sorry wrong term i know its not boiling i mean the co2 off gassing, the 221 was in “F” but i only said that because i figured most of you all are in the states, we are in canada haha

220f in a vac oven for 20 hours. Turn off heat and let cool to room temp before releasing vac

reminds me of a duet I can never quite get out of my head.

I feel sticky, oh so sticky
I feel sticky, and gritty, today!
I know it’s only BHO, but I like it…
when making therapeutic cement, one can substitute “RSO”…

What are the latest updates? are you now finding success?
Are you doing this in an oven or a reactor?
A reactor will work but vac oven is what I used
My favorite go to was always a reactor. I could even put a rosin bag off the spout and filter the thc with argon as it came out.

This is the way.

Bbq status…if your low and slow enough you can absolutely keep the lid on tight (better imo)
We are DE- carboxyl-ating
Thc-A… a beta ketoacid …when heated releases CO2 or potentially a BUTT ton of pressure build up and can explode in a sealed container.
As some users mentioned you can heat under vac and get her to boil off at lower temps. Go till almost no bubbles or very few form. The best way to tell if it’s done is take a tiny peice out and heat it…
If it bubbles up you know it needs to go longer. It may appear to be done…looking like distillate but if it still bubbles a lot when you heat it…it will resolidify / re nucleate or sugar back up.
Just heat it longer…LOW & SLOW is the best and you can do it with a double boiler and vac.
Made a video few years back doing the exact process.

Hope it helps someone out there. I’m grateful I found some much better thca diamonds. (Non CRC these days)

Has anyone thought about the catalytic effects of H2O, MeOH or EtOH on the decarb rxn? I.e., much lower temp.

All three of those are somewhat problematic to remove from one’s extract post decarb. A solid catalyst or one on a solid support would be better suited to the task.
MgO for instance…

Interesting. does this mean MgO is not a good drying agent for solvents…when working with the cannabinoic acids…
When one is trying to be GRAS compliant …your choice is basically EtOH and Et-O-Acetate……So MgO contamination from use as drying agent is catalyst for decarb. I need to run a few tests. Comparing to Sodium sulfate…water, ethanol, MgO…all problems. do you really have “problems dealing with H20 in THC? thanks …

You can certainly get food-grade MgO!

The point is not whether one can get GRAS MgO or MgSO4, but whether one wants to avoid it using these compounds as a drying technique when it comes to dehydrating usable GRAS solvents:
those solvents being known to be have considerable H20 that one may wish to be rid of. the problem being catalysis of decarboxylation which one does not care for if isolating cannabinoic acids. If you want to decarb…well throw it in the mix.
Perhaps, neat solid phase surface promotes decarbing…I’m just not familiar with this usage of MgO as suggested above. I don’t know about the solution/suspension chemistry?
I just want to check to see if drying EtOH with MgSO4 enhances decarbing with trace contamination.

Ah, I totally misinterpreted your previous message.
I know nothing of using MgSO4 to dry ethanol. Didn’t even know that MgO is a contaminant.
Back to your original message, a solution of THCA in ethanol in my experience decarboxylates far quicker than solid THCA. For example, an ethanolic THCA solution will absolutely decarb significantly at ethanol’s boiling point. Sadly you still need to remove the ethanol afterwards.

If you’re working with a solution that is almost entirely THC and ethanol once you’ve completed the decarboxylation, wouldn’t a simple vacuum distillation be adequate to remove the remaining ethanol? I guess the point isn’t how difficult it is, but more how much additional work it would add to a process negating any time savings.

yes I believe that would be all you needed. I am wondering if OP wants to retain terpenes or something, which would be hard to do when implementing an ethanol distillation step
