Synthesis of amphetamine from P2NP via Al/Hg

[malayboy]

I followed the video and read through entire instruction, when I reach the point of inserting mercury nitrate solution, 5ml (from 2g Hg + 15ml nitric acid 68%), then 1 liter of cold water, I then got the result like the video, cloudy gray water and some aluminium foil rinsed up, as the video and instruction mentioned is advised to add more water after first drain, and to repeat the drain process, so i add another 1 liter of cold water

Unexpected issue:
1. it turns cloudy gray again and looks more thicker mixture than the beginning
2. then it started bigger bubbles
3. it has more heat now i tried to touch it, so I pour out again and add the third 1 liter of cold water
4. 3 mins after I pour out all the cloudy gray water, the aluminium foil react itself and produce smoke cover entire lab, the flask is so cold and has water droplets on the flask surface

should I pour P2NP solution directly after the first cloudy gray water drain? because the later reaction seems like the reactions of adding P2NP in the video

No problem, the amalgam is ready, and you can pour a solution of phenylnitropropene.
Or, to gain experience with the first synthesis, you can not wash from mercury salts in order to clearly see the process of the chemical reaction

i had successfully reach the stage on all foil rise up and covered with small bubbles, in cloudy gray water

then I drain the water from it through a fine sieve

then instructions say advisable to add water again in order to rinse the amalgam from residues of mercury nitrate

so I added cold tap water, the reaction started to get more and bigger bubbles, and that is how the mass goes wrong

so I having thoughts on this stage:

1. if the amalgam is ready, shouldn't drain out and add more cold distilled water to rinse out residues of mercury nitrate?

2. if we need to rinse out the mercury nitrate, I should add cold distilled water, yes?

Must drain, and pour quickly a fresh portion of clean water. But if there is little experience, do the first reactions without additional washing.
Not necessarily ice water, the main thing is pure (drinking) water

 

[malayboy]

many thanks to your reply sir, will get a few experiments again

Hello, anyone here who can scale me this Synthese from Amphetamin to P2NP via Al/Hg larger?
I need it for 500g amaphetamin sulfat each process.
Kind regards

Have you also just run out of battery in your calculator, or do you not know how to calculate it?
I can give you some advice, one mole of P2NP theoretically becomes one mole of freebase and with half a mole of sulfuric acid we get half a mole of sulfate. The actual percentage yield is calculated using this theory. The rest should be a walk in the park.

Question about the process:

When the P2nP mix i added with the amalgam and the exothermic process begins.

1 - Does the mix need to stay at a certain temperature during this synthesis or can it be cooled and stirred during this process?

2 - Does the mix need to be contained so that the vape get condensated back in to the mix or can the procedure be made in an open barrel as well, question is related to larger batches P2nP 500g-1000g+.

3 - If multiple batches are made but during different times, is it possible to store the freebase from each batch in a glascontainer for later use or will it "go bad" ?

Thank You

The mix must be cooled at beginning because of strong exothermic reaction, try to get and hold the mix at 60°C. btw. at 95°C you have a volcano.
You should use something like a condenser because the IPA evaporates very fast due to the exothermic reaction. btw. I would never use such a high amount of P2NP, because I think that already 50g P2NP is hard to handle. Be warned and take care of yourself
I can't say for sure, but I've heard that the freebase is not very stable and degrades over time. Avoid heat, air, light and oxygen in any case.

 

[G.Patton]

Keep it at 55-60 degrees C during reaction is going on.
you will lose a lot of solvent without reflux condenser
You shouldn't. It will be oxidized by oxigen from air. Also, light have influence as well. You can try to keep some quantity for some time in dark glass and freezer but you have to distill it before further synthesis.

 

[MrSung]

I don't think you will be able to handle 500g of P2NP, the reaction is very exothermic. I will advice you to start small with something like 10-40g and until you master the procedure then you can slowly increase if you are really into serious business. You have to crawl before you walk, with 500g means you wanna run

 

[Taimo]

okay, then i make it smaller for the first times. On weekend i can start

One question:

Why the fuck are you using thin aluminum cooking foil instead of solid pieces cut from non-elastic aluminum plate?

It doesn't make any sense letting everything get destroyed and let it solute in the mix instead of when you can get everything out after reaction..

 

[WillD]

Show us how this reaction goes, and most importantly, how fast.
