Recently, I washed my isolates, and here’s the remaining solvent.
I left this jar in a dark, cold place (on the balcony). The weather in my city has been around 2°C to 15°C these days.
After two days, I noticed this:
What are these? Leftover THCa crystals or something else?
Would help to know more
Wich kind of solvent
Wich procedure was solvent used for
What was extracted with solvent
Etc etc
Thank you for reaching me! @Roguelab ,I used butane to extract (BHO) from flower that was trimmed about few monthns ago. I waited for sugars to form, then used the centrifuge technique to trap THCA crystals inside a bag filter.
Afterward, I used 25 mL of hexane to wash 25 grams of THCA, repeating the process twice (a total of 50 mL of hexane). I’m not sure if I did it correctly, but to wash my THCA isolate, I used a 1:1 ratio with cold hexane.
In this beaker is what remains from the hexane wash (around 50 mL) and about 10-15 mL of 99% ethanol (I used the ethanol to wash THCA/… that was stuck to the wall of the beaker).
The solvent was completely pure after washing. with nothing in it. I placed it in a dark place, and after one day, things started to appear inside the solvent.
Hmm ok so rule of thumb
The more C s an alkane has the better they are at dissolving thc-a
So using hexane as a rinse solvent it has to be COLD -20C or colder
At the same time hexane when cold
Will crash our cannabinoids fairly well
Thefact that there is ethanol inside makes this observation a bit more complicated ethanol is a good solvent and I would think nothing would crash out at the ratio and temp you describe
Was it pure ethanol or denatured ?
I would assume it to be thc-a crystals
But concentration of thc-a
Presence of ethanol in solution
Likely terpenes in solution
The not so cold temps do raise questions if this is thc-a
I would suggest to place the breaker
Covered plastic wrapped in a freezer and give it 3 days and check amount that crashes out once collected
Dry out and try to find more of it s property s like melting temp
Another thingy hexane is a great solvent BUT make sure you purge it of your consumable well and good
Wich basicly means 48 hours under vacuum at room temp
Yeah, probably THCA based on those videos. Echoing what Roguelab said, your hexane was too warm and likely dissolved a bunch of THCA during the wash. Then it evaporated a bit and cooled down a bit and THCA started crashing out.
Yes this theory would make perfect sense IF no ethanol was present we are all aware of the difficulty to crash thc-a in ethanol
And it s presents is a thingy
Never worked with solvent mixtures for crashing thc-a but can t think of anything else that crashes out other than a ethanol denaturant for wich it seems to much
I’d argue it’s difficult to produce reliable repeatable facets in a timely manner, and flip side, cold crash with any meaningful amount of solvent when using etoh. But this isn’t exactly that.
This is such a miniscule amount and far from diamonds or sugar. I’d lean it is just a small floating plume of thca.
OP, just fish out the white and test it in a bit of water. Dissolve? Consistency/texture? That would either give us 99% surety it’s thca or just confuse us more.
depending on the how the input was generated, centrifuged “sugar” can retain fats and waxes, which are a) also soluble in hexane, b) not so soluble in ethanol c) tend to flocculate in a similar manner
so while I’m with the crowd suggesting that hexane grabbed some of your thca, and you could be looking at it, I’m also inclined to suggest it’s ppt fats/waxes… I’ve probably still got the jar of ethanol I washed my fuge out with yesterday, and I’ll let y’all decide how similar they look once I get in and locate it.
solvent may have been transparent, but I’m betting it didn’t change color on your balcony, so “pure” is far from correct…and as we can clearly see, there was all kinds of shit in it…
not trying to give you shit. agreed upon vocabulary is required, so you can learn by talking shit over with others. nobody you’re discussing this with would use “pure” for the amber colored wash solvent…even before you let it sit.
if you think about it, “pure” is a horrible word choice for “mixed solvents, left over from washing”…you even explicitly stated the ethanol had THCA in it…
