Solubility of SO2 in concentrated H2SO4

Solubility of SO2 in concentrated H2SO4

Solubility of SO2 in concentrated H2SO4

(OP)
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

PS. If not solubility, it may be partial pressure of SO2 over SO2 solutions in H2SO4 - I'm not sure which name is more accurate.
PS2. I'm sorry for double-posting (in another part of this forum) but it's very important and I hope that more people will see my post in this section.

RE: Solubility of SO2 in concentrated H2SO4

If you can't find anything free, the following shows data you can buy from the Detherm databank at
http://i-systems.dechema.de/detherm/mixture.php?action=New&;?

best wishes,

The first number is the number of lines of data, the second number is the price (i.e. 80.00=$80):
