What is the easy, fast and guaranteed way to get rid of the odor of P2np after synthesis After completion, my washing method is to put the product from Amphetamine in a cup and acetone poured over it until it covered the amphetamine and stirred for about 15 times twice and put in a vacuum bag Is that right?

cyb3r0The reaction does not pass to the end, there should not be such a smell. What is the color of the product before washing?

Are you precipitating with water? The sulphate form is water soluble.From what I understand an anhydrous or nearly anhydrous solvent should be used.
How are your yields?

I don't think you understand. in sulfuric acid 37% pure there is 63% water in it .
I use the 96 % pure and there is only 4% water in it .
but you can use it this strong becouse it burnt when you add it this pure

I use it also with A-oil but never pure I did for 100ml oil 10 gr 96% and 17gr water it is still much better than the 37% you find everyware

And you are using 17gr water to dilute the sulfuric acid to provide burning?
That would be quite strange, normally you salt out in a solvent and dilute the acid with the solvent.

Pennywisejust before I need it I mix 17 gr water with 10 gr sulfuric acid 96% and add it verry slowly to my mix off 135ml methanol with 100ml A-oil
I use ice water for cooling .

I have explane it in post #349
Sauland that is nonesense in my opinion, dillute your acid with methanol if you use it for the oil too. You loose over 17g sulfat with the water. And also i would use a higher amount of solvent for the acid because it is easier to hit the pH 6 point then.

Then why add methanol? It will bind your water, and you will not get a water layer. You will get something like a gel that is difficult to separate or filter out. Usually, when acidifying the free base of amphetamine, the dryest ingredients are used to avoid problems with precipitation.
Or you need to do without alcohol so that the salt goes into the aqueous phase and then evaporate the water to obtain salt. By the way, in the case of hydrochloride, this option will not work, only with sulfate.

Can I use 85% phosphorus acid instead of sulfuric acid?

What’s the difference?
Saymynamehsb
that's the question :p
(i have never try phosphate)
information i have read.. officially it's the same...
i have ear phosphate better for IV ? i can't confirm... and best yielding with sulfate ... (but what about purity ?)
and for effect... officially the same but some prefer one, an others no :p

Phosphate is somewhat more soluble in water. That's about it. No other interesting differences.
