History and Production
Pure EGDN was first produced by L. Henry in 1870 by dropping a small amount of ethylene glycol into a mixture of nitric and sulfuric acids cooled to 0°C. The previous year, August Kekulé had produced pure EGDN by the nitration of ethylene, but this was actually contaminated with beta-nitroethyl nitrate.
EGDN can be produced either through the nitration of ethylene glycol:
- C2H4(OH)2 + 2 HNO3 → C2H4(ONO2)2 + 2 H2O
or through the reaction of ethylene oxide and dinitrogen pentoxide:
- C2H4O + N2O5 → C2H4(ONO2)2

Famous quotes containing the words history and/or production:
“Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon than the Word of God. It is a history of wickedness that has served to corrupt and brutalize mankind.”
—Thomas Paine (1737–1809)
“The production of obscurity in Paris compares to the production of motor cars in Detroit in the great period of American industry.”
—Ernest Gellner (b. 1925)
