Odor:Mild amine odor
PH:pH = 7.7-8
Henrys Law Constant:3.20e-09 atm-m3/mole
Experimental Properties:Dipole moment at 25 °C: 4.09 debye; Dielectric constant at 25 °C: 32.3|Hydroxy radical rate constant = 7.4X10-11 cu cm/molecule-sec at 25 °C
Air and Water Reactions:Soluble in water.
Reactive Group:Amides and Imides
Reactivity Profile:This amine is a very mild chemical base. It does tend to neutralize acids to form salts plus water. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
