I don't have a water phase diagram in my head, somebody said phase
boundary between liquid/vapour vanishes at about 350 (?) deg C.

If it has some oxygen dissolved in it, I think. I doubt equilibrium will
imply noticeable amounts of free oxygen at these still relatively mild

Sounds interesting, I did not knew. Does it hydrolyse the dioxines as well?
(The best stuff I knew of, apart from CrO_3 in sulfuric acid, was Carot's
acid, a hot mix of strong hydrogen peroxide (perhydrole, H_2O_2) and
conc. sulfuric acid, I remember it dissolved a dead fly tracelessly within
