      THF - GBL (FeSO4)/H202  Bookmark   

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)30C and
the mixt. stirred 3 h at 30C and 8 h at 45C 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?
