3710-84-7 - Nature
Open Data Verified Data
diethylhydroxylamine is liquid at room temperature. Soluble in water, the aqueous solution is weak alkaline. Above 570 deg C due to oxidation and decomposition, decomposition products of acetaldehyde, dialkylamines, iron acetate and acetaldehyde oxime, and a small amount of ammonia, nitrate and nitrite formation. It is highly volatile when exposed to heat.

3710-84-7 - Use
Open Data Verified Data
used as a steam boiler water system of oxygen scavenger, not only suitable for low temperature oxygen removal, but also suitable for high temperature steam condensate circulation system of oxygen removal. Its oxygen scavenging function is superior to hydrazine and carbohydrazide. When a catalyst is present, its oxygen scavenging function is higher. Diethylhydroxylamine is also used as a passivator for metals on the water side of the device. In addition, diethylhydroxylamine can also be used as a polymerization inhibitor, a chain transfer agent, for the determination of aldehydes, and as an antioxidant and a corrosion inhibitor for metal equipment.
