Dobrý deň všetkým. Pokúsil som sa v malom meradle vyrobiť amfetamín podľa tohto receptu, ale nepodarilo sa mi to. Všetko sa zdalo byť v poriadku, po vysušení môj produkt vyzeral ako biely prášok s nádychom červenej farby. Ak by to bol amfetamín sulfát (ktorý som sa snažil vyrobiť), výťažok by bol 84 %. Problém je, že to nie je amfetamín.

Fyziologické účinky
Skúsil som 20-30 mg, určite došlo k stimulácii, ale tiež to spôsobilo horúčku a zrejme aj pokles imunity: v oboch prípadoch, keď som ho užíval niekoľko dní po sebe, som ochorel na infekcie dýchacích ciest (prvýkrát som si myslel, že je to náhoda). Iná osoba, ktorá ho užívala, nepociťovala žiadnu stimuláciu od dávky do 90 mg, len určité sucho v ústach. Ani jeden z nás nemá žiadnu toleranciu na stimulanty.

Chemické testovanie
1 g prášku sa úplne rozpustí v 10 ml H2O.
Keď som k odmeranej hmotnosti prášku v skúmavke pridal prebytočný roztok NaOH, dostal som približne správny objem voľnej bázy s vôňou amoniaku. Oddelil som vrstvu freebázy, vysušil som ju CaCl2 a skúsil som ju titrovať kyselinou. Výsledkom bolo, že som nameral molárnu hmotnosť freebázy približne 171 (a pre amfetamín je to 135). Hoci moje merania neboli veľmi presné, rozdiel je stále príliš veľký na to, aby sa dal vysvetliť len chybami merania.

Moje odchýlky od postupu

1) Pri pridávaní P2NP som si uvedomil, že to bude trvať hodiny, takže som bol netrpezlivý a ponoril som reakčnú banku do vodného kúpeľa s izbovou teplotou. Potom sa mi podarilo pridať P2NP takmer naraz a teplota zmesi neprekročila 40 - 50 °C.
2) Postupoval som podľa videa, takže som neodparil IPA a pridal som konk. kyselinu sírovú priamo do vrstvy IPA/freebase.
3) Momentálne som nemal acetón, takže som ho pred okyslením nepridal a prefiltrovanú "amfetamín sulfátovú" pastu som premyl IPA.
4) IPA je menej prchavá ako acetón, takže som musel dať svoju zrazeninu na niekoľko hodín do rúry, aby som ju vysušil na konštantnú hmotnosť. Teplota v sušičke neprekročila 80 °C.

Takže hlavná otázka znie, kde sa stala chyba? Neprekvapil by ma nízky výťažok alebo žiadny produkt, ale získať dobrý výťažok amínu, ktorý nie je amfetamín?!

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

What is the salt of amphetamine present on this photos?

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.
