Title (EN) PRODUCTION OF DELTA 9 TETRAHYDROCANNABINOL
(FR) PRODUCTION DE DELTA 9 TÉTRAHYDROCANNABINOL
Abstract: front page image
(EN)Δ9 THC is obtained by extracting Δ9 THC and Δ9 THC carboxylic acid from plant material using a non-polar solvent and decarboxylating the Δ9 THC acid into Δ9 THC in the same solvent, without a solvent swap, in the presence of aqueous base. The Δ9 THC is then washed to remove inorganic impurities, still in the same original solvent.
(FR)Selon l’invention, Δ9 THC est obtenu par extraction de Δ9 THC et d’acide carboxylique Δ9 THC à partir de matériaux végétaux à l’aide d’un solvant non polaire et par décarboxylation de l’acide Δ9 THC en Δ9 THC dans le même solvant, sans échange de solvant, en présence d’une base aqueuse. Le Δ9 THC est ensuite lavé afin d’éliminer les impuretés organiques, toujours dans le même solvant de départ.
