Ethylenediamine (EDA) compositions and methods for making the EDA that is suitable for use in thin-film semiconductor processing applications, are disclosed. The EDA is purified to remove water and trace metals. Water levels below about 50 ppm by weight are achieved by passing liquid through 3A type molecular sieve in a packed bed. Metallic impurities are removed by distillation and the resulting product is packaged in specially dried and optionally pre-conditioned containers.

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.
