Methamphetamine from ephedrine tablets

[G.Patton]

Aspirin 10 g/100 ml ethyl ether
Caffeine 0.2 g/100 ml ethyl ether
Ephedrine insoluble in ether
Use anhydrous ether!

 

[Joeking]

Hi legend, I can't for the life of me figure out how to seperate the ephedrine from the caffeine as they are both insoluble in ethyl ether, do you have any idea, TIA.

Sorry and please help
I have finished following this video, and I will not produce Methaoethamine crude powder, please help I do not understand what is the next step for me to be able to produce Methamphetamine crystals (ice/meth)

Hello, yes, it is

Hii , Patron i have trouble when exracting 200 tablet contains 26g Theophyline & 2.5 g Ephedrine HCL, finally i got less crystal when bubbling hcl gas.
I want a consultation, Thank u Master.

what i do is
1. add tablet powder to toluene solvent, stir 20min and evaporate.
2. add 2 gram NaOH solution to powder with 96% Isopropyle Alcohol Solvent to powder and evaporate.
3. add powder to beaker. add 4gram NaOH solution, until heatdown than add Petroleum Ether 90-120° C, stir with magnetic stir.
4. add solvent to coffe filter
5. the solvent Bubble with HCL Gas, to grow crystal grow. finally get 0.4 Grams. Whats Wrong? i think i must get 1.6+ Grams while correct step in my literation in bbgate

Other Question :
1. do I not need to dissolve theophylline with toluene, because it will remove ephedrine hcl?

2. Petroleum Ether best Celcius for good extraction from Ephedrine HCL tablet contains Ephedrine HCL & Theophylline.

a. Petroleum Ether 30-60° Celcius
b. 40-60° C
c. 80-100° C
d. 90-120°C

3. does petroleum ether dissolve theophylline too?
4. How Much NaOH add by water for 200 tablet contains 26g Theophyline & 2.5 g Ephedrine HCL
5. In fester video, He's use 96% Isopropyle Alcohol solvent while making NaOH Solution in ephedrine hcl srystal step. Whats the diffrent using water & Isopropyle alcohol ?

how to choose Hydrocloride Acid 35% while the information is:

1. HCl 0.05 Molarity 1000 ml
2. HCl 0.5 M 100 ml
3. HCl 0.1 M 100 ml
4. H C L Merck 100ml
5. HCl PA 10 ml

how to choose H2So4 35% (Sulfuric Acid) while the information is:
1. H2So4 AR
2. H2 So4 0.1 Molarity 100 ml

Hello, @robertlouis. Where have you read about evaporation solvent after Ephedrine dissolving? Also, there is detached topic about extraction: https://bbgate.com/threads/ephedrine-extraction-from-pills-methods.2443/ Please read this carefully.
https://en.wikipedia.org/wiki/Molar_concentration Learn about it here
1M HCl solution has HCl 35.5% concentration
0.35 M H2SO4 is ~35% H2SO4 solution

Thanks Patron, u very kind to me.

Did anyone tried the alphastoff v4 tutorial? (Is in German)

The PSE extraction is very different too the methods here disgust

 

[m03]

anyone know vendors that stock pseudoephedrine / brand or websites that sell ephedrine containing pills?

 

[J-man]

Hello, just wondering how big could you scale these 2 methods up to? Thanks

 

[German Chemist]

Can I also use BoxaGrippal, which are very popular in Austria. Ingredients below:

• 200 mg Ibuprofen
• 30 mg Pseudoephedrin hydrochlorid

 

[G.Patton]

Your question has already been discussed there https://bbgate.com/threads/ephedrine-extraction-from-pills-methods.2443/post-8578

 

[J-man]

Hey sorry to ask here but how big could you scale the moscow and/or Hypophosphorous routes up to?

 

[G.Patton]

I think yes but not too much.

 

[J-man]

As in how much would you say? 1-5kg 5-10kg or 10-50kg final product batches etc?

 

[G.Patton]

There is low yield and these ways don't gain commercially benefits. It is better to use p2p precursor in order to scale reaction up.

 

[J-man]

thanks

Why is sodium thiosulfate added when processing the mixture? Is it okay to use sodium hydroxide directly? I don't quite understand what the role of sodium thiosulfate is.

 

[diogenes]

It`s to capture any remaining Iodine.

 

[Re186]

The hypophosphorous acid method produces a lot of white powder in the condenser tube during reflux, and the condenser tube is completely blocked after about one hour. Is it normal?​

G.Patton​

​

 

[Re186]

I guess there are two possibilities, one is that the white powder is desublimed phosphorous acid, and the other is that there is something wrong with ephedrine hydrochloride and it is a fake

I call his pseudo if fake
