Hi there,
i already posted my first thread in the Welcome area, and after an introduction of myself i asked the same question i'm writing here, maybe this is the right place for it, so i'll copy and paste the question, hope you can help!

I'm going to do my first STB extraction, and at the moment i'm buying the required items..

I've ordered my first bunch of MHRB from mh-uk (you probably know that website, and i hope i'll receive my mimosa, it seems that they had some problems in the past....), so during the wait for it, i'm starting to buy the other things that i need, and i've got almost everything. The only thing that i'm missing at the moment is the solvent.
I read everything about the best ones, etc etc.. Now, because i can't find pure naphtha or heptane or anything else in my country (i live in EU), i ordered some Ronsonol from a big seller on eBay, but because they are not replying to me (and i haven't paid yet), i went to a DIY store to search something by myself, something that could be ok as well even if it's not pure naphtha..

So, at the end i found 2 products that seems to be quite in accordance with your advices:

1)The name traslated is something like "Epoxodic Thinner" , and in the Ingredients is written: TOLUENE , XILENE.. Nothing else.

2) The name is SYNTIACOL, and in the ingredients it says:
Naphtha solvent (petroleum) light and aromatic, Toluene. Nothing else.

Now, i know that if i want to be sure that a solvent is good or not i should let it evaporate and see if will leave any residue..
Anyway, i'm interested in your opinion about these two solvents, what do you think about them? Could they be ok?

In my personal opinion, the 1 should be ok, since xilene e toluene seems to be good solvents, even if they'll leave some yellowish things at the end, because i know they bring with them more alkaloids.. My concerning is about xilene and toluene together... Are them ok together?
The 2 in my opinion could be better than 1, since the biggest part of it seems to be light naphtha, with some toluene. But here i have two worries:
1) Could the fact that it is aromatized be a problem? I mean, if there are other molecules in the compound that comes from the fragrance, couldn't it be "dangerous" in some way?
2) Again, naphtha(light aromatic) + toluene can be considered a safe combination?

Thank you all!

First, you need to decide if you want to freeze precipate or salt out from the solvent. Freeze precipation allows you to put the solvent with the DMT in the freezer and get the DMT to crash out; salting and then converting to freebase is a more complicated process.

If you want to freeze precipate, you must use either petroleum ether, Panel Wipe, low odour (important that it's low odour) white spirit or liquid paraffin (listed in order of preference). Ronsonol would work too. All of these can readily be bought from UK suppliers.

If you want to salt out from the solvent, you can use d-limonene (recommended), xylene, toulene (all of these are aromatic compounds) or a combination; any solvents that work for freeze precipation will work for salting too but not vice versa.

Both of your solvents are only good for salting but not freeze precipation because they contain aromatic compounds.

If your in OZ (according to your location) and getting bark from UK.
Be prepared for it to be held at customs...OZ customs xray and look at all organic material coming through.
If they recognize it for what it is...you may never receive it.
Have a plausible excuse ready just in case..

Hope it comes through for you though..

Thank you N6. So, it seems that aromatic compounds are not good for freeze precipitation, which was my idea. Thank you. I'll try to find something else here in my city, or i'll wait to buy something from ebay.



Hey Cyb, actually i'm not in OZ, but i'm moving there in a couple of months, for a complete change of life. I'm in EU at the moment.
