ADVANTAGES

No, they are quite different operations. With extraction, solids, (or sometimes liquids) are brought into contact with a solvent. In cannabinoid work, the solvent is typically ethanol, or butane/propane, or supercritical pressurized CO2, or others. Certain compounds such as cannabinoids, terpenes, chlorophyll are dissolved into the solvent, after which the solvent is evaporated away. The separation is accomplished via an affinity of the target compounds to be transferred by dissolution into the solvent. With distillation, the separation is carried out not by solvent affinity, but by differences in the volatility (boiling points), between the various com pounds. More volatile materials are more easily distilled and condensed as distillate while the heavier materials remain as liquid collected as residue. Distillation is performed after extraction to further concentrate and purify the desired compounds.
