Här var vad jag gjorde i mindre skala;
1. Lösning IPA/H2O 2:1 ((IPA 800ml,H2O 400ml)(1200ml)) tillsattes en 2000ml kolv.
2. NaBH4 (116 g) tillsattes på en gång och omrörning startades.
3. P2NP (67 g) tillsattes i små portioner, så att blandningens temperatur inte översteg 60 * С.
4. CuCl2 (7 g) i vatten (13 ml) tillsattes långsamt droppvis, så att blandningens temperatur inte översteg 80 *С.
5. Därefter återflödade reaktionen vid 80 °C i 30 minuter med hjälp av extern uppvärmning.
6. Lösningen dekanteras och filtreras från reaktionsavfallet och läggs i en separeringstratt.
7. 25% vattenlösning av NaOH (533 ml) tillsattes till reaktionsblandningen och faserna separerades.
8. Töm bottenskiktet i en stor bägare och samla upp det översta organiska skiktet.
9. Den vattenhaltiga fasen hälldes sedan i en separeringstratt och extraherades med 500 ml IPA.
10. IPA indunstades till 3/4, hälften mjölkig freebase och hälften IPA.
11.IPA och freebase löstes upp i 130 ml aceton.
12.ortofosforsyra droppades till pH - 6 (under konstant omrörning).
13.Blandningen sattes i frysen i 12 timmar.
14. Efter kristallisering filtrerades suspensionen och tvättades med torr kall aceton tills acetonen var ren.
15.Aceton från tvättning och ipa/acetonblandningen placeras tillbaka i frysen för ytterligare utfällning.
16.Processen upprepas tills ingen mer fällning ger 60-70% högkvalitativ amfetamin, eftersom blandningen får mer aceton i den kan du behöva droppa lite mer syra för att få ner den, men inte för mycket eftersom aceton är ph7.

Här är ett foto av några av de torkade pasta stenarna, resten är torrt pulver som ska blandas, eftersom det är för starkt för mig och mina vänner.
Jag kan uppdatera receptet och göra en skrivning för den småskaliga hemkemisten, det finns många sätt som detta kan bli bättre.

A different process. P2P or sudo. Just pick one. But these are safer imo

Hej. CuCl2 fungerar som katalysator i denna reaktion. Behöver du en mer detaljerad förklaring?

I would like to know the entire concept if u k know it. Like how much copper to reduce p2np exactly. Are we making an electron here in this synth? What is going on exactly ? I understand how to run through but not the actual chemical reaction that is happening.

What do you mean?
There is clearly said how much. 105g CuCl2 per 1kg P2NP.

NaBH4 donate hydrogen while this reaction to P2NP and nitrogen atom change its oxidation state from +3 to -3. Hence, it get 6 electrons.

Buy virgin sulfuric from as drain cleaner if u can’t find one with a high purity. I could only find like 20% online for some reason. The drain cleaner is actualy more pure. Like wtf

it's worth to use 96-98%, but you can use less concentrated as well.

Hej, jag har en fråga,

Jag har en fråga,

När amfetaminoljan kristalliseras med svavelsyra är det dags att filtrera ut amfetaminet med en Buchner-tratt, min fråga är. Vilken typ av filtreringspapper rekommenderas för detta?

Till exempel tittar jag på ett filter med följande egenskaper, är detta en bra rekommendation?

Egenskaper för filter:
Filterpapper tillverkade av silkespapper
Hårda filter - filtreringstid 140 sekunder (Retention> 2 µm). Långsam filtrering.
Täta filter för fina och mycket fina sediment.
Vikt: 85 g/m2.
Tjocklek: 0,17 mm.
Filtreringstid: 140 s.
Retention: > 2 µm.


Bästa hälsningar

1. Material:
Generally, tissue paper is not recommended for chemical filtration, especially in organic chemistry, as it may not provide the necessary chemical resistance and could introduce impurities.

3. Retention:
This retention level is suitable for filtering out larger particles, but if the amphetamine salt crystals are smaller than this size, they may pass through the filter. For crystallization processes, you typically want a filter paper that can retain smaller particles, ideally in the range of 1 µm or less.


4. Weight (85 g/m²) and Thickness (0.17 mm):
a relatively dense filter paper, which may be good for fine filtration but could also slow down the process. Thicker filter papers tend to have lower flow rates

Recommendations​

Quantitative Filter Paper:
Look for papers with a retention size of 1 µm or less, which would be more suitable for filtering fine crystals.


Buchner Funnel Filtration:
Whatman filter paper or similar brands that are specifically designed for vacuum filtration. These papers are available in various grades, including those with finer retention capabilities (e.g., Whatman Grade 1 or Grade 2).

bra fråga... jag är också intresserad...
Egentligen använder jag det här

men jag vet inte vad det är lol

Jag såg en hel del typ av filter "kvalitativ" eller "kvantitativ" och i varje kategori en version "långsam" "medium" och "snabb" ...
vad är det bästa? :p

Quantitative Filter Paper
Specification: 9.0 cm
The second image has a table with various specifications, likely describing different types of filter paper based on attributes like thickness, pore size, or filtration speed.

What is a purity of a final 60% - 70% yield? I found that there is such thing as amphetamine paste and amphetamine sulfate and sulfate is x2 in price. What is this final product (124.4g on video)?

a videóban a végső mennyiség szulfát. A paszta konzisztenciája tömeg szerint 3x lehet, mert az oldószerek nem párologtak el. (javítsatok ki, ha tévedek).

Can I do a run of the synth with only 5g p2np ? To get a grip on it first.

You have to! Small scale batch is necessary to carry out several times before large one in order to understand this synthesis and remember it well.

Is 5g p2np okay or too small ? And is pressure required during reaction or just the constant heating ?

Yes, okay. Atmosphere pressure.

Is the pressure required or will it do fine just running hot with no pressure? Do I need to hold as much pressure as possible ? I have a nice 1000ml heavy wall round bottom. So it will hold some, but if it isn’t needed I won’t worry about it.
