They asked you a simple question, they didn't attack you.

I am a bit sceptical of the 150g MeAmineHCl from 80g Hexamine when a regular hex to Mex might yield 40-60% by weight. How is this possible? The calculations are beyond me.
Why not work it up regularly just to be sure. Ie an alcohol recrystallization, then a chloroform wash to remove any excess Hexamine.

Jabber; let me know if I can help in confirming his results. I think a vac reflux setup could be done with a conventional distil kit by assembling a single neck flask, then condenser, then vac adapter at the top with the big hole sealed and vac on the vac port.

Sumerian; Dude please don't leave. Your work is inspirring, someone will try to confirm it soon. It's just that people are naturally sceptical around here with stuff like the PdAcetate fiasco, the MDP-pol fiasco, etc etc. I would eagerly attempt to confirm your results but am labless for the time being. I hope you'll continue to make more groud breaking contributions.

I belive the starting product could be the difference, did ya all use the name brand?

Summerian's write up does not account for possible ammonium chloride contanimantion, which you would expect to be the major side product weighing 50% or more of the total product's weight.

A mixture of ammonium chloride and MeAm.HCl will be very hard to distinguish from a pile of pure MeAm.HCl because ammonium chloride has no significant odor. The mixture will melt in air just as pure MeAm.HCl will so that is not a reliable test either. Also, a chemical test that only tests for an amine will show true for both products.

Finally, ammonium chloride would not interfer with Al/Hg amination procedures. The ammonium chloride, even though it is less reactive, will still form MDA. Most people won't complain about MDMA that has been contaminated with MDA This amination procedure calls for a molar excess of MeAm.HCl so using a contaminated product may even result in no loss of total yield of MDMA.

The possibility that ammonium chloride could have easily passed through Sumerian's purification process does not mean that it did infact pass through. An easy way to detect ammonium chloride would have been to attempt to dissolve the product in dry boiling alcohol.

Dr. Faust informs me that using an aspirator has several benefits. That nasty smell is sucked down the drain and covered up. In fact, placing a bubbler filled with an H2SO4 solution between the receiving flask and the aspirator make the smell almost nonexistant. Also the entire process of removing the water goes much faster, more methylamine is produced, and less ammonium chloride is present in the final mixture.

I have not ran this same scenerio several times, different reflux temps, longer periods, different brands of hex, etc,. and have found very different results,.

I can't put my chemistry challenged finger on it, but almost every time i ran this experiment, the hexamine would dissolve into the HCl, then while being left over night, no reflux- 24 hour wait at 20C, these crystals would appea, depending on reflux temp, the warmer the reflux the yellower/greener the crystals would become,
Although at the time being an idiot, i noticed that the first crystals (pure whitethat form in the wet HCL solution were almost mousse like in texture, or even gelati like,.
I assumed this shit to be the contaminant, which I filtered off, to leave me with this greeny solution, which hence dried to give me what i thought to be methyhlamine,.

gotta go

hellman,

If it's true and and can be tlc, nmr tested, then You have done well!.
