Amfetamino sintezė iš P2NP naudojant NaBH4/CuCl2 iš vieno puodo (1 kg skalė)

[SelfExper1menter]

Sveiki visi. Bandžiau pagal šį receptą nedideliu mastu pasigaminti šiek tiek amfetamino, bet nepavyko. Viskas atrodė gerai, išdžiūvus mano produktas atrodė kaip balti milteliai su raudonumo atspalviu. Jei tai būtų amfetamino sulfatas (kurį bandžiau pagaminti), išeiga būtų 84 %. Problema ta, kad tai ne amfetaminas.

Fiziologinis poveikis
Išbandžiau 20-30 mg, stimuliacija neabejotinai buvo, bet taip pat sukėlė karščiavimą ir, matyt, imuniteto susilpnėjimą: abu kartus, kai vartojau kelias dienas iš eilės, susirgau kvėpavimo takų infekcijomis (pirmą kartą maniau, kad tai sutapimas). Kitas jį vartojęs asmuo nepatyrė jokio stimuliavimo nuo iki 90 mg, tik šiek tiek džiūvo burna. Nė vienas iš mūsų neturime jokios tolerancijos stimuliantams.

Cheminiai tyrimai
1 g miltelių visiškai ištirpsta 10 ml H2O.
Į mėgintuvėlį įpylus perteklinio NaOH tirpalo į išmatuotą miltelių masę, gavau maždaug teisingą laisvosios bazės, turinčios amoniako kvapą, tūrį. Atskyriau laisvosios bazės sluoksnį, išdžiovinau jį CaCl2 ir pabandžiau titruoti rūgštimi. Rezultate išmatavau, kad frebazės molinė masė yra maždaug 171 (o amfetamino - 135). Nors mano matavimai nebuvo labai tikslūs, skirtumas vis tiek yra per didelis, kad jį būtų galima paaiškinti vien matavimo paklaidomis.

Mano nukrypimai nuo procedūros
1) Pridėdamas P2NP supratau, kad tai užtruks kelias valandas, todėl tapau nekantrus ir panardinau reakcijos kolbą į kambario temperatūros vandens vonią. Po to P2NP galėjau pridėti beveik visą vienu metu, o mišinio temperatūra neviršijo 40-50 °C.
2) Vadovavausi vaizdo įrašu, todėl neišgarinau IPA ir tiesiai į IPA ir (arba) freebazės sluoksnį įpyliau konc. sieros rūgšties.
3) Šiuo metu neturėjau acetono, todėl prieš parūgštinimą jo nepridėjau, o filtruotą "amfetamino sulfato" pastą nuploviau IPA.
4) IPA yra mažiau laki nei acetonas, todėl savo nuosėdas turėjau kelioms valandoms įdėti į orkaitę, kad išdžiūtų iki pastovaus svorio. Temperatūra orkaitėje neviršijo 80 °C.

Taigi, pagrindinis klausimas, kur nutiko klaida? Nenustebčiau, jei išeiga būtų nedidelė arba produkto visai nebūtų, bet gauti gerą amino, kuris nėra amfetaminas, išeigą?!

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.

CaCl2 negalima naudoti su aminais
1. pirmajame etape nitropropenas redukuojamas į nitropropaną
2.gauta įvairių druskų priemaišų į amfetamino pastos sudėtį

Chemical testing
The acid concentration must be precisely known (titration with standart solution of NaOH).
In the titrimetric analysis the concentration must be used only in equivalent concentration or normality or molality.
If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular and the pH shifts less with small additions of titrant near the equivalence point. Indicators such as Methyl red or Litmus should give more accurate results
This method cannot be applied in this implementation

I tried this synthesis on a small scale.
It failed completely. In the end I didn't even receive A-Oil.

This was my path:

p2np 10g

IPA/H2O (1:2) IPA 120ml/H2O 60ml (180ml)

NaBH4 17.4g

CuSO4.5H2O 7.9g in 20ml H2O

NaOH 25.6g in 80ml H2O

First water and then IPA were filled into the flask at room temperature and stirred.

NaBH4 was completely filled into the flask and stirred overhead.

p2np was added over a period of 30 min.
The temperature did not rise above 45 degrees.

When all P2NP was in the flask I increased the temperature to 55-58 degrees and refluxed for 40 minutes.

Then CuSO4.5H2O
dropped into the flask. Black copper immediately formed
Somehow the temperature didn't increase.

The RM was heated in a water bath to 78-80 degrees for 30 minutes.

The flask was left at room temperature for 1 hour.

There were 2 layers in the flask, black copper at the bottom. 'Amber cloudy at the top.

There was something slightly yellow in between that couldn't be dissolved.

Then 80 ml of 25% NaOH was added to the RM and a dark amber layer became visible.

It didn't smell like amphetamine base,
it smelled very flowery.
Nothing reminiscent of Amphetamine Oil.

Can someone explain what was wrong?
I followed the small scale instructions from this thread

p2np was from BM-chemistry
and looks very clean and bright.
It can't fail because of that.

I'm sorry for the bad English, hope you understand what I want to say.

I know what you mean by the flowery smell but I can't tell you what it is. I have had that exact failure. Even using cucl2. The copper didn't cause your failure... it's something else.

But I do know that no matter what amounts are used as long as you either scale down or scale up preferably from the original video that is up on this site there is a caption that comes up during the video that says you should add the p2np over the course of 6 hours. The only time this reaction has really worked good for me with very strong effects at the end except was still dirty and needed proper cleaning but it worked. Normal stuff water alcohol and borohydride all together and then I took whatever I was using at that time for the substrate p2np and divided it by 24. Whatever that equaled that's how much I added every 15 minutes until it was gone which was 6 hours. I noticed on the last addition that there was no reaction from the nabh4 fornsome reason? Guess I used it all up possibly so I added a half a gram of borohydride just in case. Waited 5 minutes and started dripping the proper amount of cucl2 in. When doing smaller reactions it's really hard to tell if you have added copper until the black particulate stops forming because the flask is small to begin with and the whole damn thing turns black. So as according to the video they used 25 or 26 G to 250 g of p2np so I did a 10 G reaction and it was somewhere around a gram or a little over of copper so I just dripped the entire thing in. Once I was done adding I just cranked the heat until I hit 80c and waited about 35 minutes and allowed it to cool to room temperature and it worked perfect minus being completely contaminated with some kind of Borate.. once I noticed that I just redesolved and acidified to a pH of 3 gave it a wash with nonpolar and then refreebased and gave it a little water wash. Dried it and re-added acid to crash out... it is a finicky reaction and definitely not as easy as most people put it there has to be some kind of trick as to the temperature you put your copper in the reaction or how long to let it react before adding the copper or something there's a trick to make it consistent because I can definitely tell you the aluminum Mercury reaction is very inconsistent even worse than this one
