is this solvent good?

So SWIM is still trying to find proper solvent for spice extraction since he moved. His ideal is obviously a green tek like lemonene, but right now he cant get it. So he goes for normal extraction.

He found xylene, and a couple of different types of naphtha. One that says 'heavy and hidrodesulfurated' naphtha. He once made a thread and someone said that the 'heavy' part sounds like it would take ages to evaporate. But what about extracting with xylene, and then just running warm heavy naphtha after evap to pick up dmt from jungle spice, and then into fridge? this way he wouldnt have to evap it.. sounds ok?

or he also found a 'light hidrogen-treated naphtha'.. What about that?

or what about plan white spirit?

Thanks for the help! btw, I thought maybe other people could post in this thread when they also wonder about a specific solvent
 
SWIM had the same question a few days ago - he has a gallon of xylene, but didn't want to have to do any/much evaporation. So he went shopping, and all he could find was white spirit with mention of hydrodesulphured naptha, and light aliphatic naphtha (bartoline white spirit). He just went ahead, figuring that it would be ok for a freeze precip.

He tells me that it seemed plenty good enough; his end product after feezing smelt strongly of naptha for a day or so, but under a cool fan the solvent scent was lost and the product was well crystalised. Perhaps it would be wise to wash with ammonia, dissolve in a cleaner evaporating naptha (eg. lighter fluid, which evaps cleanly in his experience, but costs about twenty times as much money) to recrystalise...?
 
Hydrodesulphured naphtha isn't treated with sulphuric compounds, hydrodesulphurisation is a process for removing sulphur compounds from petrochemicals.
 
why would you want to separate dmt from jungle spice? the xylene extracted stuff is amazing!

oh and you dont need a nonpolar solvent anymore for extracting dmt! check out my tek in other extractions :D

there were two things.. one was hydrogen-treated naphtha (which I still wonder what it is and how it goes for SWIMś purpouses), and another was hydrodesulphured naphtha, which indeed is the removing of the sulphur..

btw SWIM found another solvent that says 'White Spirit, turpentine substitute'. Running a search on the information numbers (CE and CAS), it comes up withnaphtha, intermediate fraction. So I guess its ok heh? Its not hydrogen treated and nor the 'heavy' one.


btw fuego, yes I saw your proposed tek but fact is, nobody really did it yet, SWIY only did with already some extracted spice, so until someone actually does it, its still theory. SWIM will be really interested how it turns out, though, but he has no spice and needs some soon as he'll have a perfect opportunity for using it, so he'll go for the old methods. :)
 
White Spirit IS a turps substitute, isn't it?
Anyway, on SWIM's bottle it says
"Contains: naptha (petroleum)
Hydrodesulphurised heavy
UN No. 1300 Turpentine substitute (white spirit)"

He says it works fine for extractions. The only problem is that residual solvent takes a while to evaporate - patience solves this problem:)
 
bump to old thread

SWIM is still on the look for pure naphtha/hexane/heptane

So far all he found had some aromatic like xylene mixed in.

Now he found one brand that says: Heavy hydrogenated naphtha.

It mentiones it is des-aromatized (or basically that the aromatics is removed), and that it has low toxicity, considered a 'new generation' solvent. Which sounds good.. but what about the fact that it is 'hydrogenated' ?

It doesnt matter if it evaps slow because SWIM will only use for recrystalization.
 
From what I can gather 'Hydrogenated' means that more stuff has been removed like alkenes (Olefins), as Heavy Naptha contains more of these compounds, therefore making a more purified product.

For pure(ish) naptha you should look for petroleum spirit. As for heptane/hexane?? It would depend where in the world you live. SWIM can find it in the UK.
 
if thats what hydrogenated means, then sounds good..

yes SWIM moved to europe recently and he cannot find proper naphtha anymore (neither petroleum spirit neither heptane/hexane). Only mixed stuff.. also he is in a small town so that for sure makes it harder... but if this one I mentioned does work and 'hydrogenated' is not bad (like hydrogenated fat in food haha), then it sounds perfect for recrystallizing the stuff SWIM has

Zippo Lighter Fluid has been reported to work for many Europeans without access to VM&P Naphtha or Colemans Fuel.
My friend will be testing this within the next week, along with Bestine (rubber cement remover [heptane]).

Will report back with how successful those products are for my friend.
 
To update;
Zippo lighter fluid works fine, it evaps clean and my friend's last test extraction left her with beautiful creamy white spice.
You can get hold of this fairly easily.
