Abstract

A unique liquid CO₂ extraction laboratory developed for a greener organic teaching lab curriculum provides an effective, inexpensive, and convenient procedure for teaching natural products extraction concepts and techniques using modern green extraction technology. The procedure is appropriate for the teaching lab, does not require any special equipment, and allows the students to see the phase change and extraction as they occur. Students learn extraction and spectroscopic analysis skills, are exposed to a dramatic visual example of phase change, and are introduced to commercially successful green chemical processing with CO₂.
