Tetrahydrothiophene Liquid Usage and Synthesis:

Tetrahydrothiophene is a colorless or slightly yellowish transparent liquid with a melting point of - 96.2°C. The boiling point of Tetrahydrothiophene is 119°C. Boiling point 119℃. Density 1.OOg/cm3. insoluble in water, soluble in ethanol, ether, benzene, acetone. Flammable, flash point 12.8℃. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Storage temperature should not exceed 37℃. Keep the container sealed. Should be stored separately from oxidizers, do not mix storage. Use explosion-proof lighting and ventilation facilities. Prohibit the use of spark-prone machinery and tools. The storage area should be equipped with leakage emergency treatment equipment and suitable shelter materials.

Pharmacokinetics of Tetrahydrothiophene Liquid:
Tetrahydrothiophene is purified by forming an adduct of tetrahydrothiophene with mercuric chloride in ethanol. The resulting crystals are refined by recrystallization and then heated with concentrated hydrochloric acid. The resulting tetrahydrothiophene is separated from the aqueous layer, washed with water, dried with calcium chloride, and fractionated under reduced pressure. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37℃. React with halogen to get α- or α,β-substitutes. React with iodomethane to form matte salt. Adducts with mercury chloride. Can also produce sulfoxide and sulfone. Thiophene is mainly found in the fraction of crude benzene of coal tar, accounting for only 0. 5%, and the boiling point of benzene is 4℃ different, so it is extremely difficult to separate. It is expensive. Tetrahydrothiophene is produced by direct sulfurization with hydrogen sulfide in the presence of a heteropolyacid catalyst with y-Al2 03 as a carrier, using tetrahydrofuran as a raw material.

Clinical Application of Tetrahydrothiophene Liquid:
Tetrahydrothiophene is used as an odorant for city gas, liquefied petroleum gas, natural liquefied gas and other fuel gases, as well as a raw material for pharmaceuticals and pesticides. In industrial production, it can be used as solvent, intermediate of organic raw material synthesis. Used as solvent, organic synthesis intermediates. Used in the synthesis of pharmaceuticals and photographic materials. Because of the special odor, used as fuel gas additives to improve the safety of use. And the product is easy to cause combustion when it meets high heat, open fire and strong oxides. It will produce harmful combustion products such as carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur oxide and other sulfides.
