After reading Foxy2's reference of JP 53087347 & 19780801, I went ahead and got my dare-devil twin double who fills in for me when I feel a bit worried about performing a reaction to experiment with this reference. I decide for the safety of every one in the immediate area that 1/5 scale would be a moderate test batch. As you can see, my dare devil is to me, what Zwitterion was to Eleusis.History should have taught me better. Anyways, on to the chemical story, the dare devil cautiously added 8.1ml (7.2g, 100 mmol) of clear colorless THF (distilled from pipe cement and stored over aqueous brine/bisulfite) and 3.0g (20 mmol) of pale green FeSO4.H2O. Putting this into a water bath at room temperature, he slowly started to drip in 20.4g of 35% H2O2 (7.2g H2O2, 210 mmol). After a few drips were added, the solution went to a dark burgandy red. Say, isn't that the color FeSO4 is supposed to go if there's peroxides forming in the mixture? Oh well! Then it started to boil vigorously. Oh shit! So, the brilliant dare-devil, takes this reaction to an ice-water bath and proceeds to very slowly add all 20.4g of 35% H2O2. But nothing has happened, no real increase in temperature... what's going on? So, he removes the ice-bath.. and warms it to around 15C. Nothing. Around 20C. Ahh.. it's getting warm, maybe we should put it back in a cold-water bath. So that's done. But that doesn't slow down the reaction, soon, this 30ml mixture is filling the 100ml flask it's in, and climbing a 250mm reflux condenser to shot out the top and spray the ceiling. Hmm... The dare devil stops. The dare devil thinks. The dare devil vacates the room. Everything looks OK. He floods the flask with cold water and cleans up the area... then washes everything and thinks... maybe we should try this again, just maybe, keep the mixture at 20C (NO LOWER!), halve the scale and slow the drip rate down to less than 1 drop / sec...
