Abstract:
Δ9-THC carboxylic acid is extracted from cannabis flowers using a first organic solvent, then separated using a second aqueous solvent. Δ9-THC carboxylic acid is converted to Δ9-THC carboxylic salt before being extracted by a third organic solvent and converted back to Δ9-THC carboxylic acid. Using a solvent swap, Δ9-THC carboxylic acid is decarboxylated and extracted again with an organic solvent prior to purification to give Δ9-THC.
