| 독성 | Isolated from coal oil and used in the manufacture of coumarone-indene resin. This resin is used in paints, glue, etc. and is allowed in food packaging. Little is known about the toxicity of benzofuran to humans but acute toxicity in experimental animals involves liver and kidney failure. Chronic toxicity to animals involves damage to the liver, kidneys, lungs, and stomach. Lifetime administration (oral administration) caused cancer in both rats and mice. |
벤조퓨란 C화학적 특성, 용도, 생산
화학적 성질
2,3-Benzofuran is a colorless, sweet-smelling, oily liquid made by processing coal into coal oil. It may also be formed during other uses of coal or oil. 2,3-Benzofuran is not used for any commercial purposes, but the part of the coal oil that contains 2,3-benzofuran is made into a plastic called coumarone-indene resin. This resin resists corrosion and is used to make paints and varnishes. The resin also provides water resistance and is used in coatings on paper products and fabrics. It is used as an adhesive in food containers and some asphalt fl oor tiles. The resin has been approved for use in food packages and as a coating on citrus fruits. We do not know how often the resin is used or whether any 2,3-benzofuran in the coating or packaging gets into the food. 2,3-Benzofuran may enter the air, water, and soil during its manufacture, use, or storage at hazardous waste sites. Breathing contaminated air or touching the chemical in the workplace is the source of human exposure.용도
manufacture of coumarone-indene resins.정의
A bicyclic ring compound derived from coal tar naphtha, the parent substance of coumarone-indene resins.일반 설명
Clear oily yellow liquid with an aromatic odor.공기와 물의 반응
Highly flammable. May be sensitive to prolonged exposure to air. Very slightly water soluble.반응 프로필
Benzofuran slowly polymerizes on standing. Benzofuran may be sensitive to prolonged exposure to air. Benzofuran is polymerized by H2SO4.위험도
Possible carcinogen.건강위험
ACUTE/CHRONIC HAZARDS: When heated to decomposition Benzofuran emits acrid and irritating smoke and fumes.화재위험
Benzofuran is combustible.Carcinogenicity
Benzofuran was not mutagenic in bacterial assays but did cause chromosomal aberrations and sister chromatid exchanges in cultured rodent cells.Purification Methods
Benzofuran is steam distilled, dissolved in Et2O, washed with 5% aqueous NaOH, saturated NaCl, dried (Na2SO4), evaporated and redistilled. UV: max 245, 275, 282nm (log 4.08, 3.45, 3.48). The picrate has m 102-103o. [Burgstahler & Worden Org Synth Coll Vol V 251 1973, NMR: Black & Heffernan Aust J Chem 18 353 1965, Beilstein 17/2 V 3.]벤조퓨란 준비 용품 및 원자재
