Extraction - NaOH DXM extraction...

[Toxicity]

This method sounds a little crazy, but then again, I don't know all too much about DXM. Would this extraction method work?



----------------------------




First off, I don't recommend that you take Robotussin or any other
substances against there intended uses or illegally, and this
extraction method is purely a chemistry experiment.




The bottom line is you need Sodium Hydroxide (NaOH). Medical grade
is needed. I have heard that you can get NaOH as Lye for flushing
your sink. However, I specifically recommend against this without
full study on it and knowing all the ingredients, because it
probably contains strychinin as well (thats a joke!). But
I really don't know what else is in hair clog Lye and you probably
don't either. You will also need a funnel and coffee filters.
Filters smaller than 10 microns will take forever to drain.




You will need about 2 mg of NaOH for each four ounce bottle
of Robitussin Extra Strength Cough. Only get the kind with
DXM only as the other crap will precipitate, you will die,
and your friends will write stupid anecdotes about how stupid
DXM is to drug net, because they couldn't face how stupid
you were and now your dead and can't drink chocolate milk
with them.




First, make a solution of about 100 ml of cold water,
I recommend distilled, and am not responsible for conflagrations
caused by tap water use. 100 ml is about a cm of water in a
coffee cup. Stir in your NaOH (1/4 teaspoon or 2 mg). It
will take a bit to dissolve. NaOH will heat up the water
real fast so if you are using larger amounts be very
careful.




Now pour the NaOH solution slowly into your Robo while
stirring. A white milky powder will form where they hit.
The extraction will occur quickly. There is very little
DXM in Robo and it will all be done quickly. If it
IS NOT REALLY OBVIOUS THAT white powder is coming out
of solution anymore, than you are done. It will not
take much so don't keep pouring in more solution.




Now pour your solution through the filter and funnel.
This will take a bit of time. Then rinse the container
in case some powder was left in it. Then pour
water through the filter until all the red dye is pretty
much gone. Let the filter drain for bout an hour.




Open the filter up and let it dry on a plate. You
can heat it a little (150 degrees) to speed this
process. Then scrape off white powder.

Wouldn't that white powder really be DXM freebase and not a salt. I think that by adding such a strong base solution to your robo would cause it to act with the HBr making H2O and NaBr salt + DXM freebase and all the other solvents in the robo. When drained off, you would have DXM freebase and NaBr salt as the powder. This would likely be a dangerous combination to consume. I have seen several other extraction processes on the web though that use a base extraction, but you then have to add an acid to the freebase to turn it back in to the salt form form consumtion. I'm not that advanced in chemistry, but I think that's close.

i've been wanting to try this method but idk where to find pure lye.
they have it in detergents but i'm not sure if that's effective.

EDIT: SORRY mistake red devil lye isnt just lye sorry not sure now about it


is it possible to just heat up the water in the microwave? then you just add the hot water to the robo and stir or is there another reason for the lye?


i heard about using just the hot water when using sucrets losanges...crush them to a fine powder and pour them into the hot water and stir


how is this powder used?Edited by: pokergod0588

You don't have to heat up the water itself, NaOH+H2O is an


exothermic reaction - just mixing the two will generate some heat.





The point of using sodium hydroxide is this: Dextromethorphan is an


alkaloid - it can exist in freebase form or as a salt (DXM HBr,

</span>hydrocitrate, etc.). Mixing DXM freebase with an acid</span> </span>will cause the


freebase to convert into salt form, name depending on which acid you


happen to use...





So, therefore:


DXM HBr = DXM Freebase + Hydrobromic Acid,


DXM hydrocitrate = DXM Freebase + Citric Acid,


DXM HCl = DXM Freebase + Hydrochloric Acid.





Well, I'm sure you get the point.





So knowing all this, you'll probably guess that the opposite is true:


mixing a DXM salt (in the case of the syrup, DXM HBr), with a base</span>


will convert your DXM salt to DXM freebase. And NaOH just happens


to be a very strong base.





So anyways, it also just so happens that DXM freebase is not</span> soluble


in water (syrup is water-based). So it's going to precipitate out, and


that's the white milky powder shit that you're going to see when you


mix syrup+NaOH.





So that's the point of NaOH in this reaction.





Alternative to Filtering:</span>


You can also take your syrup shit+DXM+NaOH mixture, and add an oil


based organic solvent (naptha). Since freebase is soluble in oil, it will


dissolve into the naptha which conveniently will also float on top of


all the water-based shit. You can then drain off the water layer,


keeping the organic layer (separatory funnel/plastic bag method), and


then evaporate off the naptha. Sounds like a lot, but it's really very


simple.





Just beware of toxic fumes.

I tried this with a cheap bottle of DM and it DIDN'T work, I don't know if the guaf effected it.

Try the alternative filtering. two post above

In ones dreams put an equal amount of robo and distilled</span>
water in a large Mason jar(any large enough GLASS jar with lid
works) than put the lye+water solution in the large mason jar,
than add 20 - 50 ml of napatha (purple zippo lighter fluid).
Shake for 5 minutes one will feel the heat. after five minutes of
shakeing dump into a large plastic bag. let the bag hang for 20
minutes at least to make sure everything has settled. The goodies
are in the lighter fluid. cut the corner of the bag drain the bottom
layer back into the jar watching closly. AS soon as ALL</span>
the bottom layer is gone pinch the conrer of the bag. Let the
lighter fluid drain in to a pyrex dish. Let dish
evaportate. scape powder. One can use fans and hair driers
to speed up evaporation

Apparently guaifenesin can screw up the NaOH reaction... creates an

oily layer or some shit like that.
