Health Hazard
Inhalation causes headache, nausea, and irritation of nose and throat. Vapor irritates eyes; liquid causes inflammation and corneal opacity. Contact of skin with liquid causes dryness and irritation. Ingestion causes headache, nausea, and irritation of mouth and stomach.
Potential Exposure
Used as a starting monomer in the production of furan resins and used to produce tetrahydro furfural alcohol (THFA).
Fire Hazard
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Chemical Properties
Furfural alcohol is a colorless to amber liquid that darkens on exposure to light. It has a faint, burning odor.
Chemical Properties
Furfuryl alcohol has a very mild, warm, oily, “burnt” odor and a cooked sugar taste.
Physical properties
Clear, colorless to pale yellow liquid with an irritating odor. Darkens to yellowish-brown on exposure to air. A detection odor threshold concentration of 32 mg/m3 (8.0 ppmv) was determined by Jacobson et al. (1958).
Occurrence
Reported found in roasted almonds, cooked apple, apple juice, roasted barley, beans, beef fat, canned beef stew, beer, brandy, white bread, cocoa, cocoa bean, roasted coffee, roasted flberts, honey, heated skim milk, dried mushrooms, roasted onion, yellow passion fruit, roasted peanuts, pineapple, popcorn, potato chips, roasted sesame seeds, cheeses, milk, meats, grape wines, cognac, whiskies, soybean products, coconut, corn oil, shrimps, clams and other sources
Uses
Solvent; manufacture of wetting agents, resins.
Uses
Colorless liquid that turns dark in air
Uses
Furfuryl Alcohol has been obtained by yeast reduction of furfural. Furfuryl Alcohol is used as solvent and in the manufacturing of wetting agents, resins.
Definition
ChEBI: A member of the class of furans bearing a hydroxymethyl substituent at the 2-position.
Preparation
Usually prepared from furfural that is obtained by the processing of corncobs; oil obtained by steam distillation of roasted coffee bean meal consists of 50% furfuryl alcohol; prepared industrially by the catalytic reduction of furfural using nickel and Cu-CrO catalysts.
Aroma threshold values

Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: The product darkens and forms water insoluble material on exposure to air or acids. This reaction is accelerated at elevated temperatures; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Carcinogenicity
The NTP conducted a 2-year inhalation study on furfuryl alcohol. F344 rats and B6C3F1 mice were exposed to 0, 2, 8, or 32 ppm furfuryl alcohol for 6 h/day, 5 days/week. All rats exposed to 32 ppm died by week 99; survival of all other animals was similar to control animals. There were increased incidences of nasal tumors in the male rats and increased incidences of kidney tubule tumors in male mice. Increased incidences of nonneoplastic lesions of the nose and increased severities of nephropathy were observed in male and female rats and male mice. Nonneoplastic lesions of nose and corneal degeneration occurred in female mice.
Source
Furfuryl occurs naturally in yarrow, licorice, sesame seeds, clove flowers, and tea leaves (Duke, 1992). Also detected in barrel-aged red, white, and model wines. Concentrations ranged from 3.5 mg/L in white wine after 55 wk of aging to 9.6 mg/L after 11 wk of aging (Spillman et al., 1998). Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996).
Environmental Fate
Biological. In activated sludge inoculum, following a 20-d adaptation period, 97.3% COD removal was achieved. The average rate of biodegradation was 41.0 mg COD/g?h (Pitter, 1976).
Chemical/Physical. Easily resinified by acids (Windholz et al., 1983). Furfuryl alcohol will not hydrolyze because it has no hydrolyzable functional group.
In barrel-aged red, white, and model wines, naturally occurring furfuryl alcohol decreased in concentration with time. In red wine, furfuryl ethyl ether was identified as a degradation product after 55 wk of storage. The average percentage decrease of furfuryl alcohol was 73% (Spillman et al., 1998).
Purification Methods
Distil it under reduced pressure to remove tarry material, shake with aqueous NaHCO3, dry it with Na2SO4 and fractionally distil it under reduced pressure from Na2CO3. It can be further dried by shaking with Linde 5A molecular sieves. [Beilstein 17/3 V 338.]

Questions And Answer

Description
Furfuryl alcohol is clear colorless organic liquid having a furan substituted with a hydroxymethyl group. It is primarily used for the synthesis of furans resins which are used in thermoset polymer matrix composites, cements, adhesive and coatings. It plays an essential role in the production of foundry sand binder and has long been used to produce cores and molds for metal casting. Other applications include as a fuel and wood treatment. In industry, it is manufactured through either direct reduction of furfural, or through the disproportionation via the Cannizaro reaction in NaOH solution. The basic raw materials for its manufacturing are waste vegetable materials such as rice hulls, sugar cane bagasse, oat hulls or corncobs.
