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

[TucoSalamanca.]

my calculation on the p2np nabh4 amphetamine method
IPA 40-50 ml
H2O 12,5 ml
NaBH4 3.5 g
P2NP 2 g
CuCl2 +-0.2 g 9.675 H2o
NaOH (25% water solution) 16 ml
Acetone (dry) 5-10 ml
I first put ipa and h2o and mix for 2 minutes, then I add p2np, then I dissolve 0.200mg copper chloride in 5ml water and add it, but the temperature does not increase.

How many ml of copper chloride 200mg will I dissolve in water and add 1ml? First I add ipa and water, then I add nabh4, then I add p2np so that it does not exceed 60 degrees, the temperature increases, but when I add copper chloride 200mg, the temperature does not increase, I dissolve it in 5ml water and add it, I make a reaction with a 2lt 3-neck glass balloon.

The first time I tried this reaction it worked perfectly fine. Using the same everything and re crystallizing p2np so it was fresh it keeps failing no matter what I do. I keep sending up with a very very pure white powder that is not the same as the first time. It almost has a slightly fruity smell to it and right before you add sulfuric acid the time it worked the liquid was a golden color and every time after it's very clear. I think I am doing something wrong with the addition of the p2np in the first steps. Is there a maximum time that it cannot sit reducing? I know the video says it should take around 6 hours to add all the p2np so I am assuming it is safe up till that point. I do know the first time I did it when I was adding the last bit of p2np it stopped reacting to adding the p2np right about that time whereas every other time after that it is still slightly reacting exothermically and bubbling. I'm not sure what could be the difference between the first time and every other time. Maybe someone has some tricks or has had it failed in the manner I have. Thanks

Can the alcohol be used again after it has evaporated? Or has it formed an acetropic mixture (88%ipa/12%h2o) due to the last use in the reactions?

SashinskiYou could try... it would have to be distilled for sure since it has a color to it. Something is in there.... I am having a little trouble with mine and I'm hoping someone sees these post and knows what's going on. First time I made it perfect.... nice light tan... strong effects. Next time and every other time the final sulfate to be filtered is very white with a fruity smell ? It almost has a slight pink huhe to it. Very weak effects. I'm assuming it's over or under reduced? Anyone know which one? Or what would cause it? Too long or not long enough? Temperature....which was kept in line? I mean reading the patent they put all the p2np in like 10 minutes and roast it with the copper for 20 minutes saying reduced yields past 30 minutes. It looks like it fool proof but it's not... so over or under reduced so I can fix this thing.... thanks anyone
