Dehydroacetic acid

CAS No. 520-45-6

Formula: C8H8O4
Basic Info

Dehydroacetic acid is an organic compound. The compound is classified as a pyrone derivative and is used mostly as a fungicide and bactericide. The sodium salt, sodium dehydroacetate, is often used in place of dehydroacetic acid because of its greater solubility in water. It is prepared by the base-catalysed dimerization of diketene.

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

A biodegradation study on dehydroacetic acid, based on BOD measurements, using an activated sludge seed, and an initial chemical concentration of 100 mg/l indicated 84% biodegradation after 2 weeks(1). Dehydroacetic acid was observed to degrade in six aerobic biodegradation tests (coupled units test, Zahn-Wellens test, MITI test, Sturm CO2 evolution test, OECD screening test, and closed bottle test)(2). 99% DOC removal was observed in the coupled units test using a sewage seed; 96% DOC removal was observed after 6 days using an activated sludge seed in the Zahn-Wellens test; 91% DOC removal was observed after 14 days incubation using an activated sludge seed in the MITI test; 100% DOC removal was observed after 28 days incubation using a sewage seed in the Sturm test; 98% DOC removal was observed after 19 days incubation using a sewage seed in the OECD screening test; and 81% BODT was observed after 28 days using a sewage seed in the closed bottle test(2).

12.3 Bioaccumulative potential

An estimated BCF value of 15 was calculated for dehydroacetic acid(SRC), using a measured water solubility of 690 mg/l(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of dehydroacetic acid is estimated as approximately 120(SRC), using a measured water solubility of 690 mg/l(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that dehydroacetic acid is expected to have high mobility in soil(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.
