Syntéza dextroamfetaminu (Nabenhauer, 1942)

[Chemdogkm]

The powder pulled from amalgun rxn looks to b 1.5g but on scale it says 10g? It smells like amphetamine ,but when applying flame to burn some as freebase like the video of amphetamine salts smoking it does not melt into oil,it does nothing or turns to black ash afrer heated for long time. Is that correct,Theamphetamine sulfate cant be smoked? Is it messed up product somehow? Or is it okay?

 

[G.Patton]

What amphetamine salt have you tried to smoke?

 

[Chemdogkm]

Tryin to apply inderect flame to amph sulfate

 

[G.Patton]

This salt isn't smokable.

 

[Chemdogkm]

Is naphtha usable to extract since it will mix with iisopropyl from the reaction that should be doable?

 

[G.Patton]

It's really hard to understand you.
Yes, you can use naphtha instead of PE.

 

[Chemdogkm]

Okay good to know. Thank u.Is there a way to change it from sulfate to sum other salt so that it is smokeable?

 

[G.Patton]

Yes, basify this amph salt and then extract (acid-base extraction). Acidify by an appropriate acid.

 

[Chemdogkm]

So alkaline to ph12 with lye,extract with naphtha, acetone and sulfuuric to ph3 and that should work fine?

I have tried the AL/HG a couple times with no success yet... typically the product separates from the sludge looking pink to red with no activity whatsoever. I'd like to try the dripping in idea but how are you keeping the aluminum from becoming non reactive as it sits there in air. I see you call to drop 30mls of water in but that won't cover the aluminum that is amalgamated and it doesn't take long for it to become unreactive. I have had this happen and the reaction just flat out stops. How are you keeping the reaction going?

 

[G.Patton]

That is typical result of overoxidation and overheating during acidification procedure.

You can don't wash your Al/Hg by water and carry out reaction directly there.

 

[waltjr5858]

So instead of washing out the salts just leave the aluminum underwater or at least just enough to cover them and start dropping in the p2np? Because reading your instructions on this one say to wash the amalgam and then put in 30 mL of water and then begin the dripping of p2np over the course of 50 minutes. I'm pretty sure 30 mL of water won't cover that much aluminum so how does it prevent from being oxidized or is it okay to have more water in there covering the aluminum fully Amalgamated and then drip in the p2np?
