Incompatibilities
Compounds of the carboxyl group react
with all bases, both inorganic and organic (i.e., amines)
releasing substantial heat, water and a salt that may be
harmful. Incompatible with arsenic compounds (releases
hydrogen cyanide gas), diazo compounds, dithiocarbamates,
isocyanates, mercaptans, nitrides, and sulfides (releasing
heat, toxic, and possibly flammable gases), thiosulfates and
dithionites (releasing hydrogen sulfate and oxides of sulfur)
Waste Disposal
Small quantities may be disposed of by burial in soil which is rich in organic matter.
Large quantities are best disposed of by incineration.
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste
containing this contaminant (5100 kg/mo) must conform
with EPA regulations governing storage, transportation,
treatment, and waste disposal. In accordance with
40CFR165, follow recommendations for the disposal of
pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting
