Description

Pentane is an organic compound with the formula C5H12 — that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer; the other two are called isopentane (methylbutane) and neopentane (dimethylpropane). Cyclopentane is not an isomer of pentane because it has only 10 hydrogen atoms where pentane has 12.
Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. Their properties are very similar to those of butanes and hexanes.

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: n-Pentane reached 0.3, 3.2 and 10.1% of its theoretical BOD after 6, 24, and 72 hours, respectively, using a benzene-acclimated activated sludge(1). n-Pentane reached 0.7, 0.5 and 0.7% of its theoretical BOD at intervals of 6, 12, and 24 hours, respectively, using aeration units of sewage treatment facilities(2). Within 24 hours, pentane was oxidized to its corresponding methyl ketone, 2-pentanone(3,5), and the corresponding alcohol, 2-pentanol(4,5), by cell suspensions of over 20 methyltrophic organisms isolated from lake water and soil samples(3-5). n-Pentane, and 12 other components of gasoline were completely degraded using an activated sludge inoculum in less than 30 days(6). n-Pentane, present at 100 mg/L, reached 96% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(7). n-Pentane, present at 18.7 ug as a component in gasoline, was incubated in a New Jersey rainwater retention pond. The median half-life of total detectable gasoline hydrocarbons was 5.0 days(8).

12.3 Bioaccumulative potential

An estimated BCF of 80 was calculated for n-pentane(SRC), using a log Kow of 3.39(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-pentane can be estimated to be 72(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-pentane is expected to have high mobility 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.
