10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Stable

10.3 Possibility of hazardous reactions

Highly flammable ... Dangerous fire ... risk.The gas is heavier than air and may travel along the ground; distant ignition possible.The unsaturated aliphatic hydrocarbons, such as 1-BUTENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. In the presence of various catalysts (such as acids) or initiators, compounds in this class can undergo very exothermic addition polymerization reactions. May react with oxidizing materials. Aluminum borohydride reacts with alkenes and in the presence of oxygen, combustion is initiated even in the absence of moisture.

  • 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

Cell free extracts and suspensions of microorganisms isolated from soil or water and raised on ethylene were found to epoxidize 1-butene to butene-1,2-epoxide(1,2). Methanotrophic bacteria isolated from soil and water were found to epoxidize 1-butene(3). Pure cultures of Pseudomonas oleovorans grown on octane oxidized 1-butene to 1-butene-3-ol(4). Bacteria isolated from soil and water and raised on propane were found to epoxidize 1-butene(5). Alkenes can be utilized by a wide range of microorganisms and are catabolized via several routes(6). These include the oxidation of a terminal methyl group leaving the double bond intact and resulting in unsaturated alcohol, aldehyde and fatty acid or oxidation of the double bond resulting in the formation of epoxide, diol compounds and possibly hydroxyacids(6).

12.3 Bioaccumulative potential

An estimated BCF of 14 was calculated for 1-butene(SRC), using a log Kow of 2.40(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-butene can be estimated to be 44(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-butene is expected to have very 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.

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.
