Best method to extract Eph from these pills (with pictures)

aaa · Sat Jun 04, 2005 6:22 pm

They are "white crosses" and (see image) are stated to contain 50mg ephedrine hcl. In theory, what would be the best method to extract the ephedrine from these pills?

Many thanks for all the help this community has provided

This is what the pills look like from the other side:

Can anyone else confirm that this is the best method to use for these pills? I imagine they would contain less crap than other pills, I think they're made in Turkey.

Many appreciations for your reply Lyral

5 deje reposar, separe la fase solida de la liquida
6 ponga la fase liquida a destilar, hasta que solo le quede un poco de liquido
7 coloque el residuo en un cristalizador
8 seque con aire caliente o a la intemperie
9 Ud. debera haber obtenido unos bellos cristales de HCl-PEphe

2 wash with acetone the dust, praises/pours off. Conserve the Dust
3 place their free acetone dust, in a suitable container and add ethanol
if it has absolute, he is better, alcohol of 100°
4 awhile shake by the mixture of dust and alcohol
5 let rest, separates the phase been accustomed to of eliminates it
6 put the phase eliminates to distill, until single it has left a little I eliminate

Is pure methanol OK?

Does it matter that the pills contain Ephedrine HCl and not Pseudoephedrine HCl?

El metodo, antes descrito, es un metodo totalmente empirico y funciona perfecto para ambas sales. ( Claro, en ese tipo de tabletas )
El alcohol, es Etanol, CH3-CH2-OH , el cual es mas sencillo de conseguir, si ud tiene acceso al Metanol absoluto, es mejor CH3-OH. El usar Alcoholes libres de agua, evita que en la separacion, se arrastren endulzantes.

Cita :Ephedrine Hydrochloride. C10H15ON·HCl
Prismatic needles, mp 216°C., [α]D22 -32.5°. Easily soluble in alcohol and water. Its aqueous solation is stable at boiling temperature.

What exactly does that mean: 6 put the phase eliminates to distill, until single it has left a little I eliminate

apologies if i have violated any taboos, could someone please define "posting sources" for me? I was under the impression a "source" was an entity which the substance was acquired from, not the actual substance itself!

In any event, my current understanding is that the best method to use for these specifically would be the method posted above, which seems to be similar to the Placebo cure i have been referencing https://www.synthetikal.com/Rhodiums_pdfs/chemistry/thecure.html , the main differences being the acetone/methanol phases reversed as well as the toluene/naoh/magnesium sulphate additions. Are these extra steps not necessary because these particular pills are relatively unadulterated? Also is the "Acid/Base" phase necessary or could one go straight to reaction after this? Any thoughts from my meso-american amigos?

aaa, even though you didnt explicitly post a source i would be careful putting pictures like that up because if the manufacturers or the dea sees that they may change the composition of the pill and your extraction technique may not work the next time you buy them.

i cant comment on the extraction techniques though since ive never done them. i have only a limited interest in the final product and the 3 times ive seen it synthesized unadulterated pseudo that was brought back from mexico was used. if i had to guess though id say do an a/b on it just for good measure since solvent washes might not get all the crap. dont forget to recrystalize. but like i said, im not an authority on the subject so take it for what its worth.

Hmmm the line is very fine here....

Sources should never be posted, half the fun is finding out your own source so enjoy! But i think the pictures above are (just barely) ok as it has been mentioned... everyone already knows cold and flu tablets contain pseudoephedrine, just dont mention where to buy one, two or 40,000 packets and your ok...

In future though as a personal habit dont post pictures of labels or brands its not good for the company its associated with.
