Síntese de metanfetamina a partir de efedrina usando I2 e H3PO2

[hacke8]

Senhores, fiz esta experiência e aqueci a 125 graus, porque se o ácido fosfórico for aquecido a 130 graus, haverá gás fosfato de hidrogénio (tóxico). Há alguma forma de o evitar?

 

[GhostChemist]

é possível utilizar a absorção de PH3 com NaClO e NaOH
H3PO2 destruído a 170 C

 

[CARLITOBRO]

posso usar ácido hidríodico a 57% em vez de ácido hipofosfórico? por favor, reproduzir

 

[caydiantak]

isto funciona com pseudo?

 

[Toti]

O que é que eu posso fazer?
Obrigado pela ajuda

 

[Throw-off]

Diferentes rácios para efedrina e pseudo.

 

[amieri]

You want a molar equivalent , these are hypothetical amounts, but say the the 6g of ephedrine is 20mmol of one mol of ephedrine then you'd want 20mmol equivalent of pseudo.im by no mean a pro and have never even looked up the molecular weight of either of them put that's the idea .
There's a post on here somewhere I believe from patten that is very detailed and informative about the subject definitely look it up because this is something that is very important in all reactions.
Sincerely B

Olá, tenho uma pergunta: em vez de iodo, pode usar-se iodo potássico? Porque o iodo potássico compra-se muito mais facilmente.

 

[G.Patton]

Olá, não. Estas substâncias têm propriedades químicas diferentes.

 

[Throw-off]

Pode utilizar o iodo potássico para produzir iodo. Pode ser feito numa tarde preguiçosa de domingo.

 

[waltjr5858]

It can be done in about 20 minutes

[G.Patton]

Olá, não, não se pode usar ácido iodídrico, nem ácido fosfórico

A tradução deve refletir com precisão a terminologia técnica e as nuances associadas às ciências químicas.

Your photo has a very high distillation temperature for dcm

 

[Pinkbay]

Professor, posso usar DCM sem destilação e passar diretamente para o cloreto de hidrogénio com excesso de peso?

 

[William Dampier]

You can do this, but it is better to extract into the water layer when acidification and evaporate part of the water. You can use aq. HCl

 

[Saâd]

Hello, please can you give the weights that can be followed with the steps to get one kilogram ?

 

[William Dampier]

You must control the boiling to avoid problems with the volcano. Use boiling chips. Change the weight you need according to the specified proportions.

Hello, I have a question
I got a good result through this work
I have a few questions
1. It was heated to 100 degrees in hypophosphoric acid + ephedrine + iodine
There was a weight loss for the result. Would 110 degrees be okay?
2. Is it okay to calculate the capacity twice or three times for the mass production process and run the process? If so, how should we calculate the temperature and time of the reflux cooler?
3. I'm most curious about the process for number two. Simply put, if you start with six grams of ephedrine, if you put two or three times the dose in every process and manufacture it
I wonder what the temperature and time of the reflux cooler should be
4. The process of reflux cooler refers to the process in hypophosphoric acid + ephedrine + iodine

 

[GhostChemist]

The temperature can be 110 but longer in time
In this synthesis, phosphine is formed, therefore, an increase in the volume without ventilation hood is unsafe

 

[cicici]

Thank you for your answer
1. If you increase the volume, how much volume is appropriate?
2. If you increase the volume, how should you determine the time and temperature?
3. Why does it take longer than 100 degrees if you proceed to 110 degrees?
4.What is the appropriate temperature in your opinion?

 

[kafka82]

I am newbie - is there a video of this detailing the process? Also particualrly concerned about the best type equipment to procure fo rmagnetic heater and the reflux for example...

https://erowid.org/archive/rhodium/worlock/meth.htmlI followed the recipe from here but failed what is the mistake where is the expert who can explain

 

[@speedboysss]

https://erowid.org/archive/rhodium/worlock/meth.htmlI made crystal meth with the Erwoid recipe but it failed. All the procedures were done correctly. What went wrong? Please correct me, where are the experts?

Kde je problém? poradim pokud budu znát odpověd. Klidně napis SZ
