Abstract
Disclosed herein is a method of converting a THC-rich cannabinoid mixture that comprises at least about 20% THC into a CBN-rich cannabinoid mixture that comprises at least about 2.0% CBN. The method comprises contacting the cannabinoid mixture with a benzoquinone reagent under reaction conditions comprising: (i) a reaction temperature that is within a target reaction-temperature range; and (ii) a reaction time that is within a target reaction-time range, such that at least a portion of the of the THC in the THC-rich cannabinoid mixture is converted into CBN.
