IMPROVED METHODS FOR CONVERTING CANNABIDIOL INTO DELTA9-TETRAHYDROCANNABINOL UNDER PROTIC REACTION CONDITIONS

Disclosed herein is a method for converting cannabidiol (CBD) into a composition comprising Δ9-tetrahydrocannabinol (Δ9-THC) and Δ8-tetrahydrocannabinol (Δ8-THC) in which the composition has a Δ9-THC:Δ8-THC ratio of greater than 1.0:1.0. The method comprises contacting the CBD with a Lewis-acidic he...

Zusammenfassung:	Disclosed herein is a method for converting cannabidiol (CBD) into a composition comprising Δ9-tetrahydrocannabinol (Δ9-THC) and Δ8-tetrahydrocannabinol (Δ8-THC) in which the composition has a Δ9-THC:Δ8-THC ratio of greater than 1.0:1.0. The method comprises contacting the CBD with a Lewis-acidic heterogeneous reagent under reaction conditions comprising: (i) a protic-solvent system; (ii) a reaction temperature that is less than a threshold reaction temperature for the Lewis-acidic heterogeneous reagent and the protic-solvent system; and (iii) a reaction time that is less than a threshold reaction time for the Lewis-acidic heterogeneous reagent, the protic-solvent system, and the reaction temperature.
