    10.1 Reactivity

    no data available

    10.2 Chemical stability

    Stable under recommended storage conditions.

    10.3 Possibility of hazardous reactions

    An amide and amine. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generate mixed oxides of nitrogen (NOx)

    10.4 Conditions to avoid

    • Toxicity to daphnia and other aquatic invertebrates: EC50 Daphnia magna 65.9 mg/L/21 d; reproduction rate; flow through, open system.
    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: A study using a Warburg respirometer with acclimated sewage sludge and 100 mg cyanuric acid found that cyanuric acid was inhibitory to biodegradation(1). Another study using COD, TOC, and UV with activated sludge found no degradation with cyanuric acid even with acclimated sludge(2). Cyanuric acid completely degraded in a study using s-triazine herbicide production wastes, HPLC and mixed (aerobic and anaerobic) bacteria cultures(4). Biodegradation of cyanuric acid by aerated activated sludge ranges from 14% at 8.7 mg/L DO and 5 hours, to 100% at 2.5 mg/L DO and 10 hours(5). After 16 days, 87% of labeled cyanuric acid had evolved as 14-CO2 and after 192 days, the percentage had increased to 99% in grab samples of aerobic soils (cyanuric acid concN 2.5 ppm)(3). In grab samples of saturated soil, 83% of labeled cyanuric acid had evolved as 14CO2 after 66 days, and after 375 days, the percentage increased to 99% (cyanuric acid concN 2.5 ppm)(3).

    12.3 Bioaccumulative potential

    BCF values of <0.1 and <0.5 were derived for cyanuric acid at concentrations of 10 and 1 mg/L, respectively, and using orange-red killifish (Oryzias latipes) which were exposed over an 6-week period(1). According to a classification scheme(2), this BCF range suggests bioconcentration in aquatic organisms is low(SRC).

    12.4 Mobility in soil

    The Koc of cyanuric acid is estimated as 58(SRC), using a water solubility of 2,593 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cyanuric acid is expected to have high mobility in soil. The pKa of cyanuric acid is 6.88(4), indicating that this compound will partially exist in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

    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.
