We are pleased to have the letter by Ian Rae published. We are proud that we were able to eliminate the use of the traditional carcinogenic solvent carbon tetrachloride by replacing it with the use of petroleum spirits. This “green chemistry” approach is an important example of what can be achieved. As Rae points out in his letter, it is important to emphasize to the academic community that the restricted use of carbon tetrachloride due to its depleting effects to the stratospheric ozone layer warrants the effort to find substitutes.

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
