Esto fue lo que hice a menor escala;
1. 1. Se añadió una solución IPA/H2O 2:1 ((IPA 800ml,H2O 400ml)(1200ml)) a un matraz de 2000ml.
2. 2. Se añadió NaBH4 (116 g) de una vez y se empezó a agitar.
3. Se añadió P2NP (67 g) en pequeñas porciones, para que la temperatura de la mezcla no superara 60 *С.
4. Se añadió CuCl2 (7 g) en agua (13 ml) lentamente gota a gota, de modo que la temperatura de la mezcla no superara 80 *С.
5. A continuación, la reacción se sometió a reflujo a 80 °C durante 30 minutos mediante calentamiento externo.
6. La solución se decanta y se filtra de los residuos de reacción y se pone en un embudo seperatorio.
7. Se añadió una solución acuosa de NaOH al 25% (533 ml) a la mezcla de reacción y se separaron las fases.
8. Se escurre la capa inferior a un vaso de precipitados grande y se recoge la capa orgánica superior.
9. 9. La fase acuosa se introdujo en el embudo de decantación y se extrajo con 500 ml de IPA.
10.El IPA se evaporó en 3/4 partes, mitad freebase lechosa y mitad IPA.
11.El IPA y la freebase se disolvieron en 130ml de acetona.
12.Se goteó ácido ortofosfórico hasta pH - 6 (con agitación constante).
13.La mezcla se puso en el congelador durante 12 horas.
14.Después de la cristalización, la suspensión se filtró y se lavó con acetona fría seca, hasta que la acetona esté limpia.
15.La acetona del lavado y la mezcla de ipa/acetona se colocan de nuevo en el congelador para una nueva precipitación.
16. El proceso se repite hasta que ya no hay precipitados y se obtiene un 60-70% de anfetamina de alta calidad. A medida que la mezcla contiene más acetona, puede ser necesario añadir un poco más de ácido para reducirla, pero no demasiado, ya que la acetona tiene un pH 7.

Aquí hay una foto de algunas de las rocas de pasta seca, el resto es polvo seco para ser mezclado, ya que es demasiado fuerte para mí y mis amigos.
Puede que actualice la receta y escriba un artículo para el químico casero a pequeña escala, hay muchas maneras en que esto podría ser mejor.

esto no es metanfetamina , se puede escribir desde aqui sobre como hacerla a la metanfetamina cristalina

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

Hola. El CuCl2 funciona como catalizador en esta reacción. ¿Necesita una explicación más detallada?

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.

Hola,

Pregunta,

Cuando el aceite de anfetamina se cristaliza con ácido sulfúrico, es el momento de filtrar la anfetamina con un embudo de Buchner, mi pregunta es. ¿Qué tipo de papel de filtración se recomienda para esto?

Por ejemplo, estoy mirando un filtro con las siguientes propiedades, ¿es una buena recomendación?

Propiedades del filtro:
Papeles de filtro de papel de seda
Filtros duros - tiempo de filtración 140 segundos (Retención> 2 µm). Filtración lenta.
Filtros densos para sedimentos finos y muy finos.
Peso: 85 g / m2.
Grosor: 0,17 mm.
Tiempo de filtración: 140 s.
Retención:> 2 µm.


Saludos cordiales

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).

buena pregunta... yo también estoy interesado...
actualmente uso esto

pero no sé lo que es lol

he visto muchos tipos de filtro "cualitativo" o "cuantitativo" y en cada categoria una version "lenta" "media" y "rapida"...
¿cuál es el mejor? :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.
