SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride. Reacts violently with oxidants.
Chemical stability
Stable to sunlight
Possibility of hazardous reactions
The formulated product is nonflammable.A halogenated nitrile. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.
Conditions to avoid
no data available
Incompatible materials
Dichlobenil as a suspension in water does not deteriorate. It is compatible with most wettable powder herbicides. Mixing with water soluble fertilizers or emulsifiable herbicides is not recommended.
Hazardous decomposition products
When heated to decomposition it emits toxic fumes of /hydrogen chloride, hydrogen cyanide, and nitrogen oxides/.

Persistence and degradability
AEROBIC: Dichlobenil was degraded to 2,6-dichlorobenzamide and several other unidentified metabolites by an aquatic Arthrobacter species isolated from hydrosoil(1). When dichlobenil was added to sterilized and unsterilized soil suspensions prepared from pond water and sediments, 22.9 and 3.5%, respectively, of the herbicide added remained after 4 weeks(1). The disappearance of dichlobenil from the hydrosoil and water in a farm pond treated with the herbicide was attributed in part to biodegradation(2). No quantitative information on the extent of biodegradation was given. Biodegradation of 0.05 mg/L during incubation in activated sludge for 5 days was <0.1%(3). Incubation of 14C-dichlobenil in aerobic and anaerobic soil suspension resulted in no evolution of 14CO2 in 5 days(4).
Bioaccumulative potential
The bioconcentration factor of dichlobenil in fish is 15-20(1). BCF values for dichlobenil ranged from 9.95 for bass to 18.5 for bluegill(2). Dichlobenil accumulated in edible (fillet) and nonedible (viscera) tissues of rainbow trout, largemouth bass, and brown bullhead catfish that were exposed to dichlobenil applied at 15 lb ai/A to a pond in Oregon. Maximum bioconcentration factors for edible, nonedible, and whole fish tissues were 12, 35, and 27 for rainbow trout; 10, 17, and 15 for largemouth bass; and 14, 21, and 17, respectively, for brown bullhead catfish(3). According to a classification scheme(4), these BCF values suggest bioconcentration in aquatic organisms is low to moderate(SRC).
Mobility in soil
An average Koc value of 167 was reported for dichlobenil in soils(1). Soil column studies with sandy loam and loam showed that leaching was considerably less in loam, but did occur in sandy loam depending upon the irrigation rate(2). With loam and moderate irrigation most of the dichlobenil remained in the top 10 cm, while its metabolite, dichlorobenzamide, was more readily leached(2). Koc values of 49, 110, 114, 205 and 106, were measured in a silt loam (0.6% organic matter), silty loam (1.9% organic matter), aquatic sediment (2.8% organic matter), loam (3.0% organic matter) and sand (4.8% organic matter), respectively(3). Additional Koc values of 195, 323, 272, 133 and 262 were measured for dichlobenil in a sandy soil (0.28% organic matter), hydrosoil (2.24% organic matter), silt loam (4.7% organic matter), clay soil (12.4% organic matter), and sandy loam (6.9% organic matter), respectively. According to a classification scheme(4), these Koc values suggests that dichlobenil is expected to have high to moderate mobility in soil(SRC).

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
