Chloropicrine

Halogenation of nitromethane is utilized to produce two economically important pesticides, chloropicrin [76-06-2J, a soil fumigant, and bronopol, a biocide useful for control of microbial growth in cosmetics and industrial appHcations. 

Methyl bromide is sold both as the essentially pure compound, 99.5% minimum, with not more than 0.010% water and 0.001% acidity as HBr, and with small amounts of chloropicrin [76-06-2], CCI2NO2. During 1992 methyl bromide in tank cars was priced at 1.70/kg. Methyl bromide is suppHed in 37,850- and 60,560-L tank cars and in 12,220-L ISO cylinders. Repackagers supply methyl bromide in 0.45 kg or 0.68 kg cans for such appHcations as fumigating tobacco seed beds. Alone or in formulations, it is classified as a poison, class B, and requires a poison label.

Pure propargyl bromide will dccomp violently or detonate at temps as low as 220° (Ref 2). Liq propargyl bromide is easily ignited by impact from such possible sources as water hammer or accidental pressurization of the accelerated liq (Ref 3). Tests at the BuMines showed a mixt of chloropicrin and propargyl bromide to be shock sensitive (Ref 3)...
