N,N- Diethyl hydroxylamine (DEHA)
Molecular Formula: (C2H5)2NOH,
Molecular Weight: 89.14
Physical and Chemical Properties: colorless or primrose transparent
liquid whose color will gradually becomes yellow if kept for quite a
long time. If shone by the sunlight directly and open to the air, it
will change its color more rapidly. Shaken violently, it will become
turbid for a while and several hours later it will become clear again.
It has the smell of amine, soluble in organo solvents including ethanol,
ether, chloroform, benzene, etc..
It is stable when PH is during 7-11. It can actively react with organo
hyperoxide and free base. It can react with ozone and nitrogen dioxide.
Non-toxic, easily be removed from monomer. Its solubility in the water
is about 35%, at normal temperature its saturated solution is <15%.
B.P.: 125-133, Density: 0.896-0.902 (20),
refractive index 1.4173 (25), flash point: 46.1-48.4.
