Lesson 1.6.3

Solvent Recovery and Purging

Estimated time: 45 minutes

Learning Objectives

  • Execute solvent recovery via rotary evaporation: bath temperature, rotation speed, vacuum level, condenser temperature
  • Know residual solvent limits for finished products (state-specific, but typically < 5,000 ppm for ethanol, < 5 ppm for Class 2 solvents)
  • Purge residual solvents with a vacuum oven: temperature, vacuum depth, time, and how to verify
  • Understand solvent recovery rates and their impact on production economics
