Sintesi della metamfetamina dall'efedrina mediante I2 e H3PO2

[hacke8]

Signori, ho fatto questo esperimento e l'ho riscaldato a 125 gradi, perché se l'acido fosforico viene riscaldato a 130 gradi, si forma il gas idrogeno fosfato (tossico). C'è un modo per evitarli?

 

[GhostChemist]

si può usare l'assorbimento di PH3 con NaClO e NaOH
H3PO2 distrutto a 170 C

 

[CARLITOBRO]

posso usare l'acido idriodico 57% al posto dell'acido ipofosforico? per favore, replicate

 

[caydiantak]

funziona con pseudo?

 

[Toti]

Salve, c'è qualche differenza se uso la sudoefedrina in questa ricetta?
Grazie

 

[Throw-off]

Rapporti diversi per 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

Salve, ho una domanda: al posto dello iodio si potrebbe usare lo iodio di potassio? Perché l'idodio di potassio si acquista molto più facilmente.

 

[G.Patton]

Salve, no. Queste sostanze hanno proprietà chimiche diverse.

 

[Throw-off]

È possibile utilizzare lo iodio di potassio per produrre iodio. Si può fare in una pigra domenica pomeriggio.

It can be done in about 20 minutes

[G.Patton]

Salve, no, non si può usare né l'acido idroiodico né l'acido fosforoso.

Chiedete agli esperti le risposte perché io ho fallito e ho speso molti soldi e materiali.

Your photo has a very high distillation temperature for dcm

 

[Pinkbay]

Professore, posso usare il DCM senza distillazione e passare direttamente al cloruro di idrogeno in sovrappeso?

 

[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?
