| Hazard Information | Back Directory | [General Description]
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. | [Reactivity Profile]
Organosulfides, such as TETRAHYDROTHIOPHENE(110-01-0), 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. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Health Hazard]
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. | [Fire Hazard]
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. | [Chemical Properties]
colourless liquid | [Uses]
Natural gas odorant. | [Definition]
ChEBI: Tetrahydrothiophene is a saturated organic heteromonocyclic parent and a member of tetrahydrothiophenes. | [Preparation]
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. | [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]. [Beilstein 17 I 5, 17 II 15, 17 III/IV 34, 17/1 V 36.] |
