Description

Diphenylamine is an organic compound with the formula (C6H5)2NH. The compound is a derivative of aniline, consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities. Diphenylamine dissolves well in many common organic solvents, and is moderately soluble in water. It is used mainly for its antioxidant properties.

12.1 Toxicity

  • Toxicity to fish: LC50 Brachydanio rerio (Zebrafish) 2.2 mg/L/48 hr /Conditions of bioassay not specified
  • 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: N,N-Diphenylamine, present at 30 mg/l, reached 0% of its theoretical BOD in 2 weeks using an activated sludge innoculum at 100 mg/l and the Japanese MITI test(1).

12.3 Bioaccumulative potential

BCFs ranging from 101 to 242 and 51 to 253 (species unidentified) were measured using 0.1 and 0.01 mg/liter of N,N-diphenylamine, respectively, and a 8-week study period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

The Koc of N,N-diphenylamine is estimated as 1,900(SRC), using a log Kow of 3.50(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N,N-diphenylamine is expected to have 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.
