Solubility of SO2 in concentrated H2SO4

[keekooceeaou]

Hi,

I need data (x-y graph) for solubility of SO2 in concentrated sulphuric acid (approx. 98%) at temperature approx. 80 deg. C.
Can anyone send me this data or give a link/reference?

Thanks in advance for any help,
Paul

I'm sure that this is too late, but check Seidell's Inorganic solubilities book on books.google.com. The book is even in the public domain and can be downloaded.

To my knowledge SO2 is pretty insoluble in really conc. sulphuric acid. I don't know if youre trying to increase concentration above 98% - if thats the case you would usually oxidise the SO2 to SO3 over a catalyst. This is then absorbed by 98% acid in a suitable tower to produce oleum which then forms H2SO4 when water is added.
