Hi Newton3rd,
I'm also just joined the nexus this weekend. So first congrats your pictures look like a successful extraction. I also like the Noman TEK. The waxy substance you have after freezing your organic solvent is normal and not necessarily caused by impurities in your solvent. You did the solvent evaporation from 5 mL to 0 and had no residue. The amount of oily, waxy substance you have now is most likely much more than could have been in your lighter fuel. This residue is probably plant fats and other alkaloids, together with more DMT and similar stuff.
Whether your spice is good to smoke? Hard to tell from just the picture, it does not contain very big crystals but looks okay (I've seen worse). There is an "is my spice ok to smoke?" thread on the nexus, check that out.
If you want to get beautiful white crystals, I recommend the following.
First get a solvent you are absolutely happy with regarding purity. Check out this thread, it is exactly about your problem:
https://www.dmt-nexus.me...aspx?g=posts&t=14772The problem is that "naphtha" has many names and depending where you live different stuff with different intended applications is available. Generally I would try to get some solvent which is intended for medical applications (e.g. removal of band-aids from skin) you can get this even in your local pharmacy (expensive!), better avoid fuels as they have generally lower requirements for purity (which does not mean that there aren't high quality lighter fuels which are fine).
Second, recrystallize your product. This can be combined with a little A/B extraction of the waxy residue you may have left from your extraction. You will be surprised how much DMT is in there. The procedure can also be used to further purify the material you have shown. Be aware, that every purification results in loss of some material. It is always a trade of quantity versus quality.
For the A/B extraction, I recommend the following procedure:
Dissolve your crude material in water, acidified with citric acid (this is readily available in food grade, even in supermarkets or online in bulk for very cheap). Notice that DMT free base does not dissolve in normal water, but once acid is added it quickly dissolves, if you read the chemistry 101 thread
here, you know why. Use as little water as possible! Now perform a naphtha extraction on the acid solution. You can use your zippo fuel for that, because the naphtha does not pick up the DMT from the acidic solution, only fatty and greasy impurities. Extract at least 2 times. Use a small, tall glass jar with lid or something similar. Keep all volumes low to save solvent.
Now make your aqueous phase basic again by adding concentrated NaOH solution in water (NaOH premixed with water) until the pH is >13. pH paper is helpful, but you can see without it when you are basic enough, as the DMT becomes insoluble in the water again and the whole solutions turns from clear to very cloudy. When this happens, maybe add a bit more base, then start again with naphtha pulls (same procedure as you did initally), this time using your high quality solvent. Cool your naphtha pulls (first fridge for half a day, then freezer). Slow cooling gives bigger crystals. You will see the difference. The basic aqueous phase should be extracted at least 3 times to recover all (well most) of your DMT. Before you go for your first travel, read the smoking TEK threads. Inhaling DMT is not so easy but if done correctly your jaw will drop from amazement. Be careful, it is powerful.
Best wishes!
