pH: Approximately neutral (pH 6-8)

Application:

1. Oxygen Scavenger: DEHA is primarily used as an oxygen scavenger or reducing agent in boiler water treatment. It reacts with dissolved oxygen in water, preventing corrosion and pitting in boiler systems. DEHA helps maintain the integrity of boiler components by reducing the oxygen concentration, thereby minimizing the risk of oxygen-induced corrosion.

2. Polymerization Inhibitor: DEHA is employed as a polymerization inhibitor in various industries, particularly in the production and storage of monomers and polymer resins. It prevents the unintended polymerization of unsaturated monomers, such as acrylics, styrenics, and vinyl compounds. DEHA acts by inhibiting free radical initiation and termination reactions, extending the shelf life and stability of these materials.

3. Photographic Chemical: DEHA has applications in the photographic industry as a developing agent and stabilizer. It is used in black and white photographic developers to reduce silver halides and produce the desired image. DEHA also acts as a stabilizer, preventing the degradation of photographic emulsions caused by oxidation.

4. Chemical Intermediate: DEHA serves as a precursor or intermediate in the synthesis of various organic compounds. It can undergo reactions such as oxidation, reduction, and condensation to produce different chemicals used in industries like Chemical, agrochemicals, and dyes.

5. Antioxidant: DEHA exhibits antioxidant properties and is utilized as an antioxidant additive in various products. It helps protect against the oxidative degradation of polymers, fuels, and lubricants during storage and use. DEHA scavenges free radicals and prevents the chain reaction of oxidation, extending the lifespan and performance of these materials.
