Lesson 1.3.2

Hydrocarbons: Butane, Propane, and Blends

Estimated time: 60 minutes

Learning Objectives

  • Know the physical properties of n-butane and propane relevant to extraction (boiling points, vapor pressures, polarities, flash points, LEL/UEL)
  • Understand why hydrocarbons are selective for cannabinoids and terpenes while leaving behind most water-soluble compounds
  • Know why blend ratios (e.g., 70/30 butane/propane) exist and what they optimize for
  • Understand the closed-loop requirement: why hydrocarbon extraction is NEVER done in open systems
  • Know the C1D1 classification requirement and what that means for facility design
  • Understand residual solvent limits and how to verify compliance
