IPA turned my white spice dark yellow!!
- Thread starter Psyren
- Start date
Usually i freeze precip it out so the spice isnt exposed to air that long. With this its gonna take atleast 2 full days next to a fan to dry and its already way more dark than im used to.. Where did the color come from?! im wishing i never messed with it

Is your IPA clean?
Its posible some oxidized. Sometimes it also happens that depending on how something is crystallized/retrieved, the appearance change, even if content doesnt really change. So the same substance may appear as an oil or a crystal, sometimes, depending how its done.. Though the very clear color change does seem to indicate something else is going on, possibly oxidation. Let me get one thing straight though, it changed color before evaporating the IPA, not after? So as soon as dmt dissolved in it, the IPA got noticeably darker?
What if you get part of it and just try to recrystallize it by dissolving in small amount of naphtha and re-freezing, and the other part just let it dry, keep scrapping and re-scrapping and letting it air dry.. See what you have with both attempts.
Just remember not to throw anything away, it can always be saved.

I used a brand new bottle of 91% IPA from walgreens. I did get the IPA warm before adding it to the spice (idk if that step was necessary).
I shouldve taken pictures. But the spice I started with wasnt glass shard clear/white, it was more off white/light yellow powder. I did a STB extraction with food grade NaOh and naptha. I never let the mix sit long an pull very early yielding me with spice that has very little discolorization/oils. Freeze precip and usually never reX cause its never discolored.
But this one time i try redisolving said spice in IPA the IPA immediatly turns yellow and of course the color has remained as the IPA has evaporated.

not only oxide but maybe some cycling into a carboline, NMT darkens too but does not form an oxide..., but the betacarbolines can also form oxides...
very very common
keep your working colder to minimize it, heat tends to speed up this reaction

Do you think putting the spice in a coffee filter then pouring cold IPA over it would be a better idea? Idk i shouldve never messed with it.
Most people hear work with warm solvents and such so thats why I warmed the IPA.
So are you suggesting that by mixing my spice with warm IPA and evaporating it, its begun to change the molecule?
And thanks Albert & Endlessness for the quick responces.

Do not panic or get paranoid about colour changes; all is going to be fine. Spice always tend to appear more coloured when in solution than in crystals. As long as your evaporation ends, you've scraped the solids and compared them (at least mentally) to your starting material there is no need to worry or ask for more feedback. Most likely your spice will have the same colour after evaporation as the one you started with. It may though be a bit more yellow, but that is also fine; most likely a negligible amount oxidised, in which case you haven't ruined or lost anything but your desire to immediately smoke the whitest of the spices!:d

Very true. Im just used to doing this a certain way, then i change it, and obviously the final product changes. Im sure itll still be active, i just dont like or understand the dramatic color change.
On a positve note, its much more crytalline, like pop rocks. While before it was more powder. But the greedy man in me wants the clear glass shards :twisted:
Also consider that just about anything finely powdered tends to look white. Maybe it wasn't so white as you thought. I've never seen white chunky freebase spice crystals, they are always some shade of yellow, even if just slightly yellow.
Nothing to worry about, really.

I notice "dramatic" color change after one week after redissolving in acetone, when the same batch not redissolved keeps its white color for months. I guess it's due to exposure to oxygen.
But in general, yellow is just as good if not even better so no worries there!
Isn't it the effects we are after?

Interesting, but are you comparing undissolved spice vs the acetone-redissolved? Or undissolved vs acetone-redissolved, then evaporated? Or dissolved in acetone now vs dissolved in acetone after 1 week?tele said:

I'm comparing clean crystal freeze precip (very slightly off white) DMT to the same batch but redissolved in acetone. After one week the redissolved stuff has changed color noticeably while the white crystal form DMT keeps it's white off white color.

Well, then that's not a valid comparison since you cannot compare dmt colour in crystal vs dmt colour in solution.tele said:
But please, I think I might be misunderstanding your post, since the way it is worded makes it open to more than one interpretations. What I read is that you dissolved freeze-precipitated white-orange spice in acetone and it changed colour. Again, did you evaporate it to make colour comparison? And why, out of curiosity you'd leave it in acetone for 1 week? Or your redissolved stuff was changing colour while acetone was evaporating. Please try to be more elaborate and punctual with the information you post. Again, if I got you right (as per my first sentence) then your comparison is invalid and your conclusion flawed.
Infundibulum said:
I took it as comparing white spice, with the same white spice only its been dissolved in acetone and been evaporated. After a week, the one thats been dissolved and evaporated is more yellow/discolored than the orginal.
Psyren got it right.
Why would I compare the color in solution when it evaporates in couple hours, and you ask why would I leave it for one week in acetone? I don't know why anyone would redissolve it in acetone and then put it into airtight container just to look at the color, for a week.
I guess I just didn't mention "after redissolving and evaporating" and that made things unclear, sorry for that but I didn't think about it's possibility to be viewed as "DMT left in liquid acetone" at the time.
I meant after one week after redissolving(and drying and scraping, I thought this was obvious) the DMT changes color more than the same batch not redissolved but in it's original freeze precip crystal form.
