SECTION 10: Stability and reactivity
Reactivity
Slowly oxidized in air. Insoluble in water.
Chemical stability
Slowly oxidized in air. Acidic in reaction, and forms salts with aqueous alkalis. Photolysis in acidic solution in the absence of oxygen results in hydrolysis of one chlorine atom, to give the corresponding phenol; in the presence of oxygen, the corresponding benzoquinone is formed; the same products are formed at pH 9, together with 4-chloro-2,2'-methylenediphenol.
Possibility of hazardous reactions
DICHLOROPHENE is incompatible with strong oxidizing agents and strong bases (NTP, 1992). Weakly acidic.

Persistence and degradability
AEROBIC: Dichlorophene, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). In another study, the initial rate of biodegradation of dichlorophene in sewage began rapidly (10-40 percent reduction after 1.5 days) and then slowed over a period of several days (20-55, 30-60, and 40-60 percent after 2.5, 3.5, and 7 days respectively)(2). Dichlorophene has been classified as a synthetic organic chemical unlikely to be removed during biological sewage treatment, even after prolonged exposure of the biota(3). Using a concentration of 10-20 mg/L, dichlorophene degraded 50 percent (aerobic) in an activated sludge test over a 2 week period(4).
Bioaccumulative potential
BCF values of 26 to 84 and 98 to 281 were measured for carp exposed to dichlorophene at concns of 50 ug/L and 5 ug/L, respectively, over an 8 week incubation period(1). According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is moderate to high(SRC).
Mobility in soil
The Koc of dichlorophene is estimated as 4,950(SRC), using a log Kow of 4.26(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dichlorophene is expected to have slight mobility in soil(SRC). Dichlorophene is a weak acid with pKa of 7.6(4), indicating that this compound will partially exist in anionic form in the environment(SRC). The anionic species is expected to have greater mobility in soils than the neutral species since anionic compounds typically adsorb less to soils than neutral compounds(5).
Other adverse effects
no data available
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.
