Abstract
Various aspects of this patent document relate to the rapid purification and decarboxylation of cannabinoids by vaporization and condensation.
Claims21
A method to purify a cannabinoid molecule from a non-volatile molecule, comprising:
- providing a composition comprising a cannabinoid molecule and a non-volatile molecule, in which both the cannabinoid molecule and the non-volatile molecule are in a liquid phase or a solid phase;
- contacting the composition with 2 kilojoules to 50 kilojoules of energy per gram of the composition to convert the cannabinoid molecule in the liquid phase or the solid phase into a vaporized cannabinoid molecule in a gas phase without vaporizing the non-volatile molecule;
- separating the vaporized cannabinoid molecule in the gas phase from the non-volatile molecule;
- contacting the vaporized cannabinoid molecule with a heat sink to condense the vaporized cannabinoid molecule into a condensed cannabinoid molecule in a liquid distillate;
- and
- collecting the liquid distillate.

15-18. (canceled)
A method to chemically-modify a cannabinoid molecule, comprising:
- providing a composition comprising cannabinoids, in which the cannabinoids comprise a native cannabinoid molecule, the native cannabinoid molecule comprises a carboxyl group, and the native cannabinoid molecule is in a liquid phase or a solid phase;
- contacting the composition with sufficient energy to convert the native cannabinoid molecule into (i) a carbon dioxide molecule and (ii) a modified cannabinoid molecule in a gas phase;
- contacting the modified cannabinoid molecule with a heat sink to condense the modified cannabinoid molecule into a condensed cannabinoid molecule in a liquid distillate;
- and
- collecting the liquid distillate.

A method to purify a volatile non-cannabinoid molecule from a cannabinoid molecule, comprising:
- providing a composition comprising a non-ionizable cannabinoid molecule and a volatile molecule selected from a terpene, terpene alcohol, or terpenoid;
- heating the composition to a temperature greater than the boiling point of the volatile molecule and less than the boiling point of the non-ionizable cannabinoid molecule to convert the volatile molecule into a vaporized volatile molecule;
- separating the vaporized volatile molecule from the non-ionizable cannabinoid molecule;
- contacting the vaporized volatile molecule with a heat sink to convert the vaporized volatile molecule into a condensed volatile molecule of a condensed phase;
- and
- collecting the condensed phase.
