Help with Evaporating Xylene?

[OneStepBeyond]

I was performing an experiment with xylene to see what I could get with just a straight pull and evaporation from the base solution.

I started with approx 100ml of yellow xylene. It's been evaporating for a full 2 days now in a 6x9" glass dish and if I had to guess I'd say there's probably about 100ml left:roll: . It sure does smell like it's evaporating though.

Does anyone have any experience with this solvent and could maybe help me speed this along a little? I've considered mixing it with acidified water. basing and using naphtha to get it out, but I'd really like to just evaporate it and see what I get.

Xylene is HORRIBLE to evap imo.
Stinks extremely bad, takes forever, & even clean xylene doesn't seem to evap cleanly & leaves a nasty smell.

I'd seriously reccommend you salt out your spice from the xylene with either fasa, fasi, or fasw.

If your into chemistry, salting out & cleaning up a full spectrum extract can actually be quite an enjoyable process :thumb_up:

I was blown away by how much other stuff less selective solvents pull.
Litrerally watched a 5g chunk of jungle spice from 100g mhrb dwindle down to an appropriate yeild of pure white.

It's strange to watch. The dmt seems to precip & grow into crystals first, then the jungle precips & coats the crystals.

I do have a bottle of fumaric acid on the way that I ordered online. Maybe Ill just wait for that and salt it out. At this rate, It'll probably get here before the xylene would evaporate anyway.

I was looking for jungle spice (incl. DMT) to make some changa, but I don't want it if it's going to smell like this. I've got to do something with it, there's likely (hopefully) a pretty hefty dose of DMT locked up in this stuff.

Really, don't evaporate xylene. That is such a bad idea. Even salt with citric acid in water if you can't do the fumarate thing. Pretty much anything except evaporate. DMT acetate is said to be soluble in xylene, so vinegar won't work, or not very well at any rate.

It sure does smell like it's evaporating though.

It stinks!

I believe the full spectrum of alkaloids does come out with salting.

It did from limo anyways. I ended up cleaning up a 5g chunk from 100g mhrb so there was surely some other alkaloids in there & my separation was pretty good so it wasn't base.

 

[OneStepBeyond]

Yeah, you guys are right. I have to say for the record that anyone reading this and thinking of evaporating xylene pulls to get full spectrum goo, don't bother:thumb_dow .

Plan B it is. The xylene has been transferred to a sealed jar put away in a dark place, awaiting my shipment of fumaric acid.

Hope all goes well for you.
looking forward to seeing your final yeilds

Patience seems to be the key with salting out. That & washing :lol:

Evaporation happens when a molecule gets excited (is given energy from somewhere) and flies out of the fluid as a vapor. You can excite more of these molecules by giving them heat energy. Perhaps use a warm water bath, for instance.

I'd avoid telling him to heat the xylene ice.
He's talked already of the stink, i don't think the area he's evapping in is very well ventillated area & that smell leaving windows & vents may catch attention of neighbors rather quickly, especially when heated & producing more concentrated vapors.

Good point. Chemical odors sure do get alot of folks caught. I'd extract from the xylene 3 times with acid, and move into a different solvent.

Where is this said please? I would like to know more about that claim.
The matter is referred to here Solubility of DMT acetate in Xylene
stating the solubility is a no concern.
For the record: swim salted out very successfully with vinegar out of toluene.

For the record I had it in a sealed room with an open window. It did smell a bit inside the room (esp. when compared to naphtha) but it wasn't that overpowering and I wasn't hanging out in there. I doubt there would have been a noticeable smell outside anywhere a neighbor might be hanging around.

In any case I've already put the xylene away, and I won't be evaporating it again. It was just an experiment that didn't work out as planned. Maybe someone else considering this course of action will read this thread and change their mind. I looked for a thread like this before I started bit I couldn't find anything.

Comfort has nothing to do with it. You should wear appropriate PPE when working with any chemical. So unless you want solvent vapor in your lungs/eyes you need a respirator and goggles if you're going to be working with solvents in a relatively unventilated area. You should set up a fan and position your solvent so that its vapor can quickly evacuate the work environment.

Bear in mind that most meth labs are often discovered because of 'chemical smelling' odors. This means you need to weigh between your safety and your freedom. If you cannot harmonize with this balance then perhaps try a different extraction technique.

I never said anything about comfort. I was just saying it didn't smell that much. I wasn't sitting around breathing in vapors while it evaporated. And the room was pretty well ventilated. When its well below zero outside, an open window exchanges quite a bit of air.

And you'd have to get pretty close to that window to notice any smells. It's not likely in my situation. Thanks though for the suggestions.

I did a vinegar wash on my xylene and when i dipped my finger in xylene and smelt it and it still smelt like vinegar! What Infundibulum says about dmt-acetate being a polar molecule makes sense but I am gonna boil of the xylene and see if there is some dmt-acetate in there just to see what is causing the smell.
