98-01-1 structure, C5H4O2






Basic Info

Furfural is an organic compound derived from a variety of agricultural byproducts, including corncobs, oat, wheat bran, and sawdust. The name furfural comes from the Latin word furfur, meaning bran, referring to its usual source.
Furfural is a heterocyclic aldehyde, with the ring structure shown at right. Its chemical formula is OC4H3CHO. It is a colorless oily liquid with the odor of almonds, which quickly darkens when exposed to air.
It is one of the components found in vanilla.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Lepomis macrochirus (Bluegill) 32 mg/L/24 hr; static /formulated product
  • Toxicity to daphnia and other aquatic invertebrates: LC50 Daphnia magna (Water flea) 36 mg/L/24 hr; static /formulated product
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Furfural, present at 100 mg/L, reached 93.5% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). In river die-away studies using water taken from the Great Miami, Little Miami, and Ohio Rivers, 1.0 ppm of furfural was completely degraded within 3 days under aerobic conditions(2). The rate of degradation at a higher initial furfural concentration was found to be dependent upon the degree of acclimation, and fully acclimated seeds were round to degrade 25 ppm furfural within 5-12 days(2). At initial concentrations of 1.7-20 and 440 ppm, furfural underwent 46% and 17% theoretical BOD, respectively, in 5 days using a sewage sludge seed under aerobic conditions(3). Furfural at an initial concentration of 300 mg/L, in solution with phenol and N-methyl-2-pyrolidine, was found to undergo 98% removal in a flow-through laboratory bioreactor using an activated sludge inoculum under aerobic conditions(4). At an initial feed concentration of 1,000 mg/L, degradation was also found to occur(4). Furfural at an initial concentration of 200 mg/L COD underwent 96.3% removal in less than 120 hours using a thickened adapted activated sludge under aerobic conditions (5). Furfural was shown to support the aerobic growth of organisms obtained from soil and grown on phenol(6).

12.3 Bioaccumulative potential

An estimated BCF of 3.2 was calculated for furfural(SRC), using a log Kow of 0.41(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).

12.4 Mobility in soil

The Koc of furfural is estimated as 40(SRC), using a log Kow of 0.41(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that furfural is expected to have very high mobility in soil.

12.5 Other adverse effects

no data available
