Sinteza amfetaminei din P2NP prin Al/Hg (video)

[ch3wbacca]

Adăugarea mercurului metalic la acid nitric 50% și neinhalarea vaporilor, apoi utilizarea acestuia pentru amalgamarea Al în apă sau alcool.
Funcționează întotdeauna, fiabil și rapid.
Dacă acesta este acum nitratul (I) sau (II), mărturisesc că nu m-am gândit niciodată la el.

Dar toate sărurile de mercur funcționează, solubilitatea este secundară. Mercurul singur nu prea dă lovitura, dar niște acid nitric sau niște HCl și un vârf de cuțit de nitrat îl ajută să pornească la drum.

Amalgamarea este o prăjitură din partea mercurului, iar problemele puse pe seama mercurului sunt, practic, întotdeauna puse pe seama aluminiului, în special a foliei stupide care este încă considerată adecvată.
Achiziționați niște granule bune de aluminiu 99,9% și amalgamarea va fi cea mai mică dintre problemele dumneavoastră, iar întreaga reacție va fi, cel mai probabil, fără probleme.

Funktioniert pulver auch solamge die reinheit ausreichend ist oder sollte man granulat nutzen?

 

[Marvin "Popcorn" Sutton]

Din experiența mea, folia de aluminiu este cea mai bună formă de aluminiu pentru amalgam. Condiția principală este ca aceasta să nu conțină componente străine, doar 99,9% Al. Pulberea și granulele de aluminiu sunt, de asemenea, potrivite, dar se recomandă să fie luate în cantități mai mari pentru reacție, iar randamentul nu va fi la fel de bun ca în cazul utilizării foliei.

Este necesar să se producă hidrogen H2 gazos. Puteți citi despre reacție în acest subiect.

Puteți. Este mai bine să folosiți hidrogen alimentar.

On one of the amalgam videos on this site it say when the amalgam is ready hydrogen evolution stops... I am having a big issue on telling when the amalgam is ready. One person said when it all floats another when it's a rich gray.... there has to be a better way to tell. I have waited until gas evolution stops and it never does.. the aluminum just gets completely consumed. I have tried thin and thick foil and aluminum grains. I have tried cleaning with hydroxide prior also. I have gotten the reaction to work a couple times out of at least 50+.... I'm stubborn. Most of the time the p2np is definitely consumed but come out with very very weak effects... actually nothing really as a very light orange solution. The time it did work it came out a dark orange solution. It's absolutely an issue with the amalgam because I have tried so many times I am very familiar with each stage. I find when it reacts very abruptly when the p2np solution is poured in i know it will be a decent reaction. When I have to shake it a lot to get it started it doesn't really work at all.
Does anyone know ow what the symptoms of using to much or to little mercury are so I can try to figure out the issue. I am using the solution of mercury that is described on this site to make mercury ii nitrate but using it as a solution and not dehydrating it as a salt. It says take like 1.5 grams of mercury and 20mls of concentrated nitric acid and wait till the mercury dissolves. Then add 5mls to 12 grams of aluminum. So I'm guessing you would use let's say 2.5ml for 6 grams of foil? There's something escaping me and I can't figure it out help please....

 

[golab071]

It may not be the optimal solution, but it is possible to combine the reduction reaction with amalgamation in a single step

 

[G.Patton]

As I already answered you in DM, you need to get grey amalgam. You don't need to wait until it will be completely dissolved. In the video, it's clearly shown how it should look like. Simple Al foil from a hardware or grocery store.

 

[waltjr5858]

I've seen the video a good 100 times still hard to tell when to do it... I'll figure it out at some point...

Guys, silly question can ga acid be substituted with another acid or OTC cheat .i have all other requirements n was keen to play around see wat I CLD fuk up on it but am stumped not having any of the glacial

 

[rampage]

hey mate i can help you where to get gaa?

I had a failed first attempt and kinda fucked up big time by inhaling toxic fumes from the violent reaction.

As I poured the P2NP solution into the flask, the funnel on the flask couldn't hold itself and started bouncing (simply because of vapor pressure from the reaction). It happened so quickly that I couldn't find any time to process what's happening and to put a condenser. As a result, I inhaled some toxic fumes from the reaction and I'm not exactly sure how toxic they were but it smelled so bad. Some solution got spilled as a result and the reactants got evaporated in the early stage.

The yield from my 10g setup was like 300mg of white salt(turned out it was some basic byproduct or unreacted amphemine freebase). It tasted like a soap and had a burning sensation so I threw it away. 5-6% yield was a red sign anyway.

Some mistakes that I made that newbies can avoid:
1. Don't use a small funnel on flask: When pouring the P2NP solution in the amalgam, make sure your funnel's stem is big enough (especially w/ a >=10g setup). Smaller stem/funnel size in general can be a bottleneck and cause spillage or other adverse outcomes (you have to be very quick here to add a condenser and shake the flask).

2. Make sure you don't evaporate the solvents in the P2NP+IPA+GAA solution while heating it. Sometimes P2NP crystals may not dissolve so gentle heating may help(40-50'C) but if you heat it more then solvents like IPA would begin to evaporate and you'd lose solvents.

3. Ensure that your water is distilled and has close to zero TDS. I bought some "destilled water" bottles but they turned out to be just purified water with a 25-30 TDS. It's not a significant issue but contaminated water should be avoided in the amalgam phase to avoid unnecessary reactions with water impurities.

4. Properly acidify the amphetamine freebase before proceeding for drying. My pH papers were shit so I couldn't measure properly but you shouldn't stop before a pH of 6. Keep adding more acid solution until you reach it. Mistakes at this stage can result in a basic soapy product, not amphetamine sulfate.

5. Extract your amphetamine freebase with a non-polar solvent. The video doesn't include this part but it's an important step to not miss if you want a successful and pure yield. Something like Toluene could work. I haven't tried this it before but next time I'm going to do this.

6. If it's your first time, be very careful with the exothermic reaction when adding P2NP solution to the amalgam. In reality it can be far more violent than what's shown in the video so be prepared for that. Proper PPE and preparation can help like keeping cold water and condenser handy.

---

I have a few questions here for the experienced chemists:
1. How to deal with solvents volume loss? Even after a condenser and ice-baths, sometimes it can evaporate more. At what stage are we safe to add some IPA to the mixture? The video descriptions says you can add some IPA after the reaction is complete(to rinse the flask). Is that correct and if yes, how much are we talking at this scale? 15-20ml?

2. Can we add the P2NP solution slowly and in batches instead of at once? I can see this can result in more solvent evaporation but I really want to avoid overheating and violent reaction.

 

[G.Patton]

You had to use simple PPE like face mask. It's sad to read. I wrote a topic about PPE. It's cheap and may save you from poisoning.
This overheating means that you spoiled your P2NP. That is the reason of low yield.
Just add more at the beginning of the reaction. Yes, 20-30 ml more would be enough.
Yes, you can split P2NP solution in several portions.

Hello friend, can you tell me if in the synthesis of Al/Hg after the reaction of p2np with al I added too much NaOH and instead of pH 12 I got 9.5 10 or is this a bad oil A?

 

[nofuckups]

I believe you need to keep adding more NaOH to it until it reaches pH12 or more.

 

[G.Patton]

It's correct.

 

[NieDoswiadczony]

this means that if I add more, I don't go down in pH

 

[nofuckups]

you should the very basics of chemistry like pH. High pH means it is basic.

 

[G.Patton]

More NaOH solution, higher pH.

 

[NieDoswiadczony]

in the synthesis of Al/Hg it is written to make 10gP2, e.g. 100ml IPA, 50ml acetic acid and in the film there is also 50ml H2o added

 

[golab071]

You only add water if you’re using concentrated acetic acid. You can use 80% acetic essence.


50 ml GAA (Glacial Acetic Acid) = ~62 ml of 80% acetic essence.

 

[NieDoswiadczony]

and if I use 99% acetic acid and do not add water, will the reaction be bad?

 

[NieDoswiadczony]

and if I use 99% acetic acid and do not add water, will the reaction be bad?

 

[golab071]

The aluminum amalgam needs some water to function effectively because the reaction Al + H⁺ → H₂ proceeds faster in the presence of water.

In a completely anhydrous environment of IPA + 99% acetic acid, the reaction may slow down or not start at all.
Have you already tried carrying out the reaction? How’s it going?

 

[nofuckups]

how much water exactly? Isn't the leftover water on foil after rinsing sufficient? I use >99% GAA and IPA so I'm wondering if i should add some water to this solution. For a 10g scale, what quanity of water should be added if any? Do we actually need to add water if the foil is wet?

 

[waltjr5858]

Hydrogen actually is bad for the reaction. The reaction takes place on the aluminum surface with the mercury mediating the electron transfer. There's also something else happening to do with protons and a radical something but I forgot the rest. But... hydrogen is coming no matter what obviously.

 

[NieDoswiadczony]

yes I tried and after pouring a short delay of about 40 seconds and everything goes normally the temperature increases it needs cooling with ice water everything dissolves when straining the mixture on a sieve you can see a few small pieces, after adding NaOH to pH 12 I get a slightly yellow oil

 

[NieDoswiadczony]

and the smell is a bit hard to describe, like a mix of alcohol and rotting fish

 

[rampage]

for me its been between 10-15minutes for amalgam to be ready, not sure how long fellow members do it for

 

[waltjr5858]

How do you tell when the amalgam is ready and what temperature do you keep it below? I find that when trying to keep it below 60c the reaction almost dies out.... also the timing of the p2np addition... typically when I add it nothing happens except the temperature starts climbing until it gets over 60c and then it goes crazy. I can tell the amalgam isn't fully ready or I'm too late. The reactions that work when just like the video it starts reacting like crazy the second the p2np hits the aluminum. Mine has to be shaken for a while and then starts going in like 20 seconds or so. Also is the reaction complete when the reaction settles down or does it need some time on the hot plate at the end?

 

[NieDoswiadczony]

what could be the reason that I can't get ph 12 I have broken down NaOh 50g into 75ml of water 100g into 120ml of water and I can't get ph 12
