Olá a todos. Tentei fazer um pouco de anfetamina usando esta receita em pequena escala, mas falhei. Tudo parecia bem, mas depois de secar o meu produto parecia um pó branco com um toque de vermelhidão. Se fosse sulfato de anfetamina (que eu estava a tentar fazer), o rendimento seria de 84%. O problema é que não se trata de anfetamina.

Efeitos fisiológicos
Experimentei 20-30 mg, houve definitivamente estimulação, mas também provocou febre e, aparentemente, uma diminuição da imunidade: das duas vezes que a tomei durante vários dias seguidos, adoeci com infecções respiratórias (da primeira vez pensei que fosse coincidência). Outra pessoa que a tomou não sentiu qualquer estimulação até 90 mg, apenas alguma secura na boca. Nenhum de nós tem tolerância a estimulantes.

Testes químicos
1 g do pó dissolve-se completamente em 10 ml de H2O.
Quando adicionei uma solução de NaOH em excesso a uma massa medida do pó num tubo de ensaio, obtive um volume aproximadamente correto de base livre com cheiro a amoníaco. Separei a camada de base livre, sequei-a com CaCl2 e tentei titulá-la com ácido. Como resultado, medi a massa molar da base livre como sendo cerca de 171 (e para a anfetamina é 135). Embora as minhas medições não tenham sido muito precisas, a diferença é demasiado grande para ser explicada apenas por erros de medição.

Os meus desvios ao procedimento

1) Ao adicionar P2NP, apercebi-me que ia demorar horas, por isso fiquei impaciente e mergulhei o balão de reação num banho de água à temperatura ambiente. Depois disso, consegui adicionar o P2NP quase todo de uma vez, e a temperatura da mistura não ultrapassou 40-50 °С.
2) Eu estava seguindo o vídeo, então eu não evaporei o IPA e adicionei conc. ácido sulfúrico para a camada IPA / freebase diretamente.
3) Eu não tinha acetona no momento, então não a adicionei antes de acidificar e lavei a pasta filtrada de "sulfato de anfetamina" com IPA.
4) O IPA é menos volátil do que a acetona, pelo que tive de colocar o meu precipitado numa estufa durante várias horas para o secar até atingir um peso constante. A temperatura no forno não excedeu 80 ° С.

Então, a grande questão é: onde é que correu mal? Eu não ficaria surpreso com baixo rendimento ou nenhum produto, mas obter um bom rendimento de uma amina que não é anfetamina?

The method as described here lacks all product workup/cleanup and and as such provides a very dirty and unclean Amphetamine, in special as NasBH4 reductions are all not giving very clean product. Purple MDMA and such.
I know the physiological effects like fever like very well and it is just the missing cleaning trust me.
There are several ways to do the workup, from distillation, normal, vacuum or steam of the base or dissolving the sulfate in water and washing this several times with toluene or petrolether or my favorite: 50/50 mix of petrol ether and Ethylacetate. Then evaporate the water and wash the resulting salt with copious amounts of Acetone and petrol ether as last. Already the simple washings give you a consumable product which does not make you sick like the crap which contains borate salts or else.

Even with the dirtiest amp he would have felt it just fine....guaranteed he got "almost amp" mainly riddled with hydroxylamine. This reaction goes south on people all the time. They have wayyyy too much nabh4 left when it's time to add the copper and with the heat the nanoparticles aggregate and become completely useless as a catalyst....fully useless... and leave semi reduced product. The only way I've been able to get around that is by reducing 1st in methanol/thf to propane then extracting and then using anyone of the zinc/formic acid combos.... for the nitro. Zero Michael addition.

I tried it today, but something must have gone wrong..I followed the instructions exactly, but in the end there is more than there should be. What could have happened? Can anyone give me advice? Can it be cleaned? Thank you for every answer

Please. How do I have a reaction more nabh4? I threw in for 6 hours but still not much nabh4 dissolved. In the end, when I added acid, the whole thing thickened after filtration, a white substance remained, but I suppose it's nabh4.. I followed the instructions I don't know what's wrong.

My mescaline guide might help for 1 or 2 mol amounts. Possibly up to 500 g+ in a 20 L reaction vessel.

The same procedure for P2NP as with Mescaline nitrostyrene, however I do not know if it is more reactive. Have not worked with it.

Take a look here:

Or posted here (if starting from benzaldehyde):

My friend and I always cooked amphetamine in the forest.
That is, for synthesis we really only needed 3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons that show the reaction.

My role was always bring and serve, but we produced this product of 99.8% purity.
We had no competition in Moscow :/

we didn't use fucking acetone because it's bad for your health

At one point in Russia, they suddenly cut off the liquid propen supply—left a bunch of wannabe cooks totally clueless. Product turned out nasty as hell, colors ranging from sketchy pinks to filthy yellows and straight-up horrifying oranges. But my homie was different—he was one of the few who knew the synthesis inside and out. Back in the day, he cooked pristine pervitin for the whole block, but dude got busted—hit him with a solid 20-year stretch. Luckily there’s a war poppin' off, so he'll probably get tossed onto the front lines and bounce back home early. Then we'll pick right back up where we left off.

but you say "...3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons..." and in your list of reagents only hydrochloric acid

I can hit him up and get the full cook recipe—it's fuckin' one-of-a-kind.

in this synthesis using only this reagents "...Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons..." amp sulfate cannot be obtained.

with hydrochloric acid obtain amp hydrochloride
with sulphuric acid obtain amp sulphate

Your reagents list remind different synthesis way (Al/Hg approach). Why did you write this post under NaBH4 method? It's, also, interesting about HCl and sulphate salt.
