A Theory on BHO/Rosin Decarboxylation with Natural Terpene Preservation

As decarboxylation occurs, the CO2 gas by-product will begin fill and pressurize the headspace in the vessel, slowing down the decarb

Pretty sure most of us here have come to the conclusion that pressure / vacuum isn’t going to effect decarb time since decarbing is a process driven by energy. You’d need very high pressures to prevent that bond from wanting to break from what I’ve heard

Decarboxylation under Vacuum?

From this paper, my read is that the vacuum doesn’t substantially affect the decarb time. There are time/temp graphs about half way through. They look not dissimilar to ones from non-vacuum processes. I’m not a chemist, but my understanding of decarboxylation is that we’re basically dumping enough energy into the material to beak the bond between the carboxyl and the cannabinoid. I think that means that the primary determinant will be the heat energy applied to the material, not the pressure …
