L-Ephedrine.Hcl is a lot less soluble in alcohol than Pseudoephedrine.Hcl.

Im petty sure i have l-eph in my pills.

(The pills are european and not super gaked, total pillmass is about 60g and shold contain 30g e.hcl)

What solvent would be best for extraction?

Latest advice is to soak in IPA for 24-48 hrs.
Any other suggestions?

Yes, ephedrine.HCl is less soluble in alcohol than pseudoephedrine.

Nevertheless any anhydrous alcohol will work just fine for extraction, hot alcohol will work better than cold alcohol and extracting by using several single portions of alcohol works better than using a large amount of alcohol for once.

Hot IPA is fine - cold IPA is not good as the solubility differs very much from cold to hot. You may soak it as long as you want but heat it up before filtering and do three hot extractions - more is nonsense, less a waste.

What amount of alc do you recommend?
Bees say just cover it about an inch or so...

But that really depends on the container beeing wide or narrow...

I used 20 ml for 6g pill massmass (3g e.hcl @ 100% return).

Is this too much or to little?

[Organikum]

Too little.
Use 3 times 50ml waterfree HOT IPA.
The 3 times is more important than the amount, got this?

[jammin]

I got it all!

I'll give it a shot tonight.

Thanks you, you wonerful personality!

Join the three 50ml extracts and before evapourating the IPA, add three drops (yes drops, one per theoretical gram ephedrine) of HCl (20% or 30% doesnt matter).

This guarantees acidic conditions and the ephedrine in form of a non-volantile salt.
(applies only for ephedrine not for pseudo)
