Description

Methylcyclopentane is an organic compound with the chemical formula CH3C5H9. It is a colourless, flammable liquid with a faint odor. It is a component of the naphthene fraction of petroleum. It usually is obtained as a mixture with cyclohexane. It is mainly converted in naphthene reformers to benzene.. Methylcyclopentane is not perfectly planar and can pucker to alleviate stress in its structure.

  • 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

Nocardia corallina strain V49 (isolated from soil) did not produce identifiable oxidation products when exposed to methylcyclopentane vapors when cultured on agar-resin plates, under co-oxidative conditions(1). Microorganisms were isolated from groundwater contaminated with high octane gasoline (Ambler PA)(2). Of these microorganisms, 32 pure cultures were isolated that used gasoline as a sole source of carbon; however, none used methylcyclopentane when cultured in basal mineral salts medium(2). When Sunoco 260 was added to Ambler water, methylcyclopentane showed only a 10% drop in concentration after 192 hours(2). When methylcyclopentane was incubated with Nocardia sp 802-6, 802-29, and 802-9 along with hexadecane as a co-oxidation growth substrate on agar-resin plates, no oxidation products of sufficient quantity for identification were found(2). When the fermentation was carried out in an aqueous system, similar results were obtained(2). Microorganisms used in the aqueous system were Nocardia sp 802-6 and 803-9 with hexadecane and Pseudomonas sp 803-2 with hexane(2).

12.3 Bioaccumulative potential

An estimated BCF value of 210 was calculated for methylcyclopentane(SRC), using an experimental log Kow of 3.37(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will be an important fate process(SRC).

12.4 Mobility in soil

The Koc of methylcyclopentane is estimated as approximately 1600(SRC), using an experimental log Kow of 3.37(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that methylcyclopentane should have low mobility in soil(SRC).

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.
