YOC Dirty Diamond Tek - THCa isolation from Crude

Has anyone made progress on this tek using Rosin? If so, is it required to turn the fresh press or baddered rosin to sauce first?

Hey y’all. Just purchased a ld-3 and some fritted tubes from Viking supply. I’m having trouble understanding the quick nucleation part of the dirty diamond tek. Hopefully someone can enlighten me…

It says you can nucleate any crude by adding 10% pentane. (I’m not using bho like most of you and I hope that’s not the issue) I added approximately 10-20% max to these jars of etoh crude. (Non decarbed crude btw). After adding pentane at room temp I closed the lids to the mason jars and placed them on my digitally controlled heat pad at 89 f. The sop says a covered Pyrex dish so I figured a sealed mason jar would be equivalent. (Btw does covered Pyrex dish mean like sealed ?)

Anyways I put them on the heat pad and I’m keeping them at 89f. It’s been 2 days and the crude has dissolved completely (took about 24 hrs or so ).

This is where I’m at and I’m not sure if I’m supposed to leave them on the heat pad for 24-72 hours and then remove from heat? When will it nucleate? While warm or after it cools to room temp do I let it sit for a period of time? The tek doesn’t specify.

Also this is my first time posting here on 4200 and I’m not sure how to post a photo yet. Btw I have a source extract pro that I use the make the crude with chilled ethanol. And I can use it also as a vacuum pump so I got a fitting to install on a mason jar lid for the vaccuum tube, so I’ll be able to pull a vac on these jars if I need to purge the pentane (since I don’t have a vac oven) but wasn’t sure if or when I need to do that. Also not in tek… any help would be keen! Danka

…
QUICK NUCLEATION:
.
you can quickly nucleate any form of extract including crude by dissolving it in pentane, 10% by volume seems to work fine (more dense extracts may need a bit more) pentane is easily removed via vacuum
.
put into a covered pyrex dish and place on a digital heat mat or lab oven at 89f for 24-72 hours.
.
Please note, a solvent is not required if the solution is already nucleated, pentane is just used to assist and rush nucleation.

How much pentane did you use and what was the oroginal method of extraction

Covered Pyrex trays will allow the pentane to slowly evaporate as its not airtight

@YPSIOIL did you happen to read that post you replied to? :face_with_monocle:

I added about 10 percent by volume. So to around 40 ml of crude I added 4 ml of pentane. It was taking a while to dissolve so I added 3 more ml. I didn’t realize it had to evaporate. I have been keeping them sealed. So I’m pretty sure I shouldnt open them while they are warm but if I let them cool to room temp and open them and put them back on heat pad how should I ā€œcoverā€ them. When you say covered Pyrex dish wdym. Like covered with a plastic lid that comes with the Pyrex dish? Or are you covering it with a plastic wrap or a cloth? Can I put a mason jar lid on and not tighten it down?
Also, Do I need to let it evaporate while it’s on the heat pad or after the 24-72 heat period when it’s cool? Not sure what to do and i appreciate your time/assistance. Will definitely buy more frit tubes once I get this tek down.

My original extraction method is chilled ethanol. I use a source extract pro to distill the ethanol out and get the crude. Starting material is bubble hash, and rosin pucks… I have 2 jars going with about 40 ml of crude in them. One has a bit more pentane than the other one. I could post a pic if you could send me a tip on how to post one Anyways. Thanks again for the response.

Bring to room temp and spin the band so it just is barely tight allowing gas to escape but not enter

Then you’ve missed much of the class (the section on crystallization) and would probably benefit from starting again from the beginning…

Without crystallization, you’ve got nothing to spin out.

Edit: what temps has that ethanol crude you’re working with seen? Any level of decarb makes this more difficult…thc does not crystallize

Paste works…As does the ā€œuploadā€ button circled here.

Same icon, different location on desktop.

At least once you’ve gained sufficient trust.

We might want to explore your goals for spinning your extracts as well.

There are a number of reasons one might want to perform this trick, but not all of them make sense with your input.

What is your goal?

You may find Filter Tube for centrifuge ( THC Isolate ) (need help) useful

thanks @cyclopath

Thanks @cyclopath and @HuartzBanger

the temps the crude has seen are 96-97 f in the ethanol distiller and I’ve had the crude on the heat mat at around 89 f for a few days now. Don’t think it’s decarbed. But I can try again with another batch for sure. Thanks for the help. The tek was a bit brief in the details.

…so what is your goal?

ethanol doesn’t to a great job of preserving the terpenes/volatiles, so spinning them off for reuse isn’t super productive.

if you’re just looking for a THCa source to decarb and add exogenous flavoring for carts, it should work OK. an additional wash or ReX might help.

if you’re looking for a THCa source for further recrystallization, then not understanding that you needed to (slowly) evaporate the solvent would definitely be an impediment.

One more question. In the video he took the solution off the heat and then let it evaporate at room temp. the heat is just to help the pentane dissolve the crude? Then take off heat and evaporate pentane slowly ? That would be dangerous right ? To heat pentane while it’s not sealed? Please set me straight here

My goal is to make Thca powder. I figured the terpenes portion would be unusable. I would like to make carts with the powder cuz the carts Ive been making with this crude are horrible. I can make edibles and tinctures salves with it but that’s about it. A source to recrystallize is another thing I’m shooting for yea. Thanks for your input. I am very grateful :pray:

can be dangerous either way…depending on what else is going on near by, or what you’ve chosen to turn into a pressure vessel.

do you know the boiling point of pentane? ( body temp).
the vapors are on the same order of dangerous as gasoline, and it’s boiling point is lower. taking a sealed container above the boiling point of the solvent within means you’re turning it into a pressure vessel.

Be careful what you turn into a pressure vessel.

extract doesn’t have to be completely decarbed, even a few percent THC in your THCA can severely hamper your ability to crystalize the THCA

are you squishing flower rather than bubble hash?
good squish makes for better carts than EtOH, especially EHO made from your ā€œtrashā€.

pucks from squishing flower are probably not an ideal source for making THCA powder, but without analytics on your crude, I can not tell you how problematic the heat they’ve seen will be.

This crude was extracted from rosin pucks (from
Pressing bubble) and lower grade bubble hash 25-72u mostly. But I also have a jar of crude that was extracted from flower. (Not flower rosin pucks)
Noted that the lower grade starting material will not be ideal. I’ll try it with some better grade bubble my next try.
That’s a bummer that just a few percent can hinder the whole process. It only takes one bad apple I guess :apple:

So the heat cycle is to help dissolve the crude right? Then once dissolved you can take off heat pad and bring to room temps, crack jar lids so I can start a slow evaporation. Correct ?

Basically

Ok great. I’ll give it another go. Thanx again for your time and assistance :pray:

trying to crystallize thca from ethanol extract is an adventure. i would not recommend it to anyone who does not have access to their own analytical testing.

best piece of advice if you can’t get it to crystallize is submit a sample of your extract for potency testing. Evaluate the THCA:THC ratio. your extract should be at least 70% THCA and > 10:1 THCA:THC, otherwise crystallization is going to be even harder. good luck

Antisolvent?

I’ve had success with just pentane. It is helpful to reduce as much of the residual ethanol as possible. I used some sacrificial pentane to azeotropically distill out residual ethanol levels from 20,000 ppm to <1,000 ppm. Then you can nucleate at THCA concentrations that are just higher than the saturation point. After you see nucleation, it’s all about maintaining that saturation point in the metastable crystallization window.

Keep on heat for a few days, but if it was mixed with ethanol, its a pain in the ass
