SECTION 10: Stability and reactivity
Reactivity
Heating may cause violent combustion or explosion. On combustion, forms toxic and corrosive gases. The substance is a strong oxidant. It reacts violently with combustible and reducing materials, amines, metals, strong acids and strong bases. This generates fire and explosion hazard.
Chemical stability
Unstable agent which like hydrogen peroxide releases oxygen.
Possibility of hazardous reactions
METHYL ETHYL KETONE PEROXIDE is a strong oxidizing agent. May be ignited by heat, sparks or flame and undergoes self-accelerating decomposition. Explosive decomposition occurs at 230° F. Sensitive to sunlight. Ignition and/or explosion may occur if mixed with readily oxidizable materials. Reacts with combustible materials such as wood, cloth or organic materials, with chlorine, and with metals (iron, copper and their alloys and aluminum and its alloys). Incompatible with strong oxidizing agents, strong reducing agents, natural rubbers, synthetic rubbers and chemical accelerators. Incompatible with heavy metals, acids and bases.
Conditions to avoid
no data available
Incompatible materials
Vigorous decomp can be stimulated by even trace amt of a wide variety of contaminants, such as strong acids, bases, metals, metal alloys and salts, sulfur cmpd, amines, accelerators or reducing agents. This is particularly true of methyl ethyl ketone and benzoyl peroxides, which are intentionally stimulated to decomp @ room temp using small amt of accelerators.

Persistence and degradability
no data available
Bioaccumulative potential
An estimated BCF of 13 was calculated for the 2-butanone peroxide mixture(SRC), using an estimated log Kow of 2(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. Chemical degradation is expected to be the dominant fate process in water because of reaction with organic matter and therefore, it is doubtful that un-reacted 2-butanone peroxide would be biologically available(SRC).
Mobility in soil
2-Butanone peroxide is a mixture dimers (50%), trimers (25%), and monomer peroxy compounds(3). Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2-butanone peroxide can be estimated to range from 10 to 11,000(SRC). According to a classification scheme(2), this estimated Koc range suggests that some portions of the 2-butanone peroxide mixture are expected to have very high mobility in soil, whereas other portions of the mixture are expected to be essentially immobile. 2-Butanone peroxide is a strong oxidizing agent(3) and may decompose when brought in contact with organic materials(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
