Title: THF - GBL (FeSO4)/H202
Post by: Belial on April 26, 2002, 06:51:00 PM

This was brought up by foxy during an intereting discussion on routes to GBL

"THF (0.5 mol) and 0.1 mol FeSO4 in H2O was treated
dropwise with 1.05 mol 30% H2O2 at (less than)30°C and
the mixt. stirred 3 h at 30°C and 8 h at 45°C to give
61.6% g-butyrolactone."

Would there be room for scaleability here, or would the chance of evil peroxide formation be too great?
Any other perveivable problems with scaling?

Respect
Belial!
