Hey,
I would be curious about the solubility of various cannabinoid precursors (THCA, CBDA, etc.) in different solvents (ethanol, methanol, acetone, dimethylether, butane/pentane). Normally you would decarboxylate weed prior to extracting to get the active cannabinoids, but in this step also a lot of terpenes get lost and also the different plant ingredients start to react and may give unwanted substances in the extract. My solvent of choice would be dimethylether because of it's extremely low boiling point and non-toxicity.
I thought if it would be possible to extract the cannabinoid-acids and terpenes with a non-/ or weakly polar solvent and leaving plant sugars, proteins, etc. behind, you could heat the extract in a closed chamber. This would hinder the terpenes from evaporating and therefore may give a better extract while still decarboxylating the cannabinoids.
This also leads to one further question: Would it be possible that CO2 reacts with cannabinoids to form cannabinoid-acids again, or is this reaction not possible? (Temperature: 110°C, closed chamber with high CO2 concentration, elevated pressure)
Thanks in advance
