SECTION 10: Stability and reactivity

Reactivity

The substance may polymerize due to heating. This generates fire or explosion hazard. Reacts violently with oxidants.

Chemical stability

no data available

Possibility of hazardous reactions

Combustible. Heating will cause rise in pressure with risk of bursting.DIVINYL BENZENE may react vigorously with strong oxidizing agents. Can react exothermically with reducing agents (such as alkali metals and hydrides) to release gaseous hydrogen. May react exothermically with both acids and bases. May in the presence of various catalysts (such as acids) or initiators undergo exothermic polymerization. Inhibited by presence of an additive. When uninhibited violent polymerization may occur (NTP, 1992). Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

Conditions to avoid

no data available

Incompatible materials

Reacts with acids, oxidizing materials, peroxides, metal salts such as iron chloride or aluminum chloride, or polymer initiators.

Hazardous decomposition products

Persistence and degradability

In a 4-week biodegradation screening test (MITI test) using vinylstyrene (100 mg/l) and an activated sludge inoculum (30 mg/l), 0% of BOD was removed(1). Data regarding the biodegradation of vinylstyrene in either soil or aquatic systems were not available(SRC).

Bioaccumulative potential

A BCF range of 206-444 was measured for vinylstyrene(1). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is high(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for vinylstyrene can be estimated to be 1,700(SRC). According to a classification scheme(2), this estimated Koc value suggests that vinylstyrene is expected to have low mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
