摘要： Disclosed are methods for separating, recovering, and purifying tetrahydrocannabinolic acid (THCA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in a selected C5-C7 hydrocarbon solvent, adding thereto a selected amine to thereby precipitate a THCA-amine salt therefrom, dissolving the recovered THCA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallize a purified THCA-amine salt therefrom. The recrystallized THCA-amine salt may be decarboxylated to form a mixture of Δ9-tetrahydrocannabinol (Δ9-THC) and amine. The Δ9-THC amine mixture may be acidified to separate the amine from Δ9-THC. The recovered Δ9-THC may be concentrated to produce a highly purified Δ9-THC. Also disclosed are THCA-amine salts produced with amines selected from groups of diamines, amino alcohols, and tertiary amines.

摘要： Disclosed are methods for separating, recovering, and purifying cannabidiolic acid (CBDA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in C5-C7 hydrocarbon solvents, adding thereto a selected amine to thereby precipitate a CBDA-amine salt therefrom, dissolving the recovered CBDA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallize a purified CBDA-amine salt therefrom. The recrystallized CBDA-amine salt may be decarboxylated to form a mixture of cannabidiol (CBD) and amine. The CBD amine mixture may be acidified to separate the amine from CBD. Also disclosed are CBDA-amine salts produced with certain amines selected from groups of secondary amines, tertiary amines, diamines, amino alcohols, amino ethers, and highly basic amines.
