Im currently looking to transition from decarbing winterized hemp crude in 50L rotos, to deacarbing in a 30L jacketed reactor. What would be the optimal speed for agitation using this method? I have the reactor at 120C, and the only time I can observe a reaction is when I throttle the speed momentarily.
You should be pulling a light vacuum to pull volatiles and co2 from your viscous crude oil.
Activated alumina will lower the temps required for your decarb, and will allow for decarb at room temperature- you need to keep the oil suspended in a solvent in order to do this effectively however
Alumina will also remove a ton of impurities, I suggest running your material through an alumina plug post extraction, it will pull water out of your ethanol along with many water soluble contaminants and go a long way in lowering your decarb time in the reactor and exposure to high heat that degrades your oils
@rowan I’m so glad you’re back man! I should welcome you back and ask for nothing in return BUT since I’m a whore for data:
How RT are we talking with that alumina? I messed with MgO briefly and found it not effective for decarb at reasonable reflux temps (admittedly, not a lot of time was spent on this and it was not the most empirical experimentation). I always assumed alumina was a much less impactful catalyst for the reaction but well, what the fuck do I know lol
That I was not referring to this, and previous convo was taken out of context… However I will entertain his response as he is a valued member and deserves that respect EDIT: And I could not help to poke the bear on a harmless friendly convo. Edit: joke is dead.
Decarboxylation is caused by cleaving part of the molecule, using high enough temps to cause that group to fall off the molecule. That’s where the co2 comes from. It’s not influenced by a change in boiling point because it’s a molecular bond being broken.
Completely agree lol. The original convo was regarding maintaining potency and why I would pull a light vac (to remove volatiles and co2)… And I was being a bit of a smartass, but there is a valid reason for pulling a light vac to remove volatiles and co2 for multiple reasons.
