10.1 Reactivity

no data available

10.2 Chemical stability

Very unstable.

10.3 Possibility of hazardous reactions

Flammable solid.As a result of flow, agitation, etc., electrostatic charges can be generated. Dust explosion possible if in powder or granular form, mixed with air.PICRIC ACID, [DRY] undergoes vigorous reactions with both oxidizing or reducing agents. Apt to explode when shocked or exposed to heat. Very unstable. Readily forms salts on contact with many metals (including copper, lead, mercury, zinc, nickel, iron) that are more sensitive explosives than picric acid itself when subjected to heat, friction, or impact. Contact with concrete floors may form the friction-sensitive calcium picrate [Urbanski, 1964, vol. 1, p. 518]. Contact with metallic zinc or lead can cause detonation. Salts with ammonia, amines and complexes with hydrocarbons are less sensitive [Kirk-Othmer, 1965, vol. 8, p. 617]. Sufficiently pure samples of picric acid have the same order of stability as TNT [Chem. Eng. News, 1979, 57(41), p. 51]. Impure samples are less stable. Mixtures with aluminum and water will ignite after a delay period [Hajek, V. et al., Research, 1951, 4, p. 186].

  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Mixed cultures of phenol adapted microorganisms exhibited little or no oxygen uptake in the presence of picric acid(2,3), suggesting that picric acid is resistant to degradation under aerobic conditions. It is reported that nitrophenols can inhibit aerobic microbial growth by uncoupling the metabolic process of oxidative phosphorylation(1). Based upon information pertaining to 2,4-dinitrophenol, possible biotransformation processes of picric acid are: reduction of the nitro group, hydroxylation of the aromatic ring, and displacement of the nitro group by a hydroxyl group(4). Picric acid, present at 100 mg/L, reached 23% of its Theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5).

12.3 Bioaccumulative potential

BCF values of <0.24 and <2.2 were measured in carp (Cyprinus carpio) exposed to 500 ug/L and 50 ug/L of picric acid, respectively, over a 6 week exposure period(1). According to a classification scheme(2), these BCF values suggest that bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of picric acid is estimated as 180(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that picric acid is expected to have moderate mobility in soil. The pKa of picric acid is 0.42(4), indicating that this compound will almost entirely exist in 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
