DEHA N,N-Diethylhydroxylamine | CAS 3710-84-7

• N,NDiethylhydroxylamine (DEHA) is an organic hydroxylamine compound with molecular formula C4H11NO, appearing as colorless to pale yellow transparent liquid. It is a common water treatment agent and polymerization inhibitor. It belongs to substituted hydroxylamine fine chemicals, with wide usage in power boiler deoxygenation, monomer polymerization inhibition and organic reduction synthesis.
• Its core role in industry: It is widely used as boiler feedwater oxygen scavenger for thermal power plants, polymerization inhibitor for butadiene, styrene and acrylic monomers, reducing agent and intermediate for organic synthesis.

• Excellent oxygen scavenging performance, can react rapidly with dissolved oxygen in boiler water, effectively reduce corrosion of boiler pipeline.
• Good polymerization inhibition effect, can capture free radicals, inhibit premature polymerization of unsaturated monomers during storage and transportation.
• Low volatility under working temperature, good compatibility with water system.
• Mild reducing property, stable under sealed normal temperature storage.
• Low toxic profile compared with traditional hydrazine deoxidizer, friendly for water treatment operation.

DEHA is commonly used in:

• Polymer industry (vaporphase polymerization inhibitor for styrene, butadiene and isoprene; short stopper for SBR/NBR rubber emulsion polymerization).
• Water treatment field (oxygen scavenger for boiler water system, prevents pipeline and equipment corrosion).
• Photographic chemicals (color stabilizer to avoid discoloration of photosensitive materials).
• Fine chemical synthesis (used as reaction intermediate, antioxidant and stabilizer for phenolic compounds).
• Electronic chemicals (auxiliary agent for photoresist residue removal in microelectronics manufacturing).

1. Q: What is DEHA mainly used for in water treatment?

A: DEHA is an oxygen scavenger for boiler feed water. It removes dissolved oxygen to prevent corrosion of boiler, condenser and pipeline in thermal power system.

2. Q: What are the storage requirements for DEHA?

A: Seal and store in cool, dry and ventilated warehouse. Keep away from strong oxidizing agents, heat source and open flame. Shelf life is 12 months under sealed and normal temperature condition.

3. Q: What is the difference between DEHA and hydrazine hydrate for boiler deoxidation?

A: DEHA has lower toxicity, no carcinogenic risk, and can form protective passivation film on metal surface; hydrazine hydrate has high toxicity and strict discharge limits.

4. Q: Can DEHA be used as polymerization inhibitor?

A: Yes. It can be used as free radical scavenger to inhibit polymerization of styrene, butadiene, acrylic monomers during transportation and storage.

5. Q: Is DEHA miscible with water?

A: DEHA is miscible with water and soluble in alcohols and many organic solvents.

6. Q: What's the packaging for DEHA when shipped?

A: Usually 200kg sealed steel drums or 1000L IBC tanks, loaded on pallets for sea shipments.
