After about 5 minutes, the foil lost its shine, became dull, and a small layer of gray sludge (aluminum hydroxide) collected at the bottom of the flask. After 10-15 minutes, the reaction stops, this can be seen by the cessation of gas evolution.
G.PattonThe following observation: 15 minutes after adding water to the aluminum foil and the mercury salt, I have a dark gray water solution with many small bubbles that form a foam. After I pour off the water, I hear the aluminum crackling and white smoke rising, a lot of white smoke.

Was I too early to drain the water, or too late?

ACABobserve that the flow of the bubbles is constant without stops, and observe that the aluminum foil is already well covered with dark gray traces and then you know that your amalgam is ready for further use... keep safe from mercury vapors, always use protection and then everything will be joys.!!.

put it at refluxoin
IM BATMANWhat is it? Reflux condenser???
what you guys thinks about it?
It is need to use in amph synthesis (look at manual topic!)
the rinses when water is used could affect the final yield?
No, you should clean up your amalgam from acid (HNO3 is produced after Al+Hg(NO3)2 reaction).
Diogenes said, just discard the most water possible in 10 seconds and add the solvents and goods...then later in alkali acid purifications should go out the mercury..... im right?
Hg salt isn't dissolve in these solvents.

G.PattonHi Patton, I meant the Hg salt will remain in the discarded water phase, it`s solubility is very low in IPA. Rinsing is always recommended of course.

Hg salts immiscible with IPA. You can avoid rinsing. I got information that it has no influence on Hg in final product at all. One colleague made metal analysis for amphetamine and said that Hg there was 0.0003-0.0004 mg/kg.

G.PattonThank you Patton, you have finally confirmed my theroetical speculations here: http://bbzzzsvqcrqtki6umym6itiixfhn...hesis-from-p2np-via-al-hg-video.196/post-5921

This is real science and is extremely reassuring. My currilent post was only to add my experimeting that using a thicker foil, wasing only once and rinsing as quick as possible, it can still work perfectlty.

important question:

the hydrogen released in the amalgam, its only just hydrogen? or it carries as well aluminum? i assume its hydrogen and IPA, but im in doubt about if the aluminun are released as well....

and if yes, in what quantity, and how dangerous is?
tnx in advance

Hg in Hg2Cl2 has oxidation state +1, you need +2 in HgCl2 or Hg(NO3)2
G.PattonHi Patton, is there any advatage of using HgCl2 instead of HgNO3? The former is more water soluble, and can be made from the nitrate salt quite easily. That said, I don`t like to mess around with such toxic substances if there is no clear advantage.

diogenesHi Diogenes. As I said before, HgNO3 isn't appropriate for amalgam production, only Hg(NO3)2 salt. There are no differences btw Hg(NO3)2 and HgCl2.

G.PattonHi Patton, sorry I meant Mercury Nitrate Hg(NO3)2, but my question was answered. I haven`t tried HgCl2 and I thought there could be a reason why people use it despite the extra step needed to make it from the nitrate salt. Anyway, thank you for your answer.

Hi. Mercury sulphate is exceedingly poisonous. And no, you have to recount the Hg amount in molar ratio.

Hi Guys, Just sharing a recent findings. I have returned to the `good old Al/Hg amalgam reaction, simply for not having enough NaBH4, and not wanted to spend money on it. I used to use Al/Hg, but was never successful with the rinse wth water thing, which - as I can see - bothers a lot of newbies here. The key is, which I think will help you out is emphesising some small and vital details:
- using as thick foil as possible is a must, forget supermarket foils, although sometimes thicker foils can be found there too. I have ordered Al foil online, with a known thickness, I think it is about 25 microns. This makes Amalgamation MUCH slower, so you have more time to choose the right moment and even prepare other ingredients if you haven`t already done so.
- The foil does not necessarily need to be coffee ground, although I haven`t done a comparison, my yields were close to 80%.
- Be quick with the rinse, and don`t use too much water. I have only tried one rinse.
- Speed: add water quickly, do a couple of shakes and quicly filter it.
- When you have the Amalgamated foil, add your reagents/precursors and monitor what is happening. Do not use ice water bath to cool it at this stage. The reaction will start less violently and after a few seconds, so you have more time to attach the condenser without inhaling too much gas.
- Wait until the reaction has definitely started and is almost starting to get out of hand (but don`t wait too long either until it starst to boil over otherwise you will KILL your reaction. Basically wait until there i bubbling and the flask is getting very hot, then start cooling it .
- I cut up 45g of foil amd it wasn`t to much, the size was around half a small match box size. Add the cut up foil to the flask immediately.
- With this method I reached about 80%, I didn`t calculate the exact yield but it was quite good amount.
= I used HgCl2 instead of HgNO3, but I don`t think this is imporrant.
- Using f two condenserrs I reduced 35g P2NP in a 2 L flask, I will try to scale up when I have a larger flask. E.g. 70g in a 5l flask, the reagent/flask size is probably not linear.
- I have tried one quick wash only and this woked fan1tastic. I recommend this to others too, then try and increase the number of rinses.

In summary: thickness of foil is important, especially as a beginner and not to cool it straight away; it is also important to be patient and wait until all the foil goes to the surface, don`t be too fast as this takes longer, but you have also a bigger window of opportunity.

Can this be used to substitute syntheses requiring NaBH4? I am trying to make 5-MeO-DMT from 5-MeO-T following Hamilton Norris's synthesis, but I don't have NaBH4 available to me.

is there a way to make NaBH4 that doesn't require super high temperatures or pressure and that can be done small scale in an amateur lab, or do I just give up and order from China and hope customs don't question me?
farukhocaogluHello, it would worth to buy. You won't make it without special equipment and appropriate lab experience+skills.
