10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

Simple aromatic halogenated organic compounds, such as 1,2,3,5-TETRACHLOROBENZENE, are very unreactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. This chemical may react with oxidizers. .

12.2 Persistence and degradability

1,2,3,5-Tetrachlorobenzene was biodegraded by an acclimated anaerobic sediment slurry obtained from the Tsurumi River, Japan(1). The first-order biodegradation rate constant was 0.037 days-1, corresponding to a half-life of about 19 days(1). The half-life of 1,2,3,5-tetrachlorobenzene in sewage sludge amended soil was 45.4 days(2). An enriched microbial culture derived from sediment of the Rhine River reductively dechlorinated 1,2,3,5-tetrachlorobenzene to 1,3,5-trichlorobenzene in 280 days after a lag period of 47 days(3). An enriched microbial culture obtained from sediment of Lake Ketelmeer, Netherlands dechlorinated 250 nmols of 1,2,3,5-tetrachlorobenzene to 1,3,5-trichlorobenzene in 300 hours(4).

12.3 Bioaccumulative potential

A measured steady state bioconcentration factor of 1800 was obtained for 1,2,3,5-tetrachlorobenzene using bluegill.

12.4 Mobility in soil

Log Koc values of 4.2(1) and 3.2(2) were reported for 1,2,3,5-tetrachlorobenzene. A log Koc value of 3.9 was measured for 1,2,3,5-tetrachlorobenzene in sediment obtained from Ise Bay, Japan(3) According to a recommended classification scheme(4), these Koc values suggest that 1,2,3,5-tetrachlorobenzene has low mobility in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.
