Greening Dry Cleaning

Module (PDF)

Author Contact: gron@hendrix.edu

Summary

This end of chapter module outlines the current methods of nonaqueous cleaning procedures while comparing the standard solvent perchloroethylene (PERC) to risk decreasing innovations employing supercritical carbon dioxide(SCO2).

PERC is a nonpolar solvent used to dissolve hydrophobic greases and oils. Unfortunately this chemical is associated with soil contamination and long-term health consequences, being labeled a potential occupational carcinogen. As a viable alternative, supercritical carbon dioxide is being used in conjunction with specially constructed detergents to minimize risk and provide a greener solvent for the dry cleaning industry.

This module is one of nineteen end-of-chapter modules that integrate green chemistry with specific chemistry concepts within each chapter. This module includes four web investigations and three separate exercises focused on communicating findings using a variety of reporting strategies. This material included in chapter 17 entitled "Household Chemicals: Helps and Hazards."

Summary prepared January 2008 by Richard Craig Timmerman and Dana Garves, University of Oregon.
