// Definition
A purification technique that separates compounds in a mixture by exploiting differences in their boiling points under vacuum. In cannabis processing, fractional distillation separates cannabinoids from terpenes, waxes, and other compounds, producing highly purified cannabinoid distillate.
// From the Episode
Mark Scialdone discussed the thermal chemistry of fractional distillation in episode 031, explaining how heat and vacuum separate cannabinoid fractions. Bubbleman asked about the 'molecular footprint' left by the distillation process.
