I was wondering if any one knew what isomer (d or l) is the ephedrine you buy over the counter (like Texaco, or whatever)? Also, using this synthesis, what by-products (other than water) need to be removed? F. Y.I. I am using the synthesis that involes ephedrine, thionyl chloride, and LiAlH4

How bout I trade you gram for gram Red phosphorus (reusable) for your LAH. Your ephedrine is laevo-ephedrine from natural sources.

Not to many impurities with this method. Really no way to tell what they are without some expensive tests. One could geuss, but really it doesn't mater. A/B extraction acetone wash, re Xtlization it's all good.

So, using OTC ephedrine should, in theory, work then? I just don't want to waste what precious few amounts of chemicals I have.

This method is rarely used in the 'black-market' no?

Yes it will work in "theory" just please don't waste that LAH and thionyl chloride. I'm begging you. At the very least e-mail me and we can talk. There are ways of making HI acid without redp.

Your biggest problem will be cleaning said ephedrine.

Using LAH and thionyl chloride to make meth.... What will they think of next.
