QWISO with separation.

[NotGuilty]

Well last night I was bored and decided to take some qwiso and see about purifying it further. Lately people are talking about hexane extractions and such, so I decided to try something. Separation of the oil soluble and water soluble extracted cannabinols.

About 300ml IPA was poured over about one ounce of old, 1 yr, trim in a funnel. Total contact time 35 seconds-ish.

Evaped 250 mls and got about 1.5 grams or so of qwiso for my stash

Took the other 50, added 50ml Toulene. Looked like clear piss still like good qwiso rinse should. Added 30 ml water and watched the magic. Toulene rose straight to the top, with the THC looking piss colored still. IPA and water went to the bottom and turned pretty milky. Took off the top layer of Toulene and evaped. Resulting in about 1/4 gram, maybe less.

The qwiso was gummy, yet firm. brown/amber. if the glob is thick its somewhat black. stringy with the strings easily making curved loops.

The toulene one shatters like real good BHO at room temp. same color, slightly black when thick. when warmed slightly stingy and the strands make more jagged curves if you know what i mean.and when worked with the pin very gold, shimmery.

Haven't and probably wont smoke the research batch. Saved it though.

Really? no comments?

yet someone can ask "how do i make thc oil", for the hundredth time, and get 10 replies.

Dude - it's extremely lame to bump your own thread and give everyone a hard time for not replying..

Maybe if you had some pictures of the process or actual feedback on the quality of the end product you might get a discussion going.

pics or it isnt refined !

sorry about the bump.

i was thinking maybe someone had knowledge of toulene to share, or other experiences. I will try and get pics soon.

totally interested.

I was also wondering "why toluene?". I suppose it's more readily available than ether or the other solvents that are more frequently mentioned in the various recipes for refining solvent extractions (like the isomerization process summarized here).

In a brief look around the net for lab grade toluene (i.e. cleaner than paint thinner grade toluene), it doesn't look too cheap, maybe US$15 / liter for the lab grade stuff. Ether seems to cost quite a bit more, though...

I did an evap test first, as with all solvents I use.

I have seen the method mentioned above, and also seen this done with hexane. The one thing I don't like is the 110 C boiling point of the T. I think a vacuum purge is required.

Thanks for the intrest, and ideas!

Interesting stuff of course

Always been a big mystery to me what gives oil its qualities, it seems to me there is never two equal batches of oil, theres always some difference in viscosity, colour or even effect.

Have you ever tried making jelly hash (mixing in some dry sift into the oil)? for some reason it gives me a much stronger effect than just the oil on itself, even if the drysift is from the same material that you use to make oil. Would be cool to hear if anyone has the same experience or im just "special"
