10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsFlammable in the presence of a source of ignition when the temperature is above the flash point.The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.N-PENTANE is incompatible with strong oxidizers. It is also incompatible with strong acids, alkalis, and oxygen. Mixtures with chlorine gas have produced explosions. It will attack some forms of plastics, rubber, and coatings. .

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 potentialAn 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 soilUsing 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 effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning.
