Methamphetamine Isomers Separation by Tartaric Acid

[Mr Good Cat]

@G.Patton general, is it not more simple to use d-tartaric acid CAS No. 147-71-7 but in much more less molar proportions around 1 (base):0.2-0.5 (d-tartaric)? Exact proportions might be estimated with a simple test.

 

[G.Patton]

Yes, you can use d-tartaric acid CAS No. 147-71-7, but it's more expensive and some people don't have an access to this. The example is shown with the cheapest and the simplest option.

True to that it does not produce crystals, can you help there to be the correct tartarat, or maybe the formula of the substance

 

[Bmth]

Bis Can you give me instructions about the procedure, or a link to the procedure? Thank you very much.
