Patent ID: 11872259

Abstract:
Some variations provide a process of converting a cannabinoid into a purified cannabinoid derivative, comprising: providing a starting composition comprising a cannabinoid; providing a C9-C11 non-aromatic hydrocarbon solvent; introducing the starting composition and the solvent to a conversion reactor; chemically converting some, but not all, of the cannabinoid to a cannabinoid derivative, generating a reaction mixture containing unreacted cannabinoid; conveying the reaction mixture to a crystallization unit; cooling the reaction mixture to precipitate unreacted cannabinoid out of the reaction mixture, thereby generating a mother liquor containing the cannabinoid derivative; and isolating and recovering the cannabinoid derivative from the mother liquor. Systems configured to carry out the disclosed processes are also provided. This invention offers a large-scale solution to economically convert CBD to D9-THC, among many other example. The principles of the invention may be applied to the conversion of various cannabinoids and terpenes into derivative products.
