SECTION 10: Stability and reactivity
Reactivity
Reacts with oxidants. This generates fire and explosion hazard. Attacks many plastics.
Chemical stability
Heat contributes/ to instability. ...
Possibility of hazardous reactions
Flammable, high fire risk.The vapour is heavier than air.SEC-AMYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids (NIOSH, 2016).
Conditions to avoid
no data available
Incompatible materials
Can react with oxidizing materials.
Hazardous decomposition products
When heated to decomposition it emits acrid smoke and irritating fumes.

Persistence and degradability
Biodegradation data on sec-amyl acetate were not available(SRC). However in aerobic screening tests using an unacclimated sewage seed, 4-methyl-2-pentyl acetate reached 20, 87, 62 and 69% of its theoretical BOD after 5, 10, 15, and 20 days, respectively in freshwater(1). In aerobic screening tests using synthetic seawater with added raw wastewater, 4-methyl-2-pentyl acetate reached 11, 22, 52, and 67% of its theoretical BOD after 5, 10, 15, and 20 days, respectively(1). Based upon the structural similarity of sec-amyl acetate to 4-methyl-2-pentyl acetate, biodegradation of sec-amyl acetate is expected to be an important fate process(SRC).
Bioaccumulative potential
An estimated BCF of 11 was calculated for sec-amyl acetate(SRC), using an estimated log Kow of 2.26(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of sec-amyl acetate is estimated as approximately 400(SRC), using an estimated log Kow of 2.26(1,SRC) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that sec-amyl acetate is expected to have moderate mobility in soil(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.
