Unintentional THC Isomerization in CO2 Distillate

[Costello]

interesting that you say this became more of an issue after you started decarbing/devol under vacuum. This may very well be your culprit.

Decarb under pressure to retain terps?

This idea is reasonable, but there are a few very important caveats and notes that you must know before doing it: Pressure does not significantly affect the decarboxylation reaction kinetics, so it should proceed at normal temperatures and times, even under pressure. With enough pressure, you may find you can get away with slightly lower temperatures, but there are severe limitations on that, as described below. Of course any pressure applied should be devoid of reactive compounds like oxyg…
