Process to extract and purify Δ9-tetrahydrocannabinol |
| abstract |
Δ 9 -THC acid is extracted from cannabis flowers using a first organic solvent, then separated using a second aqueous solvent. Δ 9 -THC acid is converted to Δ 9 -THC carboxylic salt before being extracted by a third organic solvent and converted back to Δ 9 -THC carboxylic acid. Using a solvent swap, Δ 9 -THC carboxylic acid is decarboxylated and extracted again with an organic solvent prior to purification to give Δ 9 -THC. |
