styrene oxide

CAS No. 96-09-3

Formula: C8H8O
Basic Info

Styrene oxide is an epoxide derived from styrene. It can be prepared by epoxidation of styrene with peroxybenzoic acid, in the Prilezhaev reaction: Styrene oxide is slightly soluble in water. Trace amount of acid in water causes hydrolysis to racemic phenylethyleneglycol via aryl cation. If the amount of water is not sufficient, acid-catalyzed isomerization for phenylacetaldehyde will occur.
Styrene oxide in the body is metabolized to mandelic acid, phenyl glyoxylic acid, benzoic acid and hippuric acid.

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead minnow, age 30 days, length 17 mm, weight 0.082 g); Conditions: freshwater, flow through, 23.3 (22.5-24.8)°C, pH 6.9 (6.75-7.04), hardness 53.4 mgL CaCO3 (51.9-53.9 mg/L), alkalinity 40.5 mg/L CaCO3 (40-42 mg/L), dissolved oxygen 85.5% (72.9-92.3%); Concentration: 4540 ug/L for 96 hr /97% purity
  • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea, age <24 hr neonate); Conditions: freshwater, renewal, 23.7 (23-24.5)°C, pH 8.34 (7.67-8.63), hardness 287.2 mgL CaCO3 (168-437 mg/L), alkalinity 174.2 mg/L CaCO3 (104-261 mg/L), dissolved oxygen 82.6% (75.9-95.3%); Concentration: 11600 ug/L for 48 hr (95% confidence interval: 10200-13100 ug/L) /97% purity
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Styrene-7,8-oxide, present at 100 mg/L, reached 80-82% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1); however, the test results might be for the hydrolysis product, styrene glycol(SRC).

12.3 Bioaccumulative potential

An estimated BCF of 3.5 was calculated in fish for styrene-7,8-oxide(SRC), using a log Kow of 1.61(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(SRC). Hydrolytic half-lives of 0.17, 28 and 40.9 hours have been reported for styrene-7,8-oxide at pH 3, 7, and 9, respectively(4). Hydrolysis is likely to be a more important fate than bioconcentration in aquatic organisms, particularly in acidic waters(SRC).

12.4 Mobility in soil

The Koc of styrene-7,8-oxide is estimated as 53(SRC), using a water solubility of 3,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that styrene-7,8-oxide is expected to have very high mobility in soil. Hydrolytic half-lives of 0.17, 28 and 40.9 hours have been reported for styrene-7,8-oxide at pH 3, 7, and 9, respectively(4). Hydrolysis is likely to be a more important fate than transport through soils, particularly in acidic soils(SRC).

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.
