Abstract: In alternative embodiments, provided are processes comprising the continuous isolation and purification of cannabinoids and further isomerization of the purified cannabidiol to ?8tetrahydrocannabinol (?8THC) and ?9tetrahydrocannabinol (?9THC). In alternative embodiments, provided are processes for converting ?8-THC into ?9-THC. In alternative embodiments, provided are processes for the industrial scale continuous isolation and purification of cannabinoids and further isomerization of the purified cannabidiol to ?9-THC.

Abstract: In alternative embodiments, provided are processes for obtaining or purifying a substantially pure ?8tetrahydrocannabinol (?8THC) and/or ?9tetrahydrocannabinol (?9THC) and optionally a plurality of cannabinoids or terpenes from a natural or a synthetic source, wherein the natural or the synthetic source comprises a cannabidiol (CBD) and optionally a plurality of cannabinoids or terpenes. Also provided are processes comprising the continuous isolation and purification of cannabinoids or terpenes, and further isomerization of the purified cannabidiol to ?8tetrahydrocannabinol (?8THC) and ?9tetrahydrocannabinol (?9THC). In alternative embodiments, provided are processes for converting ?8-THC into ?9-THC. In alternative embodiments, provided are processes for the industrial scale continuous isolation and purification of cannabinoids and further isomerization of the purified cannabidiol to ?9-THC.
