Metamfetaminsyntese fra efedrin ved hjælp af I2 og H3PO2

[hacke8]

Mine herrer, jeg lavede dette eksperiment, og jeg opvarmede det til 125 grader, fordi fosforsyre opvarmes til 130 grader, vil der være fosfatbrintgas (giftig). Er der nogen måde at undgå dette på?

 

[GhostChemist]

du kan bruge absorptionen af PH3 med NaClO og NaOH
H3PO2 ødelægges ved 170 C

 

[CARLITOBRO]

kan jeg bruge hydriodic acid 57% i stedet for hypophosphorus acid? venligst gentag

 

[caydiantak]

Fungerer dette med pseudo?

 

[Toti]

Hej, er der nogen forskel, hvis jeg bruger sudoephedrin i denne opskrift?
Tak skal du have

 

[Throw-off]

Forskellige forhold for efedrin og 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.

Hej, jeg har et spørgsmål: Kan man bruge kaliumjod i stedet for jod? Fordi kaliumjod er meget lettere at købe.

 

[G.Patton]

Hallo, nej. Disse stoffer har forskellige kemiske egenskaber.

 

[Throw-off]

Du kan bruge pottasiumjod til at lave jod. Det kan gøres på en doven søndag eftermiddag.

 

[CARLITOBRO]

kan jeg bruge hydriodic acid 57% i stedet for hypophosphorus acid? venligst gentag

 

[G.Patton]

Hej, nej, du kan hverken bruge hydroiodic acid eller phosphorous acid

 

[Bmth]

Spørg eksperter om svar, for jeg har fejlet og brugt en masse penge og materialer.

Your photo has a very high distillation temperature for dcm

 

[Pinkbay]

Lærer, kan jeg bruge DCM i stedet uden destillation og gå direkte ind i den overvægtige hydrogenchlorid?

 

[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...
