Stability: Extremely unstable, easily volatile to form sulfuric acid and sulfur trioxide.

Prohibited substances: alkalis, flammable or combustible substances, active metal powders, water, strong reducing agents.

Conditions to avoid contact: reducing agents, metals

Volatilization principle: not only because of the high concentration, but also because the oleum contains a large amount of electrophilic reagent sulfur trioxide
