SECTION 10: Stability and reactivity
Reactivity
The substance can form explosive peroxides under the influence of light and air. The substance may polymerize on standing. Reacts violently with oxidants. This generates fire and explosion hazard.
Chemical stability
Volatile; Stable to alkalies but readily decomposed by dilute acids.
Possibility of hazardous reactions
DANGEROUS, DUE TO FIRE AND EXPLOSION HAZARDS. DANGEROUS, WHEN EXPOSED TO HEAT OR FLAMEThe vapour is heavier than air and may travel along the ground; distant ignition possible.ACETAL can react vigorously with oxidizing agents. Stable in base but readily decomposed by dilute acids. Forms heat-sensitive explosive peroxides on contact with air. Old samples have been known to explode when heated due to peroxide formation [Sax, 9th ed., 1996, p. 5].
Conditions to avoid
no data available

Persistence and degradability
no data available
Bioaccumulative potential
An estimated BCF value of 2.6 was calculated for acetal(SRC), using an experimental log Kow of 0.84(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 low(SRC).
Mobility in soil
The Koc of acetal is estimated as approximately 68(SRC), using an experimental log Kow of 0.84(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that acetal has high 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.
