| Description | Furfural is an essential renewable, non-petroleum based, chemical feedstock which is primarily composed of various agricultural byproducts, including oat husks, wheat bran, corncobs, and sawdust. Chemically, furfural is an organic compound belonging to an aldehyde of furan with the odor of almonds. It is typically produced for industrial purposes, which can be used as a selective solvent in the process of refining lubricating oils and used in the manufacture of transportation fuels to improve the characteristics of diesel fuel and catalytic cracker recycle stocks. Besides, furfural is applied widely for producing resin-bonded abrasive wheels and purifying butadiene needed for the manufacture of synthetic rubber. It is also used to make other furan chemicals, such as furoic acid and furan itself. Other products of furfural include weed killer, fungicide, other solvents and etc. |

| Description | 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. |
| Chemical Properties | Furfural is a colorless to yellow aromatic het erocyclic aldehyde with an almond-like odor. Turns amber on exposure to light and air. |
| Chemical Properties | Furfural has a characteristic penetrating odor typical of cyclic aldehydes. Furfural is prepared industrially from pentosans that are contained in cereal straws and brans; these materials are previously digested with diluted H2S04, and the formed furfural steam is distilled. |
| Physical properties | Colorless to yellow liquid with an almond-like odor. Turns reddish brown on exposure to light and air. Odor and taste thresholds are 0.4 and 4 ppm, respectively (quoted, Keith and Walters, 1992). Shaw et al. (1970) reported a taste threshold in water of 80 ppm. |
| Occurrence | Reported found in several essential oils from plants of the Pinaceae family, in the essential oil from Cajenne linaloe, in the oil from leaves of Trifolium pratense and Trifolium incarnatum, in the distillation waters of several essential oils, such as ambrettee and angelica seeds, in Ceylon cinnamon essential oil, in petitgrain oil, ylang-ylang, lavender, lemongrass, calamus, eucalyptus, neroli, sandalwood, tobacco leaves and others Also reported found in many foods including apple, apricot, citrus peel oils and juices, berries, guava, grapes, pineapple, asparagus, kohlrabi, celery, onion, leek, potato, tomato, cinnamon, mustard, bread, cheeses, meats, fsh, cognac, rum, whiskies, cider, grape wine, cocoa, coffee, tea, barley, peanuts, popcorn, pecans, oats, honey, soybeans, passion fruit, plums, mushroom, mango, tamarind, fruit brandies, whiskey malt, white bread, rum, bourbon, cardamom, coriander seed, calamus, corn oil, malt, wort and other sources |
| Uses | Solvent refining of lubricating oils, resins, and other organic materials; as insecticide, fungicide, germicide; an intermediate for tetrahydrofuran, furfural alcohol, phenolic and furan polymers |
| Uses | Commercially, furfural is produced through hydrolysis of pentosan in agricultural byproducts (e.g., crop wastes). It has a diverse applications which include as a solvent in various manufacturing industries (e.g., petroleum and automotive products), accelerant for vulcanization of rubber, raw material for manufacturing furan derivatives (e.g., tetrahydrofurfuryl alcohol) and synthetic resins, wetting agent, flavoring ingredient for foods (e.g., roasted coffee), fragrance in consumer and personal care products (e.g., fragrance cream, bath products, toiletries), and pesticides for controlling unwanted microorganisms, fungi, weeds, insects, and nematodes. The application methods for pesticidal use include drip irritation, spray boom, sprinkler, and low-pressure back-pack spray. |
| Uses | In the manufacture of furfural-phenol plastics such as Durite; in solvent refining of petroleum oils; in the preparation of pyromucic acid. As a solvent for nitrated cotton, cellulose acetate, and gums; in the manufacture of varnishes; for accelerating vulcanization; as insecticide, fungicide, germicide; as reagent in analytical chemistry. In the synthesis of furan derivatives. |
| Definition | furfural: A colourless liquid,C5H4O2, b.p. 162°C, which darkenson standing in air. It is the aldehydederivative of furan and occurs invarious essential oils and in fuseloil. It is used as a solvent for extractingmineral oils and natural resinsand itself forms resins with somearomatic compounds. |
