Síntese de anfetamina em um único recipiente a partir de P2NP com NaBH4/CuCl2 (escala de 1kg)

Placa de aquecimento, manta de aquecimento (pode ser demasiado, mesmo em lume brando), mas não uma chama aberta.

Was ist die beste low budget alternative zu einem 600€ heizmantel?

 

[btcboss2022]

100% de certeza que no próximo lote de gramas vou fazer fotos. Obtive 254gr de freebase a partir de 287gr de P2NP.

Wie viel war es in flüssiger form?

 

[Montecristo]

não consegui precipitar muito sal quando adicionei ácido fosfórico no meu lote de 67g de p2np.
Isto vai mudar durante o congelamento? pensei que tinha seguido as instruções muito bem.
depois da adição de p2np estar completa, passa-se diretamente para o cucl? ou devo esperar que pare de reagir?
agitei-o depois de adicionar a lixívia e deixei-o durante cerca de uma hora, e ao extrair com ipa deixei-o separar-se e depois misturei novamente 3/4 vezes.
destilei o ipa no vácuo a 50-60oC, será que estava demasiado quente?
talvez tenha acidificado demasiado rápido, uma vez que o meu funil de separação ainda tinha a camada aquosa (estou a fazer 2 extracções de ipa por precaução), por isso usei uma seringa e não foi exatamente gota a gota...
alguma ideia? actualizarei a situação depois de ter estado no congelador durante a noite

Habe es auch versaut beim ersten mal gucke grad nach lösungen und schließe mögliche fehler aus. Hat sich bei dir auch nur ein kleiner teil umgewandelt und es ist größtenteils flüssig geblieben?

Was your freebase purified? This reaction produces quite alot by-products so it's absolutely required to steam distill the freebase. Put 1ml freebase oil on petri dish and let evaporate. If the residue is not white it's not pure. If it's not pure and you turn it to salt, your power doesn't dissolve in water easily and yoy'll get sick if you take it.
So this was the boiling temp in the flask or bath temp? Not sure if too hot when I did it the BP was ~38 C while the water bath was kept < 60 C. (The BP only depends on pressure so higher bath temp. only makes it boil more violenly at same temp.) Do normal distillation of your vacuum distillate and see if anything solid remains in boil flask.
Might be dissolved in the water in it.

 

[Johnny Ringo]

Good to know the destillation is essential for this process thanks. I kept the oil and will try to purify it with destillation and see what comes out.

O que é que eu sei é que o ácido sulfúrico é muito puro, mas o meu ácido é muito puro.
Se estiveres na UE, encomenda na Polónia, eles vendem-te barris de literalmente qualquer coisa lol

 

[Johnny Ringo]

Darfst du mir hier verraten woher du die schwefelsäure beziehst oder muss ich dir privat schreiben? Habe grad probleme welche zu beschaffen nur phosphorsäure iaz für mich aktuell laufend zugänglich.

Hello, if you wanna get answer, use English in this section please. You also can post your questions in Germany section in your native language.

You will actually be surprised you do not need a very powerful pump and determining what suction you are running at is a pain in the ass. I actually have a very good vacuum gauge that I hook directly up to my system and test boiling temperatures of known substances and it's still a little all over the place. I think the best thing you can do is steam distillation If the product allows because it does come over nice and clean and then just dry it with potassium carbonate and you are in business. Definitely do not buy a rotary vein vacuum pump because I have destroyed probably five of those things. They are very powerful and I can boil water below room temperature easily but without inexpensive setup I do not have a way to regulate vacuum pressure. If you crack open a small leak on purpose to lower the pressure what that causes is air now flowing through the system instead of sitting at a vacuum which causes your product to go right into a trap or right into the vacuum pump and gone. Any kind of oil that can be steam distilled is absolutely worth the time it takes. If you definitely need vacuum they sell some on Amazon and they are called diaphragm pumps I believe and require no oil so there's no way for you to contaminate the vacuum pump when you do distillation. Just pump away and they definitely go low enough to let's say take a 200° C boiling temp and get it close to just a little over 100 so plenty low enough and definitely worth it over the rotary vein. I think they cost just a tiny bit extra nothing crazy. That was probably the best purchase I ever made as a vacuum pump after blowing up five of the other ones

I have question about vacuum distillation.

In order to achieve vacuum, my compressor has to run all the time to create good vacuum and tight sealing.

1. Is simple distillation with flask and reflux condenser fine or should I use fractional column like in alcohols, although in this video simple is enough

2. Does your IPA evaporate through vacuum pump instead in receiving flask since all air is sucked through vacuum out because unit runs all the time?

3. Why flasks need to be round bottomed, I have erlenmayer flask as receiving and I don't see reason why I should replace it with round bottom?

4. I also created moonshine, can you tell how to dillute % of ABV, water or distilled water makes it look less crystal clear.

Thanks

Hi. Can someone tell me what the cost of ingredients and equipment for producing 1kg is? I would be grateful if someone could tell me if it is enough to scaling up everything to get a larger amout or does that cause any discrepancies? Also can someone tell me what is the CAS of this final product?

It would be really REALLY great if someone could run a TLC analysis of the products from this reaction. I've read that NaBH4/Cu reduction mainly produces N-hydroxylamines instead of amines for alpha-alkyl nitrostyrenes. Because of similar melting points for their salts and similar boiling points, the only way to separate and identify N-OH-amphetamine is by chromatography. The N-OH product is also active as a stimulant but it is different to amphetamine. I wonder if this is really true.

 

[GhostChemist]

what source reports this information?
all compounds tested with qualitative and quantitative analysis
N-OH group can be formed as an intermediate compound if the experiment is not carried out correctly

 

[OneTensionSkyRed]

Yes, I should have probably researched this a little more before posting here, apologies. The source for this comes from amateur chemists and there aren't any official publications to support this

 

[Chemical Dream]

Is so much NaBH4 really necessary or is it excessive

 

[mile123]

Vacuum distillation can be avoided, final product may contain IPA, without NaBH4 you can't get final product at all. It is base ingredient along P2NP

So. You get this pure amphetamine. How much would you cut it ? 1kg amph turn to 2kg ? Because amph cheap profit should come from cutting it or I am wrong?

 

[GhostChemist]

Our team is study science methods for obtain only pure individual substances. We do not support and do not give recommendations for dilution this compounds to increase mass, yields

Am I the only one who sees a lot of impurities here?

 

[adhdcurse]

Hello Guys. Can someone please post here what chemicals exactly form in each reaction, step by step. I am trying to understand each step. There are several steps where it is not documented what chemicals are actually created. I am trying to use a Chemical Reaction Simulator/Modelling Software, like Aspen Plus, HYSYS, COPASI, Chemcad, Matlab, Cantera, COCO etc.
