Furfuryl Alcohol

CAS RN:98-00-0

Exposure Summary

Furfuryl alcohol's production and use as a solvent, in the manufacture in resins, as a wetting agent, a gel retarder, a diluent, a liquid propellant, in flavoring, and in foundry cores may result in its release to the environment through various waste streams. Furfuryl alcohol is found in the smoke from burning wood. If released to air, a vapor pressure of 0.609 mm Hg at 25 deg C indicates furfuryl alcohol will exist solely as a vapor in the atmosphere. Vapor-phase furfuryl alcohol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.7 hours. Furfuryl alcohol absorbs light at wavelengths >290 nm and therefore may be susceptible to direct photolysis by sunlight. If released to soil, furfuryl alcohol is expected to have very high mobility based upon an estimated Koc of 34. The pKa of furfuryl alcohol is 9.55, indicating that this compound will primarily exist in its neutral form in the environment. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 7.9X10-8 atm-cu m/mole. Furfuryl alcohol may volatilize from dry soil surfaces based upon its vapor pressure. If released into water, furfuryl alcohol is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Furfuryl alcohol may be susceptible to biodegradation in the environment based on the observed degradation of 75-79% in 2 weeks and 97% in 5 days (acclimated for 20 days) in aerobic screening tests with activated sludge inoculum. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to furfuryl alcohol may occur through inhalation and dermal contact with this compound at workplaces where furfuryl alcohol is produced or used. Monitoring data indicate that the general population may be exposed to furfuryl alcohol via inhalation of ambient air, ingestion of food, and dermal contact with this compound and other products containing furfuryl alcohol. Furfuryl alcohol is widely detected in food. (SRC)
