I used different words in yet another Google search of this topic, and finally turned up something relevant.
This is from a PhD thesis at Caltech on functionalized polymers that contained furan rings with -CH2OH groups.
A polymer with furan rings, each bearing 2 vicinal -CH2OH groups was converted into the di-O-mesylate.
A portion of the polymer was heated in a thermogravimetric analyzer and I'll cut/paste from the thesis here:-
"The solid polymer has been subjected to thermal gravimetric
analysis.... The loss of methanesulfonic acid is proposed as the cause of mass loss.
This polymer loses mass in an extraodinarily clean fashion, and at a very low temperature.
Onset of mass loss is at 220 °C, a temperature easily reached in solution. The
onset of mass loss is visually observable: a cloud of smoke rises from the
sample at the same time the spike is recorded. The apparent rise in mass is
associated with the dramatic way the gases leave the polymer sample--the
TGA balance pan is pushed down by the force of exiting masses, giving the
appearance of mass gain." E. Burns, PhD Thesis, Caltech, 1993
Both O-mesyl groups are eliminated to leave the furan ring bearing now two vicinal, methylene (=CH2) groups.
My molecule, C8H14O6S2 = 270 M Wt and I distilled 6.0 g, which is 0.0222 moles.
This should release 2 x 0.0222 = 0.0444 moles of CH3SO2OH, which occupies 0.995 L at NTP. (293 C/ 760 mm Hg)
This corresponds to 0.995 x 393/293 x 760/7 = 145 L at 120 C & 7 mm Hg.
No wonder that the distillation apparatus was destroyed!!!
