SECTION 10: Stability and reactivity

10.1Reactivity

Decomposes on heating. This produces toxic fumes including aniline and nitrobenzene. The solution in water is a weak acid. May explode on vacuum distillation.

10.2Chemical stability

Very stable toward acids & alkalies, & toward oxidation & reduction; it forms stable metallic salts

10.3Possibility of hazardous reactions

Dust explosion possible if in powder or granular form, mixed with air.The triazoles are a group of highly explosive materials that are sensitive to heat, friction, and impact. Sensitivity varies with the type substitution to the triazole ring. Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives.

10.4Conditions to avoid

no data available

10.5Incompatible materials

no data available

10.6Hazardous decomposition products

no data available

SECTION 11: Toxicological information

SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - 180 mg/L - 96 h.
• Toxicity to daphnia and other aquatic invertebrates: EC50 - other aquatic crustacea: Daphnia galeata - 15.8 mg/L - 48 h.
• Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 75 mg/L - 72 h.
• Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - 940 mg/L - 3 h. Remarks:Respiration rate.

12.2Persistence and degradability

1,2,3-benzotriazole was biol stable as source of org c for activated sludge inoculum.

12.3Bioaccumulative potential

An estimated BCF of 2.5 was calculated for 1,2,3-benzotriazole(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

12.4Mobility in soil

The Koc of 1,2,3-benzotriazole is estimated as 145(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), these estimated Koc values suggests that 1,2,3- benzotriazole is expected to have high mobility in soil. However, mobility of 1,2,3-benzotriazole will be affected by pH(2): the pKa of benzotriazole is 8.37(4), indicating that this compound will exist in the cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts.

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.

Contaminated packaging

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.
