Description

Dodecylbenzene is an organic compound with the formula C12H25C6H5.Dodecylbenzene is a colorless liquid with a weak oily odor. Floats on water.
This colourless waxy solid consists of a dodecyl group (C12H25) attached to a phenyl group (C6H5). Dodecylbenzene is a precursor to sodium dodecylbenzenesulfonate, a surfactant that is a key ingredient of household laundry detergents, such as detergent powder.

10.3 Possibility of hazardous reactions

COMBUSTIBLE WHEN EXPOSED TO HEAT OR FLAME; CAN REACT WITH OXIDIZING MATERIALS.Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DODECYLBENZENE, 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.

12.1 Toxicity

  • Toxicity to fish: no data available
  • 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

Various pure cultures of bacteria were shown to degrade dodecylbenzene(1,2). An activated sludge compound was shown to oxidize dodecylbenzene during a 180 hour incubation period(3). River die-away tests have shown linear alkylbenzenes are readily biodegradable, with half-lives of 4.8 and 10.1 days for C-12 isomers in river water(4).

12.3 Bioaccumulative potential

An estimated BCF of 38 was calculated for dodecylbenzene(SRC), using a log Kow of 8.26(1), and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests bioconcentration in aquatic organisms is moderate. The BCF value of bluegill sunfish exposed to dodecylbenzene in a flow-through aquarium was 35(4).

12.4 Mobility in soil

The Koc of dodecylbenzene is estimated as 7.4X10+5(SRC), using a log Kow of 8.26(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dodecylbenzene is expected to be immobile in soil.

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.

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.
