What's up?! A bear in my dreams said, "I reacted a methoxyphenyl Grignard with another interesting chemical and the reaction was hot enough to burn me when I placed my hand on the side of the jar. Good sign! The huge pickle jar was allowed to sit for about 20 hours, then it was time for quenching. I added a bunch of ammonia, water and a little ammonium chloride to it. It immediately got hot, then I had to bring it down to my basement, because it started to boil! I used excess Mg in my Grignard, so is that the reason for it being at a pissed off, violent boil? Can all this heat ruin my legal analogue? The bastard's been boiling for about 20 minutes now! I put a ceramic pot under it that's designed for ovens just in case the jar breaks. It just makes me nervous when I can't control a reaction. I thought about dumping all of it into a 10 gallon bucket and overwhelming it with water, but I'm worried that the solvents in the reaction mixture will dissolve the plastic. Help!

Have you tried putting it inside dry ice/acetone bath?
That will suck a LOT of energy out of that reaction, especially if its a small container. It should stop the boiling, and may even make the reaction stop altogether!
Hell, just try a normal ice bath first and see what happens!

No dry ice, but I do have some acetone..I would put it in an ice bath, but if the jar broke, it would spill everwhere.. I have to find a large pail. Peace!

I put on my oven mitts and put the jar into a mop bucket, then I added very cold water. I was gonna go up to the 7-11 and buy a bag of ice, but the cold water is working well by itself. I'm surprised the jar didn't crack. I'm using a ceramic plate as a cover for the jar. I opened it for a second, and all I could see was boiling grey matter. A little chem/water vapor hit me in the face when I opened it, and now I'm feeling a little altered!
When the chems are finished reacting, I need to separate the non-polar toluene, product, ether from the water and slop. Usually, I sprinkle sodium chloride into it until two distinct layers form, but I have a problem, because the salt I have is fucking iodized. How can I remove this shit from the salt? I'll just use TFSE to find other ways to bust up emulsions.
Peace and happy cooking! 8)

Go buy non-iodized salt from the grocery store, and while you're there, pick up a ten lb bag of ice.
Both kinds of salt cost the same $2.25, and they are in the exact sae spot in the store. Some people cannot eat iodized salt, so straight NaCl is so common.

Arrrgh!
Iodized salt contains about 0.003% KIO3! What the fuck is the problem?!? Just use it dammit!
"0.003%"
That's all? Thanks! 8)

When I was doing Grignard reactions in school (college) we were told to use a bucket of ice water to cool the reaction flask if needed. I found I needed ice with some Grignards at home, too. Ice always worked with the reactions I did (phenyl magnesium bromide and benzyl magnesium chloride).

My product was ruined, but at least I've mastered the initiation of Grignards.
