Birch?
Any asshole can cut and paste.
Lithium is the stumbling block in this rection not ammonia! If you lived on a farm you'd have just as much anhydrous ammonia as you have bullshit! This is also considered the "Nazi Method" it's far from being a secret.
The Birch Reaction:
From Ely & McGarth J Forensic Sci 35:720-3, 1990 verbatim
Procedure
All chemicals were reagent grade, with no special treatment of the tetrahydrofuran (THF), and the atmosphere above the condensed ammonia was not flushed with nitrogen gas. A three-neck flask was cooled in a dry ice/acetone bath. A condenser was fitted in the center neck, an additional funnel containing l-ephedrine base in THF was fitted into one side neck, and a rubber stopper fitted with a glass tube extending to the bottom of the flask was fitted in the third neck. Anhydrous ammonia gas was condensed and collected in the flask. Small pieces of lithium metal were rinsed in petroleum ether, patted dry, and added to the condensed ammonia. A deep royal blue color was noted as the lithium metal dissolved in the condensed ammonia. The l-ephedrine was added dropwise to the lithium ammonia solution over a period of approximately 10 min. with stirring. When all of the l-ephedrine had been added, ammonium chloride was added slowly to the solution. The flask was removed from the cooling bath, and the cooled ammonia was allowed to warm to room temperature and evaporate from the flask through the side necks. When most of the ammonia had evaporated, water was added to the remaining solution until it cleared and any remaining lithium metal was decomposed. The remaining solution was removed from the flask to a separatory funnel, where the aqueous layer was discarded. The THF layer was dried with magnesium sulfate, and the hydrochloride salt of the methamphetamine was made by bubbling hydrogen chloride through the THF.
The time required for the reaction to proceed from the condensing of the ammonia gas in the reaction flask until the excess lithium was decomposed was approximately 1 h. The majority of the time was spent waiting for the condensed ammonia to evaporate from the reaction flask. The reaction was found to reduce l-ephedrine to d-methamphetamine quickly and easily. Furthermore, it was found that the reaction converted phenylpropanolamine to amphetamine and methylephedrine to dimethylamphetamine. It was also found [in a second synthesis] that the ephedrine would reduce to methamphetamine without the addition of ammonium chloride as a quenching agent.

Re: Birch?
Annhydrous Ammonia will seek out and bond with any nearby water. This means your eyes and airway. You should always have a few gallons of water handy to dowse yourself with, as it may save your life. One breath of concentrated ammonia vapor is enough to burn your trachea and make it impossible to breathe.
High concentrations of ammonia (above 15%) are explosive. Keep this in mind when its time for your mid reaction toke.
gas law says that 1 mole of any gas will occupy 22.4 liters of volume at standard temp and pressure. a mole of ammonia is 17 grams. In short, it takes very little ammonia to fill up a room.

Re: Birch?
Holy..... FUcking CHrist!!!!!!
This is Fuckingfascinating.
Misterclean, why that was the smartest shit I've heard from you on this board so far!!!
Why is it that normally you misspell words, make poorly thought out comments, and your just generally stupid,
But all of a sudden you say something SMART... and WITTY..
Why it's almost like those words DIDN'T COME FROM YOU AT ALL!!!!
M C.. you are REALLY SOMETHING ELSE.
Slim.

Re: Birch?
hmmm, i have been following this this little scene about Mister Clean and Slim for a few days now, and I was just wondering what the hell is going on? Slim has made ALOT of claims against Clean, but I haven't seen a single responce on these charges from Clean. Not that I am picking sides or anything, just wondering whats the score with all this?

Re: Birch?
Before rxn toke, or after I can see. But during? I guess you will be taking that mid plastic surgery toke when your rxn EXPLODES IN YOUR FACE.
I am not trying to take sides either, but maybe Mister Clean (and no offense) doesn't reply because the acusations are true?

Re: Birch?
Actually, the "mid reaction toke" comment is part of my original post. This faker simply appropriated it.
It is unlikely that you will be toking away while the NH3 concentration in the air reaches anywhere near 15%. You would run gagging and tearing from the room long before that could occur.
This post was originally in regards to generating ammonia from fertilizer, a 3 to 5 hour process.
You really think I'm gonna go that long without lighting a few up?
