Title: Isomerically Pure Amphetamine Sulfate
Post by: asderjag1234 on August 06, 2013, 03:34 am
This guy on Atlantis is selling pure R-Isomer speed. If anybody could source here that would be awesome.

Don't you mean D-Isomer?  As far as I know, Dextroamphetamine is the most potent isomer.  It is available as a time-released encapsulated form.  I would rather do D-Amp.HCl, because sulphates are metabolized more slowly, if you had D-Amp.HCl, and you did a line, you would get a meth-like rush.   You don't get that from snorting or even injecting D-Amp.SO4

Well D and R both mean the same thing, they are both the Right Hand isomer. I didn't know that about the different kinds of salts, but I have never heard of amphetamine HCL.. I would like to try it. S-Amphetamine adds to the twitchy jitteriness for me

The D(aka l-amphetamine, (S)-amphetamine, or  (−)-amphetamine) is, in fact, the inactive isomer of Amphetamine in regards to CNS stimulation.(i.e. getting high)
Remember, D = l, L = d.  The problem with outdated terminology such as this, is that it gets incredibly ambiguous when something as simple as capitalization refers to a chirally opposite substance.

Additionally, if you tried to do a line of d-amphetamine HCl, you would get a runny nose and a lot of wasted product.  The reason why amphetamine is dispensed as a sulfate salt is because the HCl is incredibly hygroscopic, to the point where multiple recrystallization have always left me with a gooey mess and a fuckload of frustration.  It 'is' possible to get a dry HCl salt, but it requires solvents far more anhydrous than most drying agents will make them.



@asderjag1234:  If you want to separate the stereoisomers, simply convert to freebase then add half equimolar amounts of d-tartaric acid.  The resulting amphetamine tartrate salt will be chirally pure.

We were looking to isolate the d-l
A higher % in speed of d-amph or real pure d-amph would be awesome.
Would also be worth more than the overpriced meth.

But it sounds easy, but is practically impossible even with d-tartaric..

Good luck

Not sure what you mean here, are you trying to say that you are looking to separate the "d" from the "l"? Or that you are trying to isolate dl-amphetamine from other adulterants?

A tad more complicated than chiral separation, however:
Code: [Select]
N-Methyl-amphetamines were prepared by the reaction of the corresponding amphetamine with formaldehyde and reduction in the absence of acid. Thus, a mixture of 1 mole amphetamine freebase (136g) and 1 mole aqueous formaldehyde (81ml 37% or 75ml 40%) in 350 ml alcohol and an excess of aluminum amalgam was reduced for several hours, water added, aluminum hydroxide filtered off, the solution acidified and evaporated, and the freebase separated by means of alkali yielding phenyl-N-methylisopropylamine, converted to the hydrochloride, mp 140°C. Similarly, 70g d-amphetamine in alcohol with aluminum and 1 mole formaldehyde gave d-methamphetamine, which was converted to the phosphate salt. 1-Phenyl-2-aminopropanol similarly yielded ephedrine.
But it sounds easy, but is practically impossible even with d-tartaric..

Good luck

I've always found the procedure exceptionally easy and straightfoward.  I'm not sure what you are doing that would possibly add to the difficulty, but I can assure you it is well within the ability of anyone who is willing to make a serious attempt.

Yes I meant isolating the d from the l. Conversion of l into d would be awesome, but probably a wet dream...

Getting rid of addulterants is not so hard. Acetone for caffeine and lactose.. Then chlorophorm for...? And ethanol for??

But this is logical right:
Wash 1 gram of regular speed, then have 500gram left of dl-amph. Then add dexies with 25mg d-amph and wash again, will result in dl-amphetamine sulphate with 275mg d-a and 250 l-d

"Wash 1 gram of regular speed, then have 500gram left of dl-amph. "

I would love to know what you use to wash your amph... :D

In theories you can read  all about cleaning up amph paste or cocaine but in practice all these instructions are bullshit. it is a bitch to clean up amphetamine if you did not just arrive from a synthesis. Basifying and distilling it as much more successfull because the cunts cutting the material all the way from the big labs insert too many materials you will not get rid of by just washing it with ANY solvent system. Also, the instruction of leJunk to clean up cocaine is proper bullshit. take it from someone who knows what he is talking about. If you want pure materials you always have to distill or sublime materials in vacuum after basifying them. Very little success can be attained from the proposals I read so far.

Ahh, to save from future confusion, may I suggest using the term "chiral separation" or some variation, that way we know you specifically mean isolating a specific stereoisomer.

As uhrwerk pointed out, it'd be much better/easier to just basify and distill off the freebase.  Steam distillation works great for this IIRC.  I've used the milk steamer from a home coffee machine unit in steam distillations of related compounds, not specifically with amph though.

Yes, just like a 40mg adderall capsule contains 30mg d-amph, 10mg l-amph


@uhrwerk: You wont hear me arguing in leJunk's defense, the dude is a twat.
I don't think sublimination/vacuum distillation is the only option for those wanting to get fairly clean amph, as I said previously, steam distilling is meant to be the bomb for amph, and some slightly modified home brew equipment is the only requirement.  I.E. within the reach of the average joe.

Yea, don't really care about the terminology, I just want pure amphetamine sulfate of just the right hand isomer. Or I would like if somebody could get their hands on some of Walter White's stuff ;)

Is this any different then what capsule corp is selling? I'm interested.

Why are pre-made amphetamine capsules so damn expensive? I can buy $80 worth of amphetamine sulfate and make 50 capsules, turn around and sell them for $12 each. As far as I can tell, his are just regular amphetamine sulfate, so 50/50 Left/Right hand isomers
