N,N-Diethylhydroxylamine Usage And Synthesis

Description

N,N-Diethylhydroxylamine is a colorless and transparent liquid with a boiling point of 125-130 °C and an ammonia odor. It is easily soluble in water, soluble in ethanol, ether, chloroform and benzene.

Chemical Properties

liquid

Uses

N,N-Diethylhydroxylamine has the following various uses:
1.As a vinyl monomer, used in efficient inhibitor agent of conjugate olefins.
2.In liquid or gas phase, if end gather seed is existed,it can be used as inhibitors of end gather.
3.It's a excellent end agent in process of Emulsion-polymerized styrene butadiene rubber.
4.It's a antioxidants of the unsaturated oil and resin.
5.In the environmental protection,it’s good photochemical smoke inhibitors.
6.It's used as corrosion inhibitors in the equipment of the boiler feed water and steam heat exchange.
7.It's used as antioxidant in photography screens potions. 

Uses

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

Uses

Diethylhydroxylamine has been suggested as a stabilizer for color forma­tion for monoalkylphenols and phenolic antioxidants. It has also been reported to stabilize emulsions used in the latex industry and for Spandex rubber, as well as a reducing agent for quinones and a monomer stabilizer or inhibitor.

General Description

The product is 85wt.% solution of N,N-diethylhydroxylamine. The reaction of N,N-diethylhydroxylamine with tert-butylhydroperoxide has been studied. It participates in the preparation of symmetrical and an isomeric mixture of unsymmetrical phthalocyanines. It undergoes degradation on exposure to radiation and affords light hydrocarbons. Qualitative and quantitative analyses of the produced hydrocarbons have been reported. It also participates in the conversion of quinones and quinonemonosulfonimide to the corresponding hydroquinones and sulfonylaminophenols, respectively.

Health effects

The effects of diethylhydroxylamine (DEHA), a potent free-radical scavenger, on lipid peroxidation of rat liver microsomes were investigated in vitro. DEHA strongly inhibited ascorbate-dependent nonenzymatic microsomal lipid peroxidation. It also completely inhibited nonenzymatic lipid peroxidation of heat-denatured microsomes, indicating that inhibition is protein-independent. DEHA only moderately inhibited NADPH-dependent enzymatic microsomal lipid peroxidation. 

Safety Profile

Poison by skin contact. Moderately toxic by ingestion and intraperitoneal routes. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.
