Claim 0:
1. A process of converting a cannabinoid into a purified cannabinoid derivative, said process comprising:
(a) providing a starting composition comprising a cannabinoid;
(b) providing a solvent comprising a C9-C11 non-aromatic hydrocarbon;
(c) introducing said starting composition and said solvent to a conversion reactor;
(d) operating said conversion reactor at effective reaction conditions to chemically convert said cannabinoid to a cannabinoid derivative at a cannabinoid conversion selected from about 10% to about 90%, thereby generating a reaction mixture containing unreacted cannabinoid;
(e) conveying said reaction mixture to a crystallization unit;
(f) within said crystallization unit, cooling said reaction mixture from a first temperature to a second temperature that is lower than said first temperature, to precipitate at least about 50% of said unreacted cannabinoid out of said reaction mixture, thereby generating a mother liquor containing said cannabinoid derivative; and
(g) isolating and recovering said cannabinoid derivative from said mother liquor.
