sulphur trioxide

Colourless solid prepared by reacting sulphur dioxide and oxygen in the presence of a vanadium(V) oxide catalyst in the contact process. It reacts violently with water to give sulphuric acid.

The violence of its reaction with water makes it extremely dangerous. In the contact process, it is dissolved in concentrated sulphuric acid to give oleum (H2S2O7).
