Publication number: 20250367161Abstract: The present disclosure describes a method which outlines a process for conversion of CBD to a ?9-tetrahydrocannabinol (?9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the ?9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% ?9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce ?9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% ?9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the ?9-THC using distillation and collecting an essentially pure fraction of ?9-THC using additional distillation or enrichment form of purification.Type: ApplicationFiled: August 12, 2025Publication date: December 4, 2025Inventors: Kyle OLSON, Harold MECKLER, Marcus BRACKEEN, Mario TREMBLAY
