Sinteza metamfetamina iz efedrina z uporabo I2 in H3PO2

[hacke8]

Gospodje, naredil sem ta poskus in ga segrel na 125 stopinj, ker se fosforjeva kislina segreje na 130 stopinj, nastane fosfatni vodikov plin (strupen). Ali obstaja kakšen način, da se temu izognemo?

 

[GhostChemist]

lahko uporabite absorpcijo PH3 z NaClO in NaOH
H3PO2 se uniči pri 170 C

 

[CARLITOBRO]

ali lahko namesto hipofosforne kisline uporabim 57-odstotno hidriodno kislino ?

 

[caydiantak]

ali to deluje s psevdo?

 

[Toti]

Pozdravljeni, ali je kakšna razlika, če v tem receptu uporabim sudoefedrin ?
Hvala.

 

[Throw-off]

Različna razmerja za efedrin in psevdo.

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

Pozdravljeni, imam vprašanje: ali bi lahko namesto joda uporabili kalijev jod? Ker je kalijev idodin veliko lažje kupiti.

 

[G.Patton]

Pozdravljeni, ne. Te snovi imajo različne kemijske lastnosti.

 

[Throw-off]

Za izdelavo joda lahko uporabite potasijev jod. To lahko storite v lenobnem nedeljskem popoldnevu.

 

[CARLITOBRO]

ali lahko namesto hipofosforne kisline uporabim 57-odstotno hidriodno kislino ?

 

[G.Patton]

Pozdravljeni, ne, ne morete uporabiti niti jodove niti fosforne kisline

Za odgovore se obrnite na strokovnjake, saj mi ni uspelo in sem porabil veliko denarja in materiala.

Your photo has a very high distillation temperature for dcm

 

[Pinkbay]

Učiteljica, ali lahko namesto tega uporabim DCM brez destilacije in preidem neposredno v preveliko količino vodikovega klorida?

 

[William D.]

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 D.]

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?

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...
