best purification method for my rolls?

[Drock]

what would be the most effective purification method for rolls that like tested 90% amphetamine and 10% MDxx. I believe there amphetamine though not meth, meth makes me sicker than these did.
marquis: changed to brown slowly
mandelin: changed green instantly with purple spots
meck: changed brown/purple ish
I know an anhydrous acetone wash would leave me with MDxx or meth, but would amphetamine remain insoluble in the acetone as well?
Or would I be better off dissolving the MDxx in a cold water wash, and washing away the adulterants that are insoluble in water?

thanks all

the polar nonpolar method generally gets rid of impurities but i have no idea what solvent to use.. i know amphetamines a readily soluble in water though, dont know about mdxx

There's no easy way to get the amphetamine and MDMA separated (unless you have a vacuum distillation apparatus). There was a thread about this a little while ago.

After a bit more searching I found an extraction tek that recommends an anhydrous acetone wash to remove fillers/binders, leaving MDxx (and in my case amphetamine). Then washing the remainder with 99% isopropanol alcohol, dissolving the amphetamine and leaving MDxx behind.

Amphetamine is insoluble in isopropanol (so don't go taking 120mg of your extract!). Like I was saying, the easiest way is to fraction the freebases.

Then washing the remainder with 99% isopropanol alcohol, dissolving the amphetamine and leaving MDxx behind.

did you just infer that part? if not, you should contact the host of the tek and tell them to take it down. it's a good thing nuke spoke up!

It'd be kind of a weird lapse of logic for someone to put in a tek and have no one correct it up to now... Why would a fairly polar solvent not dissolve the more polar MDMA but solvate the less polar amphetamine?
