Tetrachlorodinitroethane is a chlorinated nitroalkane produced by nitration of tetrachloroethylene with dinitrogen tetroxide or fuming nitric acid. It is a powerful lachrymatory agent and pulmonary agent that is six times more toxic than chloropicrin. Tetrachlorodinitroethane may be used as a fumigant.
Tetrachlorodinitroethane was discovered by Hermann Kolbe in 1869 by reacting tetrachloroethylene and dinitrogen tetroxide.Hermann Kolbe (1869), Ueber Chlorkohlenstoffe, Berichte der Deutschen Chemischen Gesellschaft, "Berichte+der+Deutschen+Chemischen+Gesellschaft"+1869+kolbe&pg=PA629&printsec=frontcover
