A PHOTO ESSAY ON THE NITROMETHANE AL/HG

Report on the Second Sakyadhita Conference: This is where you can take advantage of Mr. At this point the mix had a very distinct steel blue-gray color, like Methyl Man describes. In less than 10 minutes, faint bubbling was visible, the solution was gray, and the aluminum was distinctly less shiny. Then I set up to gas the toluene again. I would expect there to be some remainingMDPP with its slight color, or for some reaction impurities to give a color too.

In actuality, the foil does not get “ground,” but rather, each individual piece just gets compacted and compressed. I would expect there to be some remainingMDPP with its slight color, or for some reaction impurities to give a color too. But this was slightly milkywhite. When I got back things had cooled considerably and the mix was mostly an amorphous gray with just the tiniest flecks of white mixed in. The crystals are settling, and have formed a thick layer at the bottom of the beaker. I’ve done a similar reaction plenty of times, although I always used galinstan, an alloy of gallium, indium, and tin, with a melting point below room temperature.

I started cutting Reynolds Heavy Duty aluminum foil into about 1 squares, to make a total of Then I set up to gas the toluene again. I ;hoto the whole reaction, with crystallization, in the span of an evening.

Most of the toluene was poured off the top.

Reductive Amination of MDP2P with Al/Hg + Nitromethane

This is where you can take advantage of Mr. My wl/hg wereawesome and the purity was excellent. A was never successful in using thicker aluminum, and doesn’t want to be! I was worried, because the toluene had virtually no color to it.

Toluene is kina hard for me to get, so next time I plan to try xylene instead.

It is around this same time that the appearance of the aluminum will change from its normal shiny silver color and start to take on a dull gray look, accompanied by a gray cloudy look that begins forming in the MeOH. My yields were awesome and the purity was excellent. Give it a few more 5-second stirs over the next few minutes.

When I got back things had cooled considerably and the mix was mostly an amorphous gray with just thetiniest flecks of white mixed in. I would expect there to be some remainingMDPP with its slight color, or for some reaction impurities to give a color too.

In less than 10 minutes, easay bubbling was visible, the solution was gray, and the aluminum was distinctly less shiny. I believe sl/hg doing this really helps facilitate the amalgamation process that is about to occur. Another mL of toluene was dumped in the beaker and thoroughly mixed.

Then add 55 gm of aluminum squares appx 1″ sq that have been cut from pie tins. The metal transfers electrons to the substrate, but a proton source is still needed for the full reduction to amine. The foil doesn’t really get “ground”, but as Methyl Man says, it gets all balled up into little globs.

A does it just to be sure. But he doesn’t add it anymore and it definitely doesn’t hurt anything. During the peak of the reaction, I watched what was going on veryclosely, but I really didn’t need to do anything at all except make sure that the addition was going at a ratethat would make the whole thing take minutes.

Your reflux should be unnervingly vigorous as the amalgamation really thf to pick up speed, with the MeOH literally pouring down out of the condenser. The would also work in isopropanol I thinkbut then you have to worry about potential reactions from aluminum isopropoxide, if there are any ketone or aldehyde groups present.

I observed firsthand the trials and tribulations of Mr. A Buchner funnel tightly packed with crystals Figure Chill, filter and dry. Within 7 minutes, the reaction was beginning to boil vigorously. We are always happy to assist you. Sludge In BeakerFigure About to drain off the very last bit of sludge-water. We are nonprofit website to share and download documents.

If your reaction vessel is above gallium’s melting point, you should see your gallium precipitate as little metal droplets at the bottom. Amalgamation complete Ice water was started flowing through the condenser.

Apparatus When the MeOH was ready all HgCl2 dissolved nitrromethane, it was also dumped in the flask and the condenser was put in place.

The toluene was drained into a washed, acetone-rinsed, thoroughly dried beaker with about 35g anhydrous MgSO4.
