Hola a todos. Intenté hacer un poco de anfetamina usando esta receta a pequeña escala, pero fracasé. Todo parecía estar bien, después del secado mi producto parecía polvo blanco con un tinte rojizo. Si se tratara de sulfato de anfetamina (que era lo que intentaba hacer), el rendimiento sería del 84%. El problema es que no es anfetamina.

Efectos fisiológicos
Probé 20-30 mg, definitivamente hubo estimulación, pero también causó fiebre y, aparentemente, una disminución de la inmunidad: las dos veces que lo tomé durante varios días seguidos, caí enfermo con infecciones respiratorias (la primera vez pensé que era una coincidencia). Otra persona que lo tomó no experimentó ningún estímulo con hasta 90 mg, sólo algo de sequedad en la boca. Ninguno de los dos tiene tolerancia a los estimulantes.

Pruebas químicas
1 g del polvo se disuelve completamente en 10 ml de H2O.
Cuando añadí un exceso de solución de NaOH a una masa medida del polvo en un tubo de ensayo, obtuve un volumen aproximadamente correcto de freebase con olor a amoníaco. Separé la capa de base libre, la sequé con CaCl2 e intenté valorarla con ácido. Como resultado, medí que la masa molar del freebase era de aproximadamente 171 (y para la anfetamina es de 135). Aunque mis mediciones no fueron muy precisas, la diferencia es demasiado grande para explicarla únicamente por errores de medición.

Mis desviaciones del procedimiento

1) Al añadir P2NP, me di cuenta de que iba a tardar horas, así que me impacienté y sumergí el matraz de reacción en un baño de agua a temperatura ambiente. Después pude añadir el P2NP casi de una vez, y la temperatura de la mezcla no superó los 40-50 °С.
2) Siguiendo el vídeo, no evaporé el IPA y añadí directamente ácido sulfúrico conc. a la capa de IPA/freebase.
3) No tenía acetona en ese momento, así que no la añadí antes de acidificar y lavé la pasta filtrada de "sulfato de anfetamina" con IPA.
4) El IPA es menos volátil que la acetona, así que tuve que meter mi precipitado en un horno durante varias horas para secarlo hasta peso constante. La temperatura en el horno no superó los 80 °С.

Entonces, la gran pregunta es, ¿dónde salió mal? No me sorprendería que el rendimiento fuera bajo o que no hubiera ningún producto, pero ¿obtener un buen rendimiento de una amina que no es anfetamina?

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.

Even with the dirtiest amp he would have felt it just fine....guaranteed he got "almost amp" mainly riddled with hydroxylamine. This reaction goes south on people all the time. They have wayyyy too much nabh4 left when it's time to add the copper and with the heat the nanoparticles aggregate and become completely useless as a catalyst....fully useless... and leave semi reduced product. The only way I've been able to get around that is by reducing 1st in methanol/thf to propane then extracting and then using anyone of the zinc/formic acid combos.... for the nitro. Zero Michael addition.

I tried it today, but something must have gone wrong..I followed the instructions exactly, but in the end there is more than there should be. What could have happened? Can anyone give me advice? Can it be cleaned? Thank you for every answer

Please. How do I have a reaction more nabh4? I threw in for 6 hours but still not much nabh4 dissolved. In the end, when I added acid, the whole thing thickened after filtration, a white substance remained, but I suppose it's nabh4.. I followed the instructions I don't know what's wrong.

My mescaline guide might help for 1 or 2 mol amounts. Possibly up to 500 g+ in a 20 L reaction vessel.

The same procedure for P2NP as with Mescaline nitrostyrene, however I do not know if it is more reactive. Have not worked with it.

Take a look here:

Or posted here (if starting from benzaldehyde):

My friend and I always cooked amphetamine in the forest.
That is, for synthesis we really only needed 3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons that show the reaction.

My role was always bring and serve, but we produced this product of 99.8% purity.
We had no competition in Moscow :/

we didn't use fucking acetone because it's bad for your health
