SECTION 10: Stability and reactivity

Reactivity

Reacts with acid anhydrides, acid chlorides, bases and oxidants. Attacks steel, brass and copper.

Chemical stability

no data available

Possibility of hazardous reactions

Phenols, such as DIBUTYLPHENOL, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.

SECTION 12: Ecological information

Toxicity

  • Toxicity to fish: LC50 - Pimephales promelas - 1.4 mg/L - 96 h.
  • Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 0.45 mg/L - 48 h.
  • Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 3.6 mg/L - 72 h.
  • Toxicity to microorganisms: EC50 - a mixed population of activated sewage sludge microorganisms - > 1 000 mg/L - 3 h. Remarks:Respiration rate.

Persistence and degradability

Conversion of 1.1% of the initial concentration of 2,6-di-tert-butylphenol (50 ug) (a further 44.9% was metabolized, but not to completion)(1), 3.5%(2), and 7.7%(3) of the parent compound to CO2 by an activated sludge inoculum was reported over a 5 day time period.

Bioaccumulative potential

Chlorella, a green algae, had a measured bioaccumulation factor of 800 after exposure to 50 ug/L 2,6-di-tert-butylphenol for 24 hours(1). In fish (Golden Orfe), a bioaccumulation factor of 660 was measured following exposure to 37 ug/L 2,6-di-tert-butylphenol for 3 days(2). An estimated BCF value of 3230 was calculated for 2,6-di-tert-butylphenol(SRC), using an experimental log Kow of 4.92(3) and a recommended regression-derived equation(4). According to a recommended classification scheme(5), these BCF values indicate that bioconcentration in aquatic organisms is an important fate process(SRC).

Mobility in soil

A Koc of 3600 was measured in river sediment(1). The Koc of 2,6-di-tert-butylphenol is estimated as approximately 11,000(SRC), using an experimental log Kow of 4.92(2) and a regression-derived equation(3,SRC). According to a recommended classification scheme(4), these Koc values suggest that 2,6-di-tert-butylphenol will have slight to no mobility in soil(SRC). Following 5 days incubation, 31.9% of the initial concentration of 2,6-di-tert-butylphenol was present in the non-extractable residue fraction in sludge(5).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.

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.
