Фурфуриловый спирт химические свойства, назначение, производство
Химические свойства
Furfuryl alcohol has a very mild, warm, oily, “burnt” odor and a cooked sugar taste.Физические свойства
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).Вхождение
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 sourcesИспользование
Furfuryl Alcohol has been obtained by yeast reduction of furfural. Furfuryl Alcohol is used as solvent and in the manufacturing of wetting agents, resins.Подготовка
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.Определение
ChEBI: A member of the class of furans bearing a hydroxymethyl substituent at the 2-position.Общее описание
A clear colorless liquid. Flash point 167°F. Boiling point 171°F. Denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion and skin contact and moderately toxic by inhalation.Реакции воздуха и воды
Slightly soluble in water.Опасность
May react explosively with mineral acids and some organic acids. Toxic by inhalation and skin absorption. Approved for food products. Toxic by skin absorption.Угроза здоровью
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.Пожароопасность
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.Химическая реактивность
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.Профиль безопасности
Poison by ingestion, skin contact, and subcutaneous routes.Moderately toxic by inhalation and intraperitoneal routes. Mutation data reported. An eye irritant. Flammable when exposed to heat or flame; can react with oxidtzing materials. Moderate explosion hazard when exposed to heat or flame. Reacts violently with acids (e.g., formic acid, cyanoacetic acid + heat). Ignites on contact with 85% hydrogen peroxide. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes.Возможный контакт
Used as a starting monomer in the production of furan resins and used to produce tetrahydro furfural alcohol (THFA).Канцерогенность
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.Экологическая судьба
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).
