| Dibenzofuran Usage And Synthesis |
| Chemical reactivity | Chemical reactivity is analogous to benzo[b]furan, especially electrophilic substitution reactions such as nitration, halogenation, sulfonation, acylation, and alkylation reactions. The preferred positions are 2 and 2,8, while nitration takes place at the 3- and 3,8-positions depending on the electrophilicity of the functionality. |
| Description | Dioxins and furans, two well-known environmental pollutants, are extremely toxic to humans and many other species. Dibenzofurans are released into the air from combustion sources, and are listed as pollutants of concern due to its persistence in the environment, potential to bioaccumulate, and toxicity to humans and the environment. These compounds, when adsorbed on soils or other substrates, are highly persistent under normal environmental conditions. The Office of Environmental Health Hazard Assessment reviews risk assessments submitted under the Air Toxics ‘Hot Spots’ Program (AB 2588) in which chlorinated dibenzo-p-dioxins and dibenzofurans are listed. Chlorinated dibenzofurans were calculated as total 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) equivalents in the AB 2588 risk assessments. Dibenzofuran is cited in the Clean Air Act 1990 Amendments – Hazardous Air Pollutants as a volatile hazardous air pollutant of potential concern. The Superfund Amendment Reauthorization Act Section 110 placed dibenzofuran on the revised Agency for Toxic Substances and Disease Registry priority list of hazardous substances to be the subject of a toxicological profile. Dibenzofuran is also listed in the Massachusetts Substance List for Right to Know Law, the New Jersey Department of Health Hazard Right to Know Program Hazardous Substance List, the Pennsylvania Department of Labor and Industry Hazardous Substance List, and the California’s Air Toxics ‘Hot Spots’ List (Assembly Bill 2588). |
| Chemical Properties | white to light yellow crystal powde |
| Chemical Properties | Dibenzofuran is a white crystalline powder. |
| Physical properties | Colorless crystals having a creosote-like odor. The least detectable odor threshold concentration in water at 60 °C was 2 μg/L (Alexander et al., 1982). |
| Uses | Research chemical. Derived from industrial and experimental coal gasification operations where the maximum concentration detected in coal gas tar streams was 12 mg/m3 (Cleland, 1981). |
| Uses | Dibenzofuran is an industrial chemical or by-product, and is used as an insecticide, in the production of PVC, industrial bleaching and incineration. |
| Uses | Applications for GC (Gas Chromatography) and LC (Liquid Chromatography) Analysis. Dibenzofuran as the model substrate in culture procedures. |
