SECTION 10: Stability and reactivity
Reactivity
Reacts with oxidants. Reacts violently with bases, acid anhydrides and acid chlorides. Attacks steel and copper and its alloys.
Chemical stability
Slightly volatile
Possibility of hazardous reactions
Phenols, such as O-SEC-BUTYLPHENOL, 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.
Conditions to avoid
no data available
Incompatible materials
STABILITY: This compound should be stable under normal laboratory conditions. (NTP, 1992)

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - > 1 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 3.7 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 10 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - mixed population of activated sewage sludge microorganisms - > 10 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
Resting cells of a Pseudomonas strain, obtained by selective enrichment with 4-hydroxybenzoate as the sole carbon source, were able to biodegrade 2-(1-methylpropyl)phenol (oxygen uptake rate of 42 nmol O2/min/mg protein)(1). A structurally similar compound, 4-s-butylphenol (at 100 mg/L), was not biodegraded over a 2 week period using an activated sludge inoculum(2); however, a phenol-adapted yeast strain, isolated from soil, readily oxidized 4-s-butylphenol (present at 1 mmole) without a lag period(3).
Bioaccumulative potential
An estimated BCF value of 180 was calculated for 2-(1-methylpropyl)phenol(SRC), using an experimental log Kow of 3.27(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms may occur(SRC).
Mobility in soil
The Koc of 2-(1-methylpropyl)phenol is estimated as approximately 1400(SRC), using an experimental log Kow of 3.27(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 2-(1-methylpropyl)phenol has low mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
