production of SBR/NBR and poly butadiene polymer. Polymers short stopped by DEHA are stable, and do not change their viscosity due to incomplete reaction and maintain their color.
Polymerization inhibitor used as anti-popcorn agent in styrene/butadiene monomer production. Due to the inhibition of the formation of high cross-linked polymer, damage of equipment and pipes can be avoided.
Water treatment chemical to avoid corrosion in water boilers by binding oxygen (Oxygen scavenger). This maximizes the energy use and life of the boiler system.
Film development industry,where it is used as anti-oxidant in formulations for rapid development of color prints. It also acts as an initiator in the development process.
DEHA acts as an inhibitor because it scavenges peroxides, oxygen and organic radicals. It is used as a colour stabilizer in polymers and fuel systems.

Industry Uses
Corrosion inhibitors and anti-scaling agents
Process regulators

Consumer Uses
Water Treatment Products

Application Areas:
 
Water Treatment
DEHA is used in Water Treatment Chemical Formulations for controlling corrosion in boiler very effectively due to its property of oxygen scavenging.It scoresover conventional hydrazine hydrate since it is far less toxic and meets the standard for disposal of blow offs without any difficulty giving a good protection against corrosion at the same time.
 
Polymerization
DEHA's powerful free radical scavenging ability coupled with its moderate volatility and relatively low order of acute toxicity makes it an ideal "popcorn Polymer "/ vapour phase inhibitor for olefins or styrene monomer storage & recovery system.Because of its capability of inhibiting polymerization in the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, isoprene and other monomers containing a reactive double bond.

Photographic Chemicals
DEHA has reducing property, so it is used as an auxiliary chemical photographic developer for instant colour photos. Also, DEHA is effective in stabilization of image and in the prevention of discolouration.

Decolourisation
Phenol and Phenolic antioxidants can be decolourised with DEHA.
 
Inhibitors
DEHA can be used as a colour stabiliser of monoalkyl phenol.

Silicon Rubber
DEHA can be used as a raw material for the hardener of the Silicon Sealant and coating agent.

Storage
Can be stored and handled in equipment made of stainless steel of Type SS304 or SS316 or steel lined with glass, polypropylene or polyethylene. Storage in mild steel equipment or containers is not recommended. DEHA drums should be stored in a cool and well ventillated area, away from sources of ignition.
Forms two layers for concerntration from 33 to 87 wt %.
 
Packing
180 kg net wt. in new UN approved HMHDPE drums / In ISO Tanks of 20 Mt's capacity.

Health & Safety
DEHA is irritating to skin,eyes and the mucous membrane. In case of contact,affected area to be washed with plenty of water for atleast 15 minutes.
 
In case of inhalation,victim should be moved to fresh air and oxygen should be administered.

In case of ingestion,victim should be made to consume copious quantity of milk and water. Medical advice should be sought at once.
