| Description: | Product name: Tetrahydrothiophene/Thiophene CAS Number 110-01-0 (THT), also known as "thiocyclopentane", with the molecular formula C4H8S, is a five membered saturated sulfur-containing heterocyclic compound obtained by catalytic hydrogenation of thiophene. Property Tetrahyhene is a colorless, transparent, volatile liquid with a strong unpleasant odor. Insoluble in water, miscible in ethanol, ether, benzene, and acetone. After thiophene is reduced to tetrahydrothiophene, it no longer has a conjugated system and aromaticity. Therefore, tetrahydrothiophene exhibits general sulfide properties and is easily oxidized to sulfoxides and sulfones (sulfolane). Production Obtained by reacting 1,4-dihalogenated butane with sodium sulfide in alcohol, or by catalytic hydrogenation of thiophene. The catalytic hydrogenation of thiophene is relatively difficult, and nickel catalysts are easily poisoned by thiophene and become ineffective. When using Raney nickel as a catalyst, it often leads to desulfurization reactions, resulting in butane becoming the main product. Thiophene can only be reduced to tetrahydrothiophene in the presence of molybdenum disulfide or a significant excess of palladium carbon. | |
