As I said before, I have not tried this method yet, but it was copied from another forum (I think from the Hydra forum). The method may require some details that experts may assist with. Such as activating zinc with hydrochloric acid before using it. There are also some unique synthesis, such...

Sodium sulfate anhydrous. Na2SO4

ether

Yes, add until you reach pH 11-12

Yes, Ethyl acetate is used to extract oxime from the mixture

Is drying the citric acid (in IPA) with sodium sulfate sufficient, or must it be dried with heat?

I read a method talking about this, but I have not tried it I said that reduce phenyl-2-nitropropene to phenyl-2-nitropropane Then from phenyl-2-nitropropane to methamphetamine with n-methylformamide + Zn + HCl Yield = 5g meth from 5g P2NP

I read a post by someone who synthesized l-ephedrine by refluxing l-PAC with methylformamide, and the yield was about 21g l-ephedrine from 20g l-PAC I'm not sure if this method will work or not.

I searched for a while about the difference between amphetamine salts in terms of pharmaceutical properties, but I did not find any useful information. If you have any information or references, please send them to me Thanks in advance

There are more than these 3 salts (saccharate, aspartate, oxalate...) I think each salt has different effects, so I decided to try citrate, but I couldn't find any information about it. But I found a patent that says: mono amphetamine phosphate is more effective, dose for dose, than is the...

I decided to try amphetamine citrate. I dissolved citric acid in IPA and added it to the amphetamine base, but not much salt was formed, only a little salt precipitated and it looked sticky. (ph = 6). What do you think the problem is? The citric acid I used is a monohydrate.

You can use a non-polar solvent (ether, benzene, toluene)

I don't understand your problem I think there is no difference. The pH of the mixture must be 11-12. The DCM layer is the bottom layer. I think it is better to evaporate the DCM and then add acetone to the amphetamine base. Why do you still have the ethyl acetate and oxime solution?!! Yes...

Until it cools to room temperature

Yes

Captagon tablet contain 50 mg of Fenethylline But it no longer exists.All existing tablets contain amphetamine and some adulterants.

The method was copied from the Internet. I plan to do it in the near future. I'll let you know when I do it.

I think yes

Until all the tin chloride is dissolved

Compared to the reduction of P2NP on aluminum amalgam, this method offers a significantly quieter reaction (The reaction isn't exothermic ), better yield (90%) and a very pure substance (no additional purification required). Dissolve 15 g of P2N0 in 50 ml of anhydrous acetone Place 100 ml...
