Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)

Specific hazards arising from the chemical
Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.

SECTION 10: Stability and reactivity
Reactivity
Highly flammable. Insoluble in water.
Chemical stability
no data available
Possibility of hazardous reactions
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as BUTYL BENZENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

Persistence and degradability
AEROBIC: n-Butylbenzene (100 mg/L) was found to degrade 72-80% after 5 days when incubated at 25 deg C with activated sludge from a wastewater treatment plant receiving predominately domestic sludge(1). n-Butylbenzene reached 12.6 and 13.9% of its theoretical BOD after 5 days at 20 deg C, using sewage and acclimated sludge, respectively(2). In a Warburg test, n-butylbenzene (500 ppm) reached 1.5-47.5% of its theoretical BOD in 6-192 hours at 20 deg C and pH 7, using activated sludge that was acclimated to benzene(3). n-Butylbenzene (500 mg/L) was found to be toxic to organisms in 2 sludges from municipal plants in Ohio during Warburg tests(4). In refinery wastewater with only natural microbial flora, n-butylbenzene did not degrade after 23 days (concentrations were not provided)(5).
Bioaccumulative potential
An estimated BCF of 470 was calculated for n-butylbenzene(SRC), using a log Kow of 4.38(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
An average of the log of the sediment to water partition coefficient (average log Kp) for n-butylbenzene of 2.00 was determined from 16 measurements(1); from this value a log Koc of 3.40 (Koc=2,510) was calculated(2). A measured log Koc of 3.39 (Koc=2,450) was reported for n-butylbenzene(3). A Koc of 2,460 was reported for n-butylbenzene(4), calculated from a measured partition coefficient of 3.69 for natural aquifer material and water(5). According to a classification scheme(6), these Koc values suggest that n-butylbenzene is expected to have slight mobility in soil.
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.
