개요

Furfural is a colourless to amber-like oily liquid with an almond-like odour. On exposure to light and air, it turns reddish brown. Furfural is used in making chemicals, as a solvent in petroleum refining, a fungicide, and a weed killer. It is incompatible with strong acids, oxidisers, and strong alkalis. It undergoes polymerisation on contact with strong acids or strong alkalis. Furfural is produced commercially by the acid hydrolysis of pentosan polysaccharides from non-food residues of food crops and wood wastes. It is used widely as a solvent in petroleum refining, in the production of phenolic resins, and in a variety of other applications. Human exposure to furfural occurs during its production and use, as a result of its natural occurrence in many foods and from the combustion of coal and wood.

공업 용도

Also known as furfuraldehyde, furol, and pyromuclealdehyde,furfural is a yellowish liquidwith an aromatic odor, soluble in water and inalcohol, but not in petroleum hydrocarbons. Onexposure, it darkens and gradually decomposes.Furfural occurs in different forms in variousplant life and is obtained from complex carbohydratesknown as pentosans, which occur insuch agricultural wastes as cornstalks, corncobs,straw, oat husks, peanut shells, bagasse,and rice. Furfural is used for making syntheticplastics, as a plasticizer in other synthetic resins,as a preservative in weed killers, and as aselective solvent especially for removing aromaticand sulfur compounds from lubricatingoils. It is also used for the making of butadiene,adiponitrile, and other chemicals.
Various derivatives of furfural are not used,and these, known collectively as furans, are nowmade synthetically from formaldehyde andacetylene, which react to form butyl nedole.

Safety Profile

Confirmed carcinogen. Poison by ingestion, intraperitoneal, subcutaneous, intravenous, and intramuscular routes. Moderately toxic by inhalation and sktn contact. Human mutation data reported. A skin and eye irritant. Mutation data reported. The liquid is dangerous to the eyes. The vapor is irritating to mucous membranes and is a central nervous system poison. However, its low volatility reduces its toxicity effect. Ingestion of furfural has produced cirrhosis of the liver in rats. In industry there is a tendency to minimize the danger of acute effects resulting from exposure to it. This is particularly true because of its low volathty. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. Moderate explosion hazard when exposed to heat or flame or by chemical reaction. An exothermic polymerization of almost explosive violence can occur upon contact with strong mineral acids or alkalies. Keep away from heat and open flames. Mixture with sodium hydrogen carbonate ignites spontaneously. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

잠재적 노출

Furfural is used for lube oil refining and butadiene extraction; as a solvent for wood resin, nitrated cotton, cellulose acetate, and gums; in the produc tion of phenolic plastics, thermosetting resins, refined petroleum oils, dyes, and varnishes; in the manufacture of pyromucic acid, vulcanized rubber, insecticides, fungicides, herbicides, germicides, furan derivatives, polymers, and other organic chemicals.

응급 처치

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. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a qualified med ical professional might consider administering a corticoste roid spray. Cigarette smoking may exacerbate pulmonary injury and should be discouraged for at least 72 hours fol lowing exposure. If symptoms develop or overexposure is suspected, chest X-ray should be considered.

Purification Methods

Furfural is unstable to air, light and acids. Impurities include formic acid, .-formylacrylic acid and furan-2-carboxylic acid. Distil it in an oil bath from 7% (w/w) Na2CO3 (added to neutralise acids, especially pyromucic acid). Redistil it from 2% (w/w) Na2CO3, and then, finally fractionally distil it under vacuum. It is stored in the dark. [Evans & Aylesworth Ind Eng Chem (Anal ed) 18 24 1926.] Impurities resulting from storage can be removed by passage through chromatographic grade alumina. Furfural can be separated from impurities other than carbonyl compounds by the bisulfite addition compound. The aldehyde is steam volatile. It has been purified by distillation (using a Claisen head) under reduced pressure. This is essential as is the use of an oil bath with temperatures of no higher than 130o which is highly recommended. When furfural is distilled at atmospheric pressure (in a stream of N2), or under reduced pressure with a free flame (caution: because the aldehyde is flammable), an almost colourless oil is obtained. After a few days and sometimes a few hours, the oil gradually darkens and finally becomes black. This change is accelerated by light and occurs more slowly when it is kept in a brown bottle. However, when the aldehyde is distilled under vacuum and the bath temperature kept below 130o during the distillation, the oil develops only a slight colour when exposed to direct sunlight during several days. The distillation of very impure material should NOT be attempted at atmospheric pressure; otherwise the product darkens very rapidly. After one distillation under vacuum, a distillation at atmospheric pressure can be carried out without too much decomposition and darkening. The liquid irritates mucous membranes. Store it in dark containers under N2, preferably in sealed ampoules. [Adams & Voorhees Org Synth Coll Vol I 280 1941, Beilstein 17/9 V 292.]

비 호환성

May form explosive mixture with air. Acids and bases can cause polymerization, causing fire or explosion hazard. Reacts violently with oxidants. Incompatible with strong acids; caustics, ammonia, ali phatic amines; alkanolamines, alromatic amines; oxidizers. Attacks many plastics.

폐기물 처리

Dissolve or mix the material with a combustible solvent and burn in a chemical incinera tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transpor tation, treatment, and waste disposal.
