please tell me how to prepare SO3 cristals? Can I use H2SO4 and freeze it, or need use SO2 + O2?

Do you know how nasty SO3 is?

SO3 crystals are not exactly that they are the trimmer of Sulfur trioxide and form a solid below 16 degrees C. It is so hygroscopic that there is very little chance of producing it pure with out destroying your equipment and/ or your self.

 

You must know that this substance will ignite on contact with organic materials and there has been reports of the ignition being delayed by days at a time before the floor of a lab burst into flames from the heat of hydration.

 

If you don't mind me asking what in the world would one want with solid SO3?
