because it needs to keep the pH 13. after extraction with ether it drops to 9. how to pick them up then?

What is the cost of producing a kilogram of finished ice?.... Using this method of course.
Conclusion to my little experiment.
Don't do it
The color of your finished reaction looks like some p2np hadn't been reacted fully
So what did you get out of it?
That may be true, 1 1/2h into the process, the reaction kind of stopped and the temperature only decreased.
Once I poured the CuCl2 into the mix it only changed color, and it was a b*tch to keep the temperature at 80C in the end but I managed.
I started the crystalization with the sulfuric acid, but the problem was that the pH sticks kept the same color as the amphetamine oil, dark orange, didnt matter how much I poured inside, so in the end I gave up and discharged of it all.
It is not worth all of the hastle just to save up on some IPA and NaBH4.

Have you checked boiling temperature of your "amphetamine base"? It looks like not amphetamine oil. Have you got any sediment after H2SO4 solution addition?
Thanks for the update, may I ask you what is your flask size? 5L?
What is your yield of dry sulphate from your previous 200g p2np reactions?
I don't use any H2SO4 in my processes, I go amphetamineoil > filtration > crystalization > vacuum.
Hmm, you told that you add sulfuric acid and don't use H2SO4 I'm a little bit confused. You also can steam distill amph free base to get pure oil.
I use a 10L flat bottom florence flask, I works perfectly with my reaction scale.
My yield so far has been 90% and I'm very happy with this.
hello somebody did some reaction to methanol? I did on ethanol and now I have quite a lot of pure methanol and I wonder if the reaction will be successful too ...
Thanks for answer, do you use condenser on top of reaction? You take it off when you add p2np portion wise?
And what is your temperature when you add cucl2 to reaction? Do you heat reaction after the p2np addition is finished and then add cucl2
or when the p2np addition is finished you just add cucl2 and then heat the reaction to boil for half hour?
Please explain your process a bit as I am interested to know how you achieve such high yield
To be honest with you, I just follow the "recipe" to a T and use graded equipement.
If you do just as it is written you'll make the same progress.
What cooling system do you use for your 10L flask?
Hard question to answer, since I built my own cooling system.
