Confused
Hey folks, I'm trying to se if I understand this.
to extract psudo from pills, I powder them and soak
in solvent, filter and rince, and save the mudd.
this is then added to DH2o, which is then modified using
lye and hcl to make it basic, and then acidic to transfer the psudo to the water.
the water is then evaporated off leaving the psudo.
I'm betting this is close, but it raises a few q's
what exactly is the role of the solvent? I thought that the a/b was what extracted the
psudo. so why not just put the pills in the a/b? or is this what I got wrong.
I'm looking through all the synth info I can find and I find
2 different things. one is the a/b, which I think I got a grip
on, but the other only calls for a solvent soak, filter, rince and evaporate.
I got the fealing that I am combigning the 2.
help...........but please don't give me any of that "do some reading" or "go hear".
I have and Now I need some p2p advice.
thanx
P.s. What colour should the 12 be once dried?

Re: Confused
you crush the pills add solvent, wait till the mudd settles to the bottom, syphon the liquid, filter the liquid, boil the liquid, take what comes outta the boil, and repeat.

Re: Confused
and the role of the solvent is to remove that initial binders on the pills, after that step., the a/b removes the rest,

Re: Confused
read this thing, just the part about extracting the ephi..
its what i did, works pretty good, http://www.rhodium.ws/crystalcreations/pushpull.html

Re: Confused
your solvent soaks are to absorb pill fillers
and to detach the psuedo from binders.
trust me if you skip dry solvent soaks your
psuedo from an ab will still come up not useuable. Crush,soak in toluene three times,
saok in dry acetone three timmes, then in xylene or toluene again, this will then set you up for and extraction with methanol or an A/b or both wichever you prefer, some pill denaturants are absorbed by both polar and non-polar fluids but psudoe is not absorbable in a non-polar until made basic.
If you do enough solvent boils/soaks you can start seeing your psuedo in crystalline for already, then you know its time for an extraction and an A/b.

Re: Confused
Start reading about solvent polarity. This will help to understand the difference in solvents and which solvent to use for the intended application.
Some are polar(can mix with water), and some are Non-Polar(usually will not mix with water).
Since pseudo/ephedrine is polar soluble, to extract one would use a polar solvent such as alcohol. To clean the binders, one would probably use a non-polar solvent.
Learn about polarity and the acid/base extraction. Otherwise you are doomed to throwing the baby out with the bath water!!!

So I'm keepin the solvent, not the mud?

Re: Confused
yes keep the solvent, its absorbs the ephi, the mud is just the talc and all the other shit the base the pills with..

OK. The powder left after boiling is added to the DH2O and finished with th a/b right?

Re: Confused
You need to post the method you are using, because in some, you throw away the solvent,while in others, you might save it.

Re: Confused
yes
the dh20 removes the other water soluble impurities, then you boil the water and get half pure ephi crystalization, after you have these u then do the a/b with them to result in the pure ephi..

So Before th A/B I use only DH2O?

Re: Confused
no,
ok here, step by step what i did,
1 crush pills put in container with water about double the amount of pill powder..
shake this around really good, and let it sit,
u'll get a white mudd at the bottom, and a milky liquid on top,(this is what u want).
syphon off the liquid and try not to pick up the mudd(it plugs up your filters)
so syphon the liquid, into another container.
add more water to the mudd and then shake and syphon again to make sure you get most of the ephi from the mudd.
once you have the milky water, filter it a few times, i say about 3, then take the filtered milk, and boil it down.
you get white powder(take this)
and disolve it in the methyl alcohol(methenol) shake really well and filter 2 times, after its filtered twice, put it in the freezer, till it gets really cold then filter it once more(this removes a wax, its only removed when u do it cold)
once u do the cold filter, take the alcohol and then boil that down. not all the way, or u'll burn the shit, just till there is very little left(microwave works for this)
let the rest evaporate, and u will see the crystals form, if u watch(its neat)
this is the shit u want to put in the a/b.
take this do the a/b and you got ur pure.

it has been SWIM`s experience that with todays pills you CANNOT add water in ANY amount in ANY form in NO part of the extraction process. i did a write up on the newest extraction process by videoeditor here is the addy to the thread: http://www.totse.com/bbs/Forum26/HTML/002238.html
man am i glad that i took the time to post that thread as i have referenced back to it 1000 times. saved alot of typing
