Chemische Eigenschaften
Crystalline solid; melts around 102 °C(215.6 °F); practically insoluble in water,48 mg/L at 24 °C (75.2 °F) (Merck 1996);slightly soluble in hydrocarbon solvents.
Verwenden
Herbicide.
Health Hazard
Acute oral toxicity is of very low order;moderately toxic by intravenous route. LD50 oral (rat): 11,000 mg/kg LD50 intravenous (mouse): 180 mg/kg.
Environmental Fate
Soil. Neburon undergoes dealkylation of the terminal nitrogen atom, ring hydroxylation
and degradation to dichlorodihydroxyaniline (Hartley and Kidd, 1987). Residual activity
in soil is limited to approximately 3 to 4 months (Hartley and Kidd, 1987). Chemical/Physical. Neburon hydrolyzes under basic conditions forming aniline derivatives.
The half-life of neburon in 0.50 N sodium hydroxide at 20°C is 167 days (El-Dib
and Aly, 1976).
