Another Hazard
Jean B. Umland
New York, NY 10280-1063
Cover
September 2002
Vol. 79 No. 9
p. 1070
Full Text
The most serious hazard is missing from the list on page 95 of the article Soap from Nutmeg: An Integrated Introductory Organic Chemistry Laboratory Experiment (1). On standing in a partly-filled container, undergoing distillation or evaporation, diethyl ether can develop explosive peroxides. Years ago when I was distilling ether from a few milliliters of solution in a micro apparatus, an explosion occurred that blew pieces of ringstand a number of feet. I escaped serious injury only because I happened to have gone to my desk on the other side of the lab to write something in my notebook. The ether solution had given a negative test for peroxides before distillation was started.
