A PHOTO ESSAY ON THE NITROMETHANE AL/HG

Then a wisp here and there of white material started to appear, and within 30 seconds there were giant clouds of puffy MDMA HCl cascading out of solution. But be careful with the addition rate at this point, as a rate that is much faster than this could easily send the reaction into overdrive not good. I do not own a gigantic sep funnel, so I decided to extract the mix directly in the beaker. This worked amazingly well. In other words, you have to watch those two things and sort of adjust the addition so that they proceed at approximately the same rate. When cold, the garbage gets a lot less mobile and it is easy to decant the toluene away from it.

While this was cooling,I dumped the contents of the reaction flask into a mL beaker. The reduction ran hot but was completely under control, easily stirred, fast, and simple to work up. Sludge after NaOH addition and a little stirring A 3″ stirbar was put in the beaker and it was thoroughly stirred. But if that reaction were performed in isopropanol, the aluminum isopropoxide might just transform all those painstakingly prepared ketones into their corresponding alcohols, while producing acetone as a byproduct. The beaker was covered and put in the freezer for half an hour. This is exactly in line with Methyl Man’s instructions.

Into a separatory funnel no smaller than mL capacity, pour your nice gray reaction mixture, being very careful to keep the stirbar from falling into the sep funnel and breaking it that would be ugly. Thus I have tried with this writeup to help the neophyte who has only physical observations and scant written material to guide him although I suspect and hope that it may even help a few more seasoned cooks as well.

There are more on the forum as well. Then after a few minutes you will see them joined by larger bubbles closer to the size of those seen in boiling water. You may think that a 2-liter flask is oversized for this reaction, but that is precisely the point.

For some strange reason, a large number of people on this site seem to want to use aluminum and gallium for reductive amination of ketones. Reshaping the world of scholarly communication by Dr. Toluene after mixing, mostly done separating.

Sludge in the beaker Figure After the 30 minutes, dump the nitrojethane of the beaker into a strainer and rinse thoroughly with distilled water to remove as much of the mercury salts as possible.

Also, acid is usually added to prevent dimerization. During the peak of the reaction, I watched what was going on very closely, but I really didn’t need to do anything at all except make sure that the addition was going at a rate that would make the whole thing take minutes.

Filtration Sodium Hydroxide Chemistry Nature. If you like, do as Mr. This mixed the two phases well. I nearly shit my pants.

Reductive Amination of MDP2P with Al/Hg + Nitromethane

I believe that doing this really helps facilitate thee amalgamation process that is about to occur. Gazeta Do Rzeczy Nr. Then I set up to gas the toluene again. Nitromethane Synthesis I beleive I nitromethahe recently that only 2 chemical plants currently make nitromethane,that’s one of the reasons it’s so expensive. Then the NaOHsolution was poured into the mL beaker with the sludge. Set a drip rate of approximately 1 drop per second at this point and no faster. The mix was starting to get very viscous, so I added another mL of MeOH down the condenser which greatly improved things.

There was probably no more than about 15 mL of toluene left floating on the sludge in the beaker when I was done. The formerly gray sludge turned darker, andthe NaOH started reacting with the remaining aluminum, making a foamy, smelly mess in the beaker.

This Aug static snapshot is hosted by Erowid as of May and is not being updated. As the reaction progresses only a few minutes after the addition was started, you will observe that the aluminum is breaking up fairly rapidly. Some pieces hadstarted to float. My yields were awesome and the purity was excellent.

Reductive Amination of MDP2P with Al/Hg + Nitromethane

A does and finish off with a final small extraction of mL toluene just to get the last of the stuff. Sludge after NaOH addition and a little stirring A 3″ stirbar was put in in beaker and it was thoroughly stirred. This is no problem. This mixed the two phases well. A does it just to be sure. I do not own a gigantic sep funnel, so I decided to extract the mix directly in the beaker. A as he struggled to match up the correct combination of ratios and conditions that would allow a smooth, consistent reaction and predictable results every time.
