I might be wrong but the smell and taste associated with street amphetamines comes from the leftover freebase.I suspect they leave it on purpose to “flavor” the fillers.

All methods posted here yield relativley clean amphetamine freebase, which you (hopefully) further purify by steam distillation(before precipitation ofcourse) and or acetone wash after precipitation.Question dosen’t really make sense.Amphetamine is amphetamine, either l or d, there is no “apaan...

i found this... you think is ok ? That’s the stuff, yeah.Very good solvent.

Al/Hg amalgam reaction yields racemate

I agree, needs more drying + acetone wash, i bet it’s gonna come off cloudy.

I don’t know if you are aware but gallium forms amalgams with metals, including Al.Everything you said about Hg in the first paragraph can be applied to gallium.Please correct me if I’m wrong, anyone. I read about liah, I don’t wanna work with it at the moment, too dangerous in my setting, And...

I’m gonna give it a try and report back if I can find some.

Do you know for sure gallium does not work? I was looking to explore less toxic materials.

A bit unrelated but does anybody know if galium salts form amalgams, if so which? Or do i need elemental galium?

Well, I would think in general a reaction that runs to the end at a constant say 60 C, compared to a reaction that quickly goes to 80 C, then is cooled, heated again etc will have a better yield.Just my thinking, maybe somebody can correct me.Have you tried straining on a loose mesh and not...

Look for a supplier from poland, least restrictive in the EU

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?

No, mixture was used at room temp with only a little agitation of the container beforehand.I will do this next time and report back.I will also source some fresh conc. orthophosphoric acid to compare.Thanks mr patton.

Reaction is more violent with just water? Or no difference?

Tell us what you’re missing or where you have trouble understanding.

I don’t know what he uses but 96% is fine, just be careful when adding it to solvent, it splashes on contact.

Appropriate plastic barrel, cooling by barrel-in-barrel.Condenser with a pipe inside a bigger pipe, the outer section insulated from the system with silicone or something else appropriate, fitted with water in and water out, really easy. Or batch reacor if budget allows, mister Patton has a...

Coincidence has it I tried h3po4 yesyerday.I had 50ml H3PO4 in which 2 additional gram of it’s anhydryde were dissolved.I drove reaction to the end, extracted ipoh with xylene, dried over anhydrous mgso4 for 10-15 minutes.The somewhat dry xylene with freebase was transfered to a clean dry...

At 30g rno2 and paper thin cut foil is a surefire recipe for overflow hehe.When I go over 5g of substrate i ball up my alu by hand, making not too loose not too tight balls.Helps keep the reaction under control, may need some heat to drive it to the end, but not all the time.

Hotplate, heating mantle(might be too much even on low), deffo not open flame.
