Methamphetamine synthesis from Ephedrine or Pseudoephedrine

[RWG13]

Hi, thanks for guide.
Its possible to use white spirit instead of toluene?

Any non-polar solvent will work. Depending on whether it is heavier or lighter than water will tell you whether it will be above or below the Aquias layer of your solution when combined. You want to make sure you are extracting the right layer!

Sorry, I meant to say, "ANY non-polar solvent that doesn't mix well with water will work. I'm not sure what you mean by white spirit, do you mean like "white gas" or Coleman camp fuel, then the answer is yes. Not the best solvent as you want to try to pick one which leaves the least residue, but it will definitely work.

honestly a waste of the poor poor phosphorus just use HI made from phosphoric acid and NaI . ive got one question tho wouldent aluminum work as a phosphorus substitute since it would generate AlI3 insitu witch then reakts with water to form HI
2Al+3I2> 2AlI3; 2AlI3 +3H2O> Al2O3+6HI: . someone should look into it im kinda curius if it works if yes it would be a major upgrade and acessability and cost. u may need to change up the procedure slightly tho.
also as a slight proof of concept ima try to make some methyl iodide with it as a substitute im deffo not makin meth lol

Why wash sodium sulfate in Figure 17

 

[ZMI_AA0B]

Calcined sodium sulfate refers to

May I ask if there is still no white sediment when I introduce hydrogen chloride? What is the problem? Thank you

If you've done everything right up until this point, my first guess is that you have moisture in your nonpolar solvent that needs to be removed before protonation. Any moisture present will dissolve your hcl

Thank you very much for your guidance, teacher

Toluene, I sealed it with anhydrous sodium sulfate and dried it for more than 12 hours. Why is there still water

 

[CCL4 huffer]

sodium sulfate only dries it to a degree also if it was pretty wet before u need quite a lot id just predry it with sulfate destill it out and then further dry it with sodium and when u need it just destill it .
im guessing ur doin a gringard tho since i doubt ud need it that anh for most other cases .

Teacher, may I ask if there is no white sediment when I introduce hydrogen chloride? Do you know what the reason is

Isn't this too little iodine? I've seen other recipes usually use 2g of iodine per 1g of ephedrine.
