- 안정성
- 가연성이 높습니다. 증기-공기 혼합물은 어느 정도 폭발성이 있습니다. 인화점이 낮고 폭발 한계 범위가 상당히 넓습니다. 공기보다 무거우므로 폭발 가능성이 있는 혼합물은 발화원까지 상당한 거리를 이동할 수 있습니다.

테트라히드로티오펜 C화학적 특성, 용도, 생산
화학적 성질
Tetrahydrothiophene is cyclic thioalkane, namely, saturated analog of thiophene. It is a colorless transparent volatile liquid, insoluble in water, miscible in ethanol, ether, benzene, acetone. It has a strong unpleasant odor, is stable and not easily emitted, and can be smelled in the air at 0.01PPm. It is not corrosive to gas equipment, transportation pipeline gaskets and other materials, and does not produce habitual blunting of the human sense of smell, so it is used as an odorant in LPG and natural gas, outlawing the original use of ethyl mercaptan and other odor-assigning agents.용도
Tetrahydrothiophene is used as pharmaceutical and agrochemical intermediates.제조 방법
Tetrahydrothiophene is prepared by the reaction of hydrogen sulfide and furan in the vapor phase at 400°C. This vapor-phase reaction is catalyzed by alumina(Al2O3) and other heterogenous acid catalysts.일반 설명
A water-white liquid. About the same density as water and insoluble in water. Flash point near 20°F. Vapors heavier than air. Used as a solvent and to make other chemicals.공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
Organosulfides, such as Tetrahydrothiophene, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Slow addition of hydrogen peroxide to the thiophene resulted in explosions on three occasions, Chem. Eng. News, 1974, 52(39), 3.건강위험
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.화재위험
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.Safety Profile
Mildly toxic by inhalation. Flammable liquid. Potentially explosive reaction with hydrogen peroxide. When heated to decomposition it emits toxic fumes of SOx.Purification Methods
The crude material is purified by crystallisation of the mercuric chloride complex to a constant melting point. It is then regenerated, washed, dried, and fractionally distilled. [Whitehead et al. J Am Chem Soc 73 3632 1951.] It has been dried over Na2SO4 and distilled in a vacuum [Roberts & Friend J Am Chem Soc 108 7204 1986].
