Ketamine crystals have and oily residue the BURNS!!! how to clean and recrystalize??

[Lonewolf1]

SWIM has recently come into possession of some ketamine HCl crystals and when rubbed in between your fingers you can feel and see an oily residue, the Baggie smells of some chemical and When snorted it burns like nothing SWIM has ever felt!!!!!! Dangerous acidic feeling bleeding nose bad. (To be noted SWIM got high from snorting the k b would not injest again)

there is some kind of dangerous residue connected to the ketamine. SWIM is in no way a chemist but there is quantity enough to reach out SWIM is intelligent and keen to learn.

SWIM'sbreakdown was that if SWIM was to dissolve the ketamine in warm distilled water the ketamine should dissolve and detach from the residue? And perhaps if SWIM was to boil or simmer the solution, the residue might evaporate? Or at least make it possible to separate? Maybe depending on what the residue is? How would SWIM find out what the chemical is? And how to proceed from here?

SWIM's bag is full of beautifully formed crystals that are way to dangerous to injest and they need to be cleaned.
SWIM reaches out asking for help in laymans terms how one could potentially separate and recrystalize using basic home utensils.

First, we don't swim in this forum. Everyone knows it's you and using SWIM just makes the text harder to read. You should take a moment to read the rules.

It's hard to tell what kind of residue that is (is it water-soluble or not), so I don't know if recrystallization with water will help, but let's assume it does. Basically you have the idea right, that's what I'd do at home as well. Dissolve the crystals in water. Is there a lot of the residue? It should start floating on top of water if it doesn't dissolve, which I'm almost certain it won't. You can try decanting, but you can also try filtering with something like a coffee filter to separate water from it. Trying to evaporate the residue will most likely not work, because typically crystalline products have already undergone vacuum drying which means that oily thing is not really volatile. So after filtering assuming the residue is left on the filter, you can evaporate the solution and you should be left with clean ketamine.

Awaiting peer review from fellow users.

There is a lot of residue, the crystals are water soluble and the oily residue does rise to the top, perhaps dissolve the crystals in water and filter the top oily layer off then evaporate the water down?
Would distilled water be necessary and if so what type of stores sell it?

recrystallize from hot water

As a somewhat related question - I've had at least two different batches of N-ethyl norketamine from different sources. One was certainly better synthed / purified than the other, but both caused unbearable irritation to the nasal mucosa - not really an acute burn, but intense discomfort / swelling afterwards or even nosebleeds. I seem to be somewhat sensible to ketamine though, and restricted myself to sublingual use for now (I don't like ketamine that much anyway, it's too short acting and expensive in HiQ.. but since MXE is gone now, well...) - but really pure ketamine is nothing in comparison to these NEK batches.

Is NEK just so much more irritating, or were this impurities?

And what can be done to avoid the irritation with ketamine, is it about osmosis, pH, ...? I know that sometimes ketamine is used for pain as a nasal spray solution with somewhat like 20mg/ml.. so it has to be possible to avoid the tissue irritation.

Pure MXE for example is not irritating at all for me, if I did it too much it would dry out the nose a bit, but with just some saline spray there is no discomfort at all.. (with K saline helps a bit, but it doesn't do the trick) so it can't be about the arylcyclohexylamines as a whole (even when the MXE doses are way lower of course.. but also low-ish antidepressant / anxiolytic K dosages like 20mg cause tissue swelling for me)

Thanks!

No, N-ethylnorketamine is not supposed to be more irritating than ketamine itself. However, if you want to have a longer chain than methyl on the amine, it can get more messy in the last but one step, so a side product is more likely, but it is separable from your target intermediate. If there is anything oily, then it's most likely a left-over, but there might also be water-soluble contaminants present.

Y'all need to get in with someone who owns a GC... guessing at purity is kind of fraught with peril.

Yeah, I'd love to and hopefully I will be able to do that some day, but at the moment it's inaccessible for me as it is for most hobbyists - afaik even the best openly accessible drug testing possibilities like in Switzerland (Zürich - require personal consultation) or Spain (50€ for non-citizens, one's health should well be worth that, but we all know the reality) don't do real qualitative and quantitative GC/MS analysis, or am I wrong? They only tell what the key ingredients and impurities are, as long as they are in their database.. but maybe they are better than I think.

Regular lab analysis is so prohibitively expensive, and associated with the fear of legal consequences. :/ In many countries there is no possibility for drug tests at all, besides Marquis etc. and even these aren't exactly welcomed by the authorities.. I know of customs seizing these reagents and possibly exposing the buyer to legal consequences.
