Slowly pour the NaOH solution into the sep funnel gloves and glasses! The toluene was chilled and filtered and the filtrate dried, yielding another 4. Also, according to the thread I linked, apparently very pure gallium doesn’t seem to work as well for some reason. The would also work in isopropanol I think , but then you have to worry about potential reactions from aluminum isopropoxide, if there are any ketone or aldehyde groups present. Absolutely nothing had happened after several minutes and I was convinced I had totally fucked up.
Closeup of foil balls Figure 4: They are as follows:. I’m telling you, LOTS of trial and error came before this writeup. It seems that this deviant individual engaged in some organic chemistry earlier this month, and had taken notes and pictures. While this was cooling, I dumped the contents of the reaction flask into a mL beaker.
In less than 10 minutes, faint bubbling was visible, the solution was gray, and the aluminum was distinctly less shiny. I believe that doing this really helps facilitate the amalgamation process that is about to occur.

I started cutting Reynolds Heavy Duty aluminum foil into about 1″ squares, to make a total of Nitromethane was by adding materials such as mono methylamine nitrate. This was left to stir slowly for about an hour, at which time almost allthe bubbling was done and the foaming had xl/hg. Give it a few more 5-second stirs over the next few minutes. Then after a few minutes you will see them joined by larger bubbles closer to the size of those seen in boiling water.
I arranged to have an ordinarycondenser in the center hole. It was then filtered into a new beaker also super dryand the MgSO4 in the filter washed with a little new toluene.

Nitromethane Synthesis I beleive I read recently that only 2 chemical plants currently make nitromethane,that’s one of the reasons it’s so expensive.
While this was cooling, I dumped the contents of the reaction flask into a mL beaker. My yields were awesome and the purity was excellent. Place about 3 lbs ice into your bucket. Bubbling as NaOH reacts with remaining aluminum Figure A uses Heet that is fulfilling this function, and maybe it’s even in all MeOH except expensive absolute anhydrous stuff.

Materials and Apparatus It seems that this deviant individual engaged in some organic chemistry earlier this month, andhad taken notes and pictures. You may think that a 2-liter flask is oversized for this reaction, but that is precisely the point. He donned his Red Baron attire and jumped into his plane. Then add 55 gm of aluminum squares appx 1″ sq that have been cut from pie tins. Sludge after NaOH addition and a little stirring A 3″ stirbar was put in the beaker and it was thoroughly stirred.

This is due in large measure to the sensitivity of this reaction to even the most minor changes in its many variables. The metal transfers electrons to the substrate, but a proton source is still needed for the full reduction to amine. I’m telling you, LOTS of trial and error came before this writeup. Everything else took care of itself. The subject found for his own personal reasons that this smaller scale was much easier to manage not the least of which is that even with a huge 4-liter separatory funnel, at this smaller scale it gets pretty filled up!
After this time two layers were observed. There was a total of 8.
