Zde bylo to, co jsem udělal v menším měřítku;
1. Roztok IPA/H2O 2:1 ((IPA 800ml,H2O 400ml)(1200ml)) byl přidán do 2000ml baňky.
2. NaBH4 (116 g) byl přidán najednou a začalo se míchat.
3. P2NP (67 g) byl přidáván po malých dávkách tak, aby teplota směsi nepřesáhla 60 *С.
4. CuCl2 (7 g) ve vodě (13 ml) byl přidáván pomalu po kapkách tak, aby teplota směsi nepřesáhla 80 *С.
5. Poté byla reakce refluxována při 80 °C po dobu 30 minut za použití vnějšího ohřevu.
6. Roztok se dekantoval a odfiltroval z reakčního odpadu a vložil do separační nálevky.
7. K reakční směsi byl přidán 25% vodný roztok NaOH (533 ml) a fáze byly odděleny.
8. Spodní vrstva se odsaje do velké kádinky a shromáždí se vrchní organická vrstva.
9. Vodná fáze byla poté vložena do separační nálevky a extrahována 500 ml IPA.
10. IPA byla odpařena ze 3/4, polovina mléčné volné báze a polovina IPA.
11. IPA a freebase byly rozpuštěny ve 130 ml acetonu.
12.Kyselina orthofosforečná se nakapala na pH - 6 (za stálého míchání).
13.Směs byla vložena na 12 hodin do mrazničky.
14.Po krystalizaci byla suspenze přefiltrována a promyta suchým studeným acetonem, dokud nebyl aceton čistý.
15.Aceton z promývání a směs ipa/aceton se vložily zpět do mrazničky pro další srážení.
16. Proces se opakuje, dokud se již nesráží, aby se získalo 60-70 % vysoce kvalitního amfetaminu, jak se do směsi dostává více acetonu, může být nutné nakapat ještě trochu kyseliny, aby se snížil, ale ne příliš, protože aceton má ph7.

Tady je fotka části vysušených pastovitých kamenů , zbytek je suchý prášek, který je třeba smíchat, protože je pro mě a mé přátele příliš silný.
Možná recept aktualizuji a napíšu pro drobné domácí chemiky, je spousta způsobů, jak by to mohlo být lepší.

Tohle není metamfetamin , můžete odtud napsat, jak se z toho dělá metamfetamin.

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

Ahoj. CuCl2 funguje v této reakci jako katalyzátor. Potřebujete podrobnější vysvětlení?

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.

A jaké % kyseliny sírové by mělo být použito?

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.

Dobrý den,

Otázka: Jaký je váš názor na chemii?

Když je amfetaminový olej krystalizován kyselinou sírovou, je čas odfiltrovat amfetamin pomocí Buchnerovy nálevky, můj dotaz zní. Jaký typ filtračního papíru se k tomu doporučuje?

Dívám se například na filtr s následujícími vlastnostmi, je to dobré doporučení?

Vlastnosti filtru:
Filtrační papíry z hedvábného papíru
Tvrdé filtry - doba filtrace 140 sekund (Retence> 2 µm). Pomalá filtrace.
Husté filtry pro jemné a velmi jemné sedimenty.
Hmotnost: 85 g/m2.
Tloušťka: 0,17 mm.
Doba filtrace: 140 s.
Retence:> 2 µm.


S pozdravem

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).

Dobrá otázka... taky mě to zajímá...
ve skutečnosti používám toto

ale nevím, co to je lol

Viděl jsem spoustu typů filtrů "kvalitativní" nebo "kvantitativní" a v každé kategorii verze "pomalé" "střední" a "rychlé"...
Jaká je nejlepší ? :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.
