    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    so I did. or could it be caused by too high pH of the amine .. I think it is too alkaline. you can hardly see the difference on the strips, but it seems to me that the pH is 13-14 the next time after the reaction is complete, I will want to lower the pH with acetic or hydrochloric acid and...

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    why the synthesized amphetamine has no power? everything done as it was written in the recipe. the smell is there, the taste is bitter, and the potency is very weak… what could it be?

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    in your opinion, after adding the base and the oil flows out, IPA is added and mixed and then the top layer is pulled off?

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    gentlemen, I still did not get a reply to point 7. for me, after removing the top layer and adding to the bottom (water) IPA NOTHING HAPPENS. two layers are not formed again

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    I wonder if it will not be better if in the end you will not add 50% acetic acid to get down from the pH lower and then add a little alkali to these 12… what do you think?

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    aaa and the question is what pH should be after the end of the reaction? mi shows 10-11. after adding alkali the base pops up and it is 12-13.

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    Ok, did I count well for 250g p2np that I would need 550g NaOh in 1650ml dh20? I found a dependence that the NaOh solution was added in the proportion of 44% to the amount of IPA + dh20

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    gentlemen, reading all this and doing it myself I got confused ... namely after adding cucl2 after a while two layers are formed for me, why? I form two layers before adding the alkali. when added, the oil seemed to mix with the top layer.

    One-pot Amphetamine Synthesis From P2NP With NaBH4/CuCl2 (1kg scale)

    after adding 25% NaOh solution, phase separation, I added 1/3 dcm of the volume of aqueous solution. my question at what temperature should I distill? in my opinion, apart from freebase, there is still water in this solution, IPA and dcm, am I right? then distillation at Ok 83 degrees?the...
