| 환경 거동 | TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 230(SRC), determined from an experimental log Kow of 1.81(2) and a recommended regression-derived equation(3), indicates that thiophene is expected to have moderate mobility in soil(SRC). Volatilization of thiophene is expected from moist soil surfaces(SRC) given an estimated Henry's Law constant of 2.9X10-3 atm-cu m/mole(SRC), determined from an experimental vapor pressure of 79.7 mm Hg at 25 °C(4) and water solubility of 3,020 mg/l at 25 °C(5). Volatilization from dry soil surfaces is expected based upon the vapor pressure of this compound(SRC).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 230, determined from an experimental log Kow of 1.81(2) and a recommended regression-derived equation(3), indicates that thiophene may adsorb to suspended solids and sediment in water(SRC). Thiophene is expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 2.9X10-3 atm-cu m/mole(SRC),determined from an experimental vapor pressure of 79.7 mm Hg at 25 °C(4) and water solubility of 3,020 mg/l at 25 °C(5). Estimated half-lives for a model river and model lake are 3 and 89, hours respectively(6,SRC). According to a classification scheme(7), experimental BCF values in the range of 2-7 measured for carp(8), suggests that bioconcentration in aquatic organisms is low(SRC). Biodegradation is not expected to be an important fate process for this compound(SRC). Using a standard BOD dilution technique and an activated sludge inoculum, a theoretical BOD of 0% was observed during a 2 week incubation period(8). No biodegradation was observed when thiophene was incubated in an aquifer slurry for a period of 1 year(9).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), thiophene, which has an experimental vapor pressure of 79.7 mm Hg at 25 °C(2), will exist solely as a vapor in the ambient atmosphere. Vapor-phase thiophene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and nitrate radicals with experimental atmospheric half-life of about 40 hours and 2.5 nighttime hours, respectively(SRC). |

| Effluent Concentrations | Thiophene was detected, not quantified, in the gas emissions of a Norwegian waste incinerator(1). Thiophene was detected at concentrations of 20-620 ppb in the leachate of a shale oil processing facility(2). Thiophene was detected in air samples above wastewater from shale oil processing facilities in Colorado and Utah at concentrations of 1-10 ng/l(3). |
| Soil Adsorption/Mobility | The Koc of thiophene is estimated as approximately 230(SRC), using a measured log Kow of 1.81(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that thiophene is expected to have moderate mobility in soil(SRC). |
| Natural Pollution Sources | Naturally occurring source of thiophene is petroleum(1,2). |
| Human Toxicity Excerpts | In man, tiophene has caused skin irritation and may induce sensitization responses. Nausea, itching and jaundice were seen in a woman repeatedly taking thiophene in suppositories. |
| Artificial Pollution Sources | Thiophenes's production and use as an organic synthesis reagent and solvent(1,2) may result in its release to the environment through various waste streams(SRC). |
| Environmental Biodegradation | Biodegradation is not expected to be an important environmental fate process for thiophene(SRC). No biodegradation was observed when thiophene was incubated in an anoxic aquifer slurry for a period of 3 months(1). Using a standard BOD dilution technique and an activated sludge inoculum, a theoretical BOD of 0% was observed during a 2 week incubation period(2). No biodegradation was observed when thiophene was incubated in an aquifer slurry for a period of 1 year(3). |

제조 및 합성 방법
생산 방법
Thiophene is present in coal tar and is recovered in the benzene distillation fraction (up to about 0.5% of the benzene present). Its removal from benzene is accomplished by mixing with concentrated sulfuric acid, soluble thiophene sulfonic acid being formed. Thiophene gives a characteristic blue coloration with isatin in concentrated sulfuric acid. The basic nomenclature of the thiophene ring system and its derivatives is indicated by the following: the sulfur atom is number 1, positions 2 and 5 are equivalent in the parent ring, as are the 3 and 4 positions.
