Chemical properties of amines:
... The higher the value of Kb is, the greater the dissociation of the base. Amines have Kb values slightly higher than amonia. Thus aliphatic amines are stronger bases than amonia. Like amonia, compounds with amino groups can also neutralize hydronium ions. This neutralization occurs very rapidly and e ...
