>O,O-Dibenzoyl-2R,3R-Tartaric Acid
I think it is much hard to find than d-tartaric acid

Sorry, I was confused. L(+) isomer can be used to get (-)D-amph/methamph. Procedure a little bit different from mine and you can get another isomer. I worked with D-Isomer only. You'll get D-amph L-tartaric acid as an precipitate.
So can we then take this tartrate salt D-Amph L-Tartaric, treat with sodium hydroxide, extract and precipitate with with sulphuric acid?

Acetic essence is often used to produce hydrogen, but I "start" the reaction to produce hydrogen with water. Less acidic medium, which means less alkali must be added later.
In this method is not used acetic acid, but is used another chemical together with p2np in a solution, is that the difference compared to the method used in the 2 videos to make amphetamine from aluminum amalgam?
Im talking about only the first part of the method, production of amphetamine, not about the second, Extraction of d-amphetamine.

Hello, almost the same. There is no acetic acid only.

can somebody explain me again pls what would be the difference if I use l-tartaric instead of d-tartaric acid with freebase? with l-tartaric there would precipate what? the d-amphetamine l-tartaric salt? What would I do then?

GAAAH! Use the right nomenclature with capital letters! Mixing them gets so damn confusing.

D-(-)- tartaric acid will give you a tartrate salt of D-meth/amph. I honestly don't know what the physical properties of that salt is, how well it stores, melts or tastes. But it should be fully usable.

LOL.
L-(+)-tartaric acid.
Sometimes called d-tartaric acid (with a LOWERCASE "d").

yeah that is the one i am talking about. did you use this one to make dextro-amp?

with L-(+)-tartaric acid it means you will have dextro amphetamine salt crystallizing or levo? sorry its very confusing.

"You can repeat procedure of cleaning precipitate of l-amphetamine d-tartaric salt by methanol to increase yield."

I want to do that. Can you describe the steps in more detail?

L-tartaric acid will salt out L-amphetamine. Simple as that.
Mix the tartrate with the racemic freebase and a salt will be created. Thats L-amphetamine tartrate. Filter that out, separate. Repeat a couple of times. Eventually you will have a freebase with mostly D-amphetamine in. Salt THAT out with sulphuric acid (or bubble with dry HCl gas if it's meth) to get your non-racemic product.

ok. but I want to check it with CAS numbers because I have still conflicting info what yields what salt.

- (the one that comes from fruits and is cheap and available) CAS 87-69-4, L (+) - tartaric acid -> results into ?

(unnatural one and is expensive) CAS 147-71-7, D (-) - tartaric acid -> results into ?

Question about p2np to amph.
So I used aluminium granules as I had that laying around.
After I amalgamated it which was deep grey sludge floating around I drained and wash 4 or 5 times added small amount of distilled water and dripped 14%p2np in ipa slowly at 1st but my exotherm wasn't bad 45°c'ish I speeded it up but even after all addition in about 15mins it never went over 55c without cooling, I don't think enough hydrogen was produced from the slow reaction. Could I bubble h2 through mixture from hydrogen generator to make sure I'm using enough hydrogen or have I just fucked it up with granules?
Just wanted to know before I basify

It is better to use Al foil from grocery store for this synthesis way. In case of H2 bubbling, it is better to use Pd/C as catalyst.

I've tried to look but can't really find an answer for pd/c preparation
I have activated carbon and maybe 50g of palladium chloride made by dissolving palladium in aqua rega and bubbling chlorine through which dropped out a nice dark red salt looks a little like iron oxide. And dried to constant weight.
How do I make pd/c
Sorry a bit off topic.
Is pd/c pyrophoric?
