Migrated topic.

Sorry for starting another topic on solvents but i culdnt find the answer to my question from searching.


Is xylene just as good naphtha as a non polar solvent.

I have always had excellent results using naphtha in the past but xylene is cheaper and if it works just aswell i may switch over.

Xylene is cheaper than Naptha for you?
Geez where I live Xylene is more than 3x the price of Naptha!

Regarding your question, I'd most definitely be sticking with Naptha for a few reasons. Although if you alter your technique accordingly you probably can use Xylene without a problem.

Basically, Xylene is a 'broad spectrum' solvent. These heavy duty solvents (similarly Toluene) will rip the crap out of anything. This can be a problem when working with plant materials as they contain a lot of extra non-polar crud that will be extracted along with the goods making for a messy result. Plants are usually extracted with more gentle solvent like Naptha.

If you really want to use Xylene, I would suggest:
1. Acid cook then extract with Xylene (or do a straight-to-base)
2. Wash your Xylene with room temp acidic water
3. Extract your goods from the combined washes in step 2

That's basically a double A/B.
DMT Salts are freely soluble in aqueous solutions, so you don't need heat at step 2. The benefit of step 2 is that the goods will come across to the aqueous leaving behind the NP crud in the Xylene.

I'm don't think dmt will freeze precipitate out of Xylene so you'll probably have to evaporate to recover your product. Evaporating straight Xylene pulls from plant material is guaranteed to be a mess

what if i peform a xylene pull (using an STB tek).
Let the xylne evaporate and then dissolve whats left in a little bit of naphtha.

Would the naphtha pull out the dmt from the xylene pull and leave behind all the unwanted stuff?

That might work ok, I'm not really sure
The only problem I see with that is that the dmt will be mixed in with a significant amount of NP gunk that doesn't normally dissolve in Naptha. This may lead to the dmt being 'protected' by the NP gunk making a large portion of it unable to migrate into the Naptha

I say try the double AB 😉
it's not that much more work and should give you a pretty good result

Yes it will work (speaking from experience). However, you will need to do at least 1 freeze preciptitaion and 1 recrystalization. Otherwise you will still have some gunky, oily stuff.

thanks acolon thats exactly what i was looking for.

I always freeze precip so that wont be problem.

Ill try it on my next extraction. And let you guys know how it goes.

Dont you like dirty dmt?

hehe YEAH!
But within reason.
1. I used to double A/B for pure white, that's too clean, the depth in the experience is lost
2. Recently I freeze precipitated Naptha pulls straight from the phosphoric acid cooks, too dirty (just makes it harsher to smoke, and harder to work with)

Next time i'll rex 2 three times or so
